Hello XDA Developers.
I have hit a brick wall trying to partition my 8gb SD card for my MyTouch3g, and could use a little help, i can getting very frustrated and any help will be appreciated .
Questions:
1) Is there any way to partition the 8GB SD card on the computer, then just put it into the MyTouch3g?
2) How do i know what size partitions should be for my 8GB card?
I cannot get adb set up on the computer properly to do it, also many of the guides are for the G1 and involve typing things in the recovery console with the hardware keyboard.
I have googled for hours trying to find a guide specifically for partitioning with the Mytouch3g without using adb, but could not find one.
Side note: I rooted my phone using the 1touch method.
you can use Amon_Ra's recovery and it'll do it for you automatically.
http://theunlockr.com/2009/08/22/how-to-root-the-mytouch-3g-or-g1-in-one-click/
...
maybe dumb question, can i flash the Amon_Ra's recovery img after already having the cyanogen recovery img...or do i need to start with a clean slate?...and any advice if im using the stock 4gb SD card as far as partitioning/format for better performance?
i need help too...
please help a noob!!!
i'm in the exact same boat. using cyanogen 4.0.2 also and an 8gb sd card too.
please help...
Same
Yeah im worried about flashing another recovery image over the Cyanogen recovery image.
I rooted using the 1-touch method that auto installed Cyanogen Recovery image....dont know if flashing another recovery image would brick it or not
if you guys have the myTouch and unsure, unroot then root again using the Amon_Ra method on unlockr

I use Amon_Ra's recovery and I know it does the partition for me automatically, but how do I know what size my partitions are ? For example, there are some roms that require 96Mb's for Swap...Any help will be greatly appreciated and thanx to all the Devs for their hard and continous work on the G1 and MT3G....

Did you ask this in every thread?............search please!!!!
Cyan's recovery should have an option to auto format your card
you can use Amon_Ra's recovery img without flashing it to your phone!
Just boot it, instead of flashing it.. and select the option to partition the sdcard and then reboot...
No changes to your phone... just a partitioned sdcard!
use the following commands with fastboot loaded on your phone (back + power)
fastboot boot your_recovery_img.img
Hope this helps

does this really work? first time i have seen this reported. Have you done it? If you have could u give me some more detailed instructions on how to do it. Please and thank you. If this is a totally noob request I apologize,I am new to this.
Follow this guide and you can partition the card how you like.
http://forum.xda-developers.com/showthread.php?t=535914
It really is easy to do, just try.
Here's what I am doing. I'm a complete noob and it took days and days of tinkering and reading through this site to refine this. I've done it multiple times now with experimental ROMs and it works great for me.
Put your SD card in your computer's reader, or a 3rd party reader device. Copy all the files to your hard drive in a backup folder of some kind.
Go get GParted at http://gparted.sourceforge.net/
You can download the iso image. Use a program like http://www.imgburn.com/ to burn the iso image to a CD which will be bootable.
Once you have the Boot CD with GParted you can boot your computer up with it in the disc drive. Make sure your BIOS settings have the CD before your hard drive to check for boot sequence.
GParted will start up, I pick the defaults. It reads my SD reader with my 8GB Class 6 inserted. Make sure you select your SD card from the drop menu, the default is my computer hard drive which you don't want to touch!
I delete all the partitions on the card.
The first partition is your FAT32 and it will be the largest partition.
The next Partition you want to make is an ext2, ext3, or ext4 partition. I use ext3. I make this partition about 800 MB. This is where the Cyanogen ROM will copy your apps to automatically when it detects it.
The last partition is going to be a Linux Swap file and should be about 32 MB.
I've seen where some people use a 64 MB swap file but I think the general consensus of 32 is fine.
Once you are done, close out GParted and pull the CD out when it ejects your tray. When you reboot the computer without the CD in it, your Windows OS should boot right up like normal.
In Windows you should see the large FAT32 partition on your SD card. Windows won't see the ext3 or swap partitions. Copy your SD card files back to your SD card and eject the card.
When you put the card in your MyTouch3G, turn on the phone. Leave it alone when your screen comes up. The Cyanogen ROM will detect your ext3 partition and begin copying all your apps to it. At first it will look like you have no apps but they will begin appearing as they are copied to your SD card. It may take a couple minutes depending on how many apps you have.
The GParted CD is an easy way in the future to wipe out partitions on your card and set it up for you.
Question:
I've noticed I'm pretty much at my limit for space on my current SD card (like 80MB remaining on a 4GB!)...
I've ordered an 8GB card to replace this one... but how can I "clone" my current 4GB card (with a2sd partitions) and then copy it over to my 8GB card, without losing data, settings, apps, etc? Is there a way?
Thanks in advance.
Do this all from within Clockwork Recovery:
1) Make a nandroid backup
2) Connect the phone to a computer
3) Partitions menu > mount USB storage
4) Copy all contents from the old SD card to a temporary folder on your computer (including the clockworkmod folder which contains the nandroid backup you just took)
5) Unmount and disconnect from computer.
6) Pull battery to shut the phone off, or if you would prefer you can boot the phone and then turn the phone off immediately afterward. Pulling battery just saves time.
7) Put new SD card in
8) Boot into clockwork
9) Format the card with Clockwork w/ ext partition
10) Connect to computer, mount USB storage again, copy all files back to the phone
11) Unmount and disconnect cable from computer
12) Nandroid > advanced restore > Restore sd-ext only
13) Reboot and you're done.
And if something goes wrong, it's not really a big deal since you will still have the original files on the old SD card so you can try again or ask for help to try another method.
Sounds complicated enough to work. I'll try when the card comes and let you all know. Thanks!

Haha yeah, I think it's the easiest way to do it with Windows, since you can't read the ext partition from the computer. You could probably just copy the contents of both partitions through Linux if you're comfortable doing that.
Doesn't a nandroid backup the ext partition too?
If you're using windows you could just backup your fat32 partition on your PC and partition your new card and then copy all your files back and do your nandroid restore.
I think this would work...

Clockwork does not back up my ext partition. It can't mount it or anything. Not sure why. Might be because its ext4, but when I do nandroids the sd-ext backup always fails.
I have to use Ubuntu and mount as storage. Then both of my partitions mount on my computer and I can do as I please. For me this seems easiest anyway. Simple copy and paste and it can be done from a live cd for those that dont already have Ubuntu.

What version has that menu option? I don't see it.
Interesting. I was sure you could format a card with ext partition through Clockwork but apparently you can't. You can do it through ROM Manager though, so I guess you may have to boot into the phone to get to it.
The programs on the ext partition won't show up yet of course. Don't be alarmed. Just partition the card through ROM Manager, then once you're done doing that, do the nadroid advanced restore. If there are any problems after a reboot (i.e., it didn't work correctly), go back and try doing the regular full nandroid restore.

v2.5.0.1
This doesnt create a partition though. It just formats an existing partition. You'll have to use drumist's method of going through Rom manager to actually create the ext3 parition from the phone.

Tried running ROM Manager - of course, it's installed on the 4GB card which isn't on my phone when I have the 8GB in to format. So then I re-installed it using the APK... but I get the exclamation mark when it boots to recovery to format... probably because a2sd is installing the same program on the ext part which it is now trying to format.
I think I'm going to have to format/partition it using Linux somehow instead, no?

someone recommended in another thread that when that happens you just pull out the battery and then use volume down+power to boot back into recovery and it should then work.
But the method I use is to do it from Ubuntu (a linux version). If you dont want to install Ubuntu on your computer you can make a bootable CD or USB drive with Ubuntu on it (directions for this are on the Ubuntu download page) and actually run Ubuntu from the CD/USB without ever installing it on your computer. From there you can use gParted to create paritions. And while I recommend making backups, gparted even allows you to resize and move partitions without deleting anything.

Yeah, that's what I was worried about. My suggestion then is to format the card through linux if you have a SD card reader. Easiest way is to use an Ubuntu LiveCD. Do you know how to do this on your own?
Also, definitely do a full nandroid restore once the SD card is reformatted. Since you booted the phone and tried to install an app, it's possible something got screwed up -- nothing to worry about though because a full nandroid restore should revert everything.

I'm reverting back now, going to sleep on it, and then investigate formatting it via LiveCD tomorrow morning. It's been several years since I've had to go near anything Unix.
By the way, another option is to just do a clean install on your phone with a ROM that has ROM Manager built in. Use that to do the format on the SD card.

That got me thinking...Ive never had a problem adding an ext partition using Rom Manager. Ive done it to 3 SD cards now without a single issue. BUT, Ive also always done it while on cm6/7 which both came with Rom Manager pre-installed with the rom and quite a bit of integration with the rom manager app...just a thought...
EDIT: Scratch that, I used it for 2 SD cards, the 3rd was done with Ubuntu.
Here's my post from the other thread
jdwhite87 said:
Rom manager - partition SD card - choose your partitions. It will reboot into recovery and try but fail to partition your card. Pull battery. Replace battery - hold volume down and power. Wait for it to try and find the libde. Img then press volume down and it will highlight recovery then press power. It will boot into recovery and finish partitioning your card.
I think that's how I got it to work.

I did this with two different SD cards on fr008. Both were sandisks. One was a 16 gb class 4 and the other was an 8 gb class 6. I couldn't get gparted to partition the 8 gb for whatever reason. I didn't know what Ubuntu was when I partitioned the 16 gb
It seems like an oversight that maybe of the masses of people with Android devices that one day the general (non-xda) population would want a simple way to transfer their sd card data to a larger card...
I Imagine there are a bunch of people out there clueless.
Hell, I read XDA and there was still no clear simple way in this thread.
(I got here from a Google search for SD CARD CLONE)
Got it to work, finally. Required some back-and-forth with the Nandroid backups, but I have everything running off of my 8GB SD card now, without reinstalling!
Now, to sell off my 4GB card... anyone?
Hi,
First off if this is answered I am sorry.
I did a lot of searching and was unable to see the answer to this...
I am running CM7.1 off uSD. Install went well, and have no issues. That being said, I am unable to find out where on the card to sideload books. I have booted into CM7.1, turned on USB storage, and have 2 drives appear in win: MYNOOK and CM7 SDCARD. I used the size agnostic image, and it appears that there is only the single partition on the card, and in file explorer, it shows the correct card size for memory, but only the single partition.
The only folders appearing on the card are:
.android_secure
Android
LOST.DIR
I tried to manually copy the books, media, etc. folders into a My Files folder on this drive, without success.
There is no other partition to repartition (shouldn't have to do that with size agnostic?). I have no problem loading books into the MYNOOK book folder, which I assume is the internal device memory.
Here is my question. How/where do I sideload books to use the storage on the uSD card? Do I have to create the folders somewhere? If so where?
My goal is to utilize the storage available on the card, but be able to read the titles in the stock software. Is it possible to do this without rooting, or do I need to root for any reason to access the right folders on the card for storage?
THANK YOU ALL!!

In what way was it not successful? Did the files copy and just can't find them with a reader? If so which reader?
The book I transferred over was not found in the stock software when I opened my library. Is there somewhere specific I am supposed to place it on the card for the Nook to see it? Thanks!
For the stock reader, I think you must use the 1gb area of the internal memory drive, which shows up as a separate drive on your PC when you plug it into the computer. When you are in CM7 and connect to the pc, cancel when it tries to install a device for the NC. Check the notifications on the NC, you need to click a button to enable copying files from your pc, and take care to properly safely remove/eject before disabling that and disconnecting the cable from your pc. Better to get a separate reader and install it from the market (e.g., Cool Reader). You can also install the Nook app from the market, but then books need to go within (possibly in a specific subdir) of the "Nook" folder on SDCARD.
So there is no way to use the card memory to store books if I want to use the stock reader??
Should there have been a "NOOK" folder created on the SD card as part of the CM7 process? Is that a file that the user needs to create? If so, does it go in the same partition as the CM7, as that is the only partition my machine is able to see?
thanks again
Hopefully you'll get more input on this, but I think the point of keeping the Nook stock available (aside from not voiding your warranty) relates to use of B&N books. However you can eject your CM sd card and use another sd card if you want more space for user media for use with the stock app. I thought the media drive was the 1gb area, but now I'm not so sure because on mine the MYNOOK disk is much smaller.
When you are in the stock firmware... you are seeing the boot partition of the uSD...
You can write the boot partition... resize it... then run the installer...
I have done it in the past... set up a 2GB boot partition... then setup the ROM on uSD. You then have a 2GB partition you can use when in stock.
Thanks for the info. I am a bit confused by your suggestion, can you please offer a bit more?
By writing the boot partition, then resizing it, does that mean I can resize now, after I have already set everything up? If so, what do you mean by the installer? Or do you mean I have to wipe the card and start over? If that is the case (start over) do you mean wipe the card, create a small partition for the boot to install on? Would that requre the use of an image that is not size agnostic?
Either way, how do I get the file structure in place on the non boot partition for the nook to see files that are saved there?
Thanks again for any help you can provide!
I have never had luck resizing it after it has been booted in the Nook and all the partitions created...
I have written the size agnostic image to the card... resized the only partition created at that point... then put the ROM on it and booted it in the nook so the installer script (size agnostic recovery) can do the partitioning and install the ROM.
For the question of getting the file structure... I'd have to ask how you wrote the files on the uSD... were you CM or stock?
I had always planned on running cm from the card, so when I wrote the files to the card, I was stock.
If I follow what you are saying, then steps for me to try at this point would be:
1. Reformat card
2. Write the disk image to the card
3. Shrink the single partition on the card (where the image is)
4. Add the CM ROM to same partition as the image
5. Install card and boot device
If this sounds right, I have 2 questions.
What size should the partition be for the image and CM ROM, maybe 2GB?
Will the Nook "see" the non-CM partition and create the file structure for saving files on the 2nd partition at some point? In my searches I saw that in early versions, there was a requirement that the 4th partition on the card be expanded to use for storage, won't I only have 2 at this point?
Thanks again so much for the help!
When you write the image to the card... it will only be about 114 MB.... you will probably want to increase the size to avoid any possible size issues later (with ROM's getting larger)
If you plan to use the stock nook ROM as well as CM7... you will probably want 2 GB boot partition... otherwise if you plan to only run CM7 you probably only want about 250 MB.
You can modify vold.fstab on the stock ROM to use partition 4 of the SD for its SD use... then you could avoid the 2 GB boot partition.
What happens when you use VG's SASD... the boot image is about 114 MB... when you boot it in the nook it creates partitions 2, 3 and 4... 2 and 3 are ext3 partitions, partition 4 is fat... partition 4 is the one set for sdcard in the ROM booted from SD...
This is why you can modify stock vold.fstab to point to partition 4... then both ROM's will be putting stuff on the same partition for "SD Card"
I think I follow that, but my issue is that currently I am unable to see partition 2,3 or 4 which I think is part of my problem.
When I set up the card, I used the SASD method, and all I can see in both win explorer and partition software is the single partition on the card. Should there also be partitions 2,3, and 4? Do I have to do something to make those partitions viewable?
I am not comfortable enough with my skill level to attempt to modify the stock vold.fstab file on the device, and was hopeful that by properly setting up the card, I would be able to keep stock as is, and use the card to multipurpose, ie run cm7 on part and use the remaining space on card to store books to be read in stock firmware. I am still hoping to do that....thanks
As far as only seeing partition 1.... that is a limitation of Windows.
By following the advice pertaining to starting over and increasing the size of the Boot partition immediately after writing the image... before doing anything else... you can provide more space for the stock ROM to use on the SD... it will use partiton 1 (the boot partition) without the other modifications to vold.fstab
ok, confused again
If I start over, write image, then resize that partition with the image, am I going to use the "rest" of the card, NOT in that partition to use with storage? OR am I going to resize the partition with the image to be big enough to use as the partition to put books on?
If it is the former, don't I again run into the problem of how to find the other partitions, or will I create them when resize the first partition after writing the image?
Thank you!
You will only ever see the first partition of the sd card when booting from the stock OS. Also with the card inserted in a usb flash card reader on Windows you can only mount the first partition as a drive letter. But you can see and resize partitions with contiguous unallocated space using MiniTools Partition Wizard.
OK thats good to know. Do you know if the SASD install should have created other partitions when I installed to the card? The reason I ask is that even in Partition Wizard, I am still only able to see the 1 large partition with everything in it.
If I start over again, will I need to use the wizard to create partitions first, then write the image to the resized 2 GB first partition, or should I write image to card, resize the first partition? If the latter, will resizing the first partition autmatically force the other partitions to be seen? I am not sure of this option, as I can't see where in the process the other partitions are created? Is this part of the process when CM7 boots?
Thanks!
Write the image. Safely remove from pc. Reinsert to pc. Use minitool partition to resize the (only, at that point) partition to the size you want. Use Apply in minitool software. Quit minitool and resume with the card setup.
does the minitool at that point (resizing) create the other partitions, or will the card setup do that? Do I have to do anything else to the other partitions to make them visable to the stock nook so that they can be used to access books while in stock os?
The card setup will create the other partitions. The stock os is never going to see anything but the 1st partition. You would need a terminal emulator or rooted file explorer installed in the stock os in order to mount another partition.
If that is the case, that stock os will never see anything other than the 1st partition, then there really is no way to accomplish what I am trying to do, correct?
In other words, put CM7 on the card, then when I want to use stock, boot into stock and have the reader find books saved on the card?
Hi everyone!
I just got CM7 (latest stable release) installed on on external sdhc card. I have wifi issues with CM7 (and looking around the forums tells me that CM7 can be finicky with certain routers) so I would love to be able to use Nook's stock ROM (4.1.4) when I am having issues.
But, when I am on NC ROM, I don't see anything except the small boot partition on the SD and when I am on CM7, I don't get access to this boot partition. I am wondering if there is a way to either create another partition or make the currently existing partitions accessible on both ROMS so that I can share data between them.
I am a n00b without any Android experience so thanks in advance for your patient responses.

If whatever you have on emmc is rooted, you can manually edit it. If you have unrooted stock, then you need to flash the zip since without root you cannot edit those files manually. And I did mean item B3. Each item is a different topic, they are not steps. One topic does not depend on another. Just do B3 and no others if you want.
Yes, item B3. My mistake...
I should be able to do flash the zip from my current CM7 SD card's boot partition, shouldn't I?
So I put the update-stockemmc-vold-fstab-modified-for-partition4.zip file in the boot partition of the SD card, rebooted to Recovery mode and then booted to NC's stock ROM. NC is still using the tiny boot partition on the SD card as my external storage instead of the much larger CM7 partition. This was the same partition that was under 'My Files / Memory card' before I flashed so nothing has changed. I did this twice to double-check.
Am I doing this wrong?

Yes you are doing it wrong. You need to flash that file with a CWM card, not put in the boot partition of your SD. And since you did that, you need to re-flash your latest ROM on SD to correct your mistake. (I will edit my instructions to make it a little clearer that you use CWM to flash that file.)
I got NC stock ROM to see my SD card partition by following item A10. That is most excellent and thanks again!
Unfortunately, I no longer see the boot partition when I attach NC to my computer whether NC is running off stock ROM or CM7. My guess is that this is due to my failed attempt to flash from my CM7 SD card yesterday. Am I right?
I thought I could reverse that by copying the update-stockemmc-vold-fstab-return-to-stock.zip file to CM7's boot (and then booting to the recovery mode) but that seemed to have nothing.
If I understand your previous message correctly, I should re-do my entire SD card but... I have already spent a few hours downloading and customizing the Android apps. Is there a way to preserve all that before Win32diskimager destroys the contents of the SD card?
Is there a way to manually mount the /etc folder from a unix prompt and alter the file?
Does it even matter if I don't see boot while I attach NC to a computer? Are there any caveats to 'let it be'?
Questions, questions and more questions...
That leads me to the obvious question, is there a book that explains Android to someone who is not interested in programming it but wants to understand the architecture and design of the OS (and custom ROMs)?
Thanks for being patient with all these n00b questions.

I got NC stock ROM to see my SD card partition by following item A10. That is most excellent and thanks again!

You do not need or want to re-set up the whole SD installation. Just put the same CM7 zip file back in the boot partition and boot to SD recovery. It will put the correct vold.fstab back on the SD. You will not lose any settings or apps you have already set up. (And putting the return to stock zip there was also the wrong thing to do. The vold.fstab for stock and CM7 are different. But don't worry, it will fix that too.)
You are not supposed to see the boot partition on the PC when you plug the nook in with the cable. You are only supposed to see 'emmc' and 'sdcard'. Under the original setup, your stock system thought the boot partition was 'sdcard' and that was why you saw it on your PC. Since you modified stock to see partition 4 as 'sdcard', partition 4 is what the PC sees, not the boot partition.
Most people have to physically take the card out of the nook and put it in the PC to see the boot partition on the PC. If you don't want to do that, use my script in item B4. But since you are on CM7, you will not be adding many things to the boot partition to install with SD recovery in the future. So it is probably best to leave things be.
And I don't know of any books to help you.

That is excellent news!
A bit of playing around with Astro tells me that I was wrong about seeing the 'CM7 SDCARD' partition when I was on CM7 ROM. I am only seeing the boot. Anyway, I am going to flash the CM7 ROM again and I am hoping it would fix everything.
Also, yes, I can see the boot partition when I put the SD card directly on my computer but I was also able to see it when I hooked up the NC to my computer via USB before I did my unintended tweaks but... I'll survive.
I'll be back after I flash. (Famous last words??)
Mission accomplished!
Thanks again for all your help.
For future reference after you alter stock's fstab... all you have to do is:
mkdir /sdcard/boot (only have to do this one time)
mount /dev/block/mmcblk1p1 /sdcard/boot (do this every time you want to put something on the boot partition)
put anything you want on boot partition in /sdcard/boot

Yes, there is one big advantage to using that method. I think it allows the boot partition to be seen not only on the nook, but also on the PC when you plug in the usb.

We could probably come up with a symlink to /dev/block/mmcblk1p1 to /sdcard/boot and avoid having to mount it everytime as well.

Thank you Dizz, your suggestion got me to thinking and I was able to come up with an init.d bash script that does the trick. I just temporarily mounted sdcard and created the sdcard/boot directory and the mounted the boot partition to it, then unmounted sdcard so it could be mounted again by the system later in the boot sequence.
The only problem is now sdcard will not mount on the PC using UMS mass storage. Must be because of having a second mount within the mount. But it does mount with MTP. But that may be acceptable. I will test some more, including using Goo Manager tomorrow.
EDIT (6-21): Goo Manager works. But I think I have figured out why sdcard is not mounting in UMS. Once it is mounted in my script and the boot partition mounted under it, it cannot be unmounted. And since it cannot be unmounted, it cannot be mounted later by the system as vold. If it cannot be mounted as vold, it does not show in UMS. For now I think I will leave it as I have it in Rev 2 of my script (symlinking to the root directory with full r/w permissions). If people want to see the boot partition on the PC, just use my modified for CM9 NookColorUMS available in my tips thread.

Help!
When CM7 is running, my computer is no longer mounting any of the partitions when I connect NC to my computer via the USB cable.
If the NC stock ROM is running, my computer mounts all three partitions (MyNook..., boot and CM7SDcard) but calibre is not recognizing the external partitions for transfers.
Further, when I boot to my NC stock ROM, I am no longer seeing my SD card's contents in the NC's library.
This may have something to do with the fact that NC stock ROM seemed to have updated itself to 4.1.3.
Should I re-run the scripts again or am I missing something else?
When it was updated to 1.4.3, you lost the emmc mods. Just re-flash my zip with the CWM SD. You may have lost CWM on emmc too.
On CM7, you have to select the turn on storage button after you plug it in. It is not automatic like stock. Pull up the notification area and touch the turn on button.
Darn, I forgot about that 'USB' option under notifications. Enabling it allows me to find the partitions. I will run your scripts again when I find a spare mUSB card.
Thanks again for your help!

Thanks for your speedy reply.
I have some further questions though:
1. which 'recovery' do you mean and where will I find Titanium backup and tytung tool?
2. I have downloaded the paragon software to copy the sd card contents which I will try to do now. However, what are the 'normal' methods used to resize as I mentioned in my previous post that the ext4 partition seems fixed when using the mini tool partition software?
TIA,
Geoff.

Robbie,
I have put the sd card into the slot on my computer (which is a year old HP laptop) and also tried in a USB port but the Paragon software is not recognising the card at all, with only the c drive being shown. However, I am able to see the contents of the fat32 partition of the SD card through explorer as normal. Am I doing something wrong??

Which recovery did you use to install the rom? does it have facility to backup ext partitions? I know macs18max edited SDrecovery can do this from the first post here http://forum.xda-developers.com/hd2-android/nand-dev/nov-17-2015-kernel-3-0-101-t3251438 others can too.
titanium backup can be found in play store, free and paid versions. haven't used it myself for a while and only used free one. people on this forum swear by it though.
tytung's NativeSD backup might have to be searched for, I'm afraid.
Don't know why your ext partition is not showing up. What rom(s) are you using?
magldr or clk?
Sounds like you will have to use a backup method from the phone as opposed to pc, to store the contents on your FAT partition, then move/copy them to pc.
does this make sense?

Thanks again Robbie. Tis whole thing gets wierder as follows:
I'm using Nexus HD2 Jellybean-CM10_V1.3a as the rom. In the recovery directory of the SD card there's the Jellybean rom as mentioned, clrcad (dated 8/7/2010, haret, initrd.zip, startup text document & zImage (dated 5/9/2012).
There's also a NativeSD directory with the same files as the recovery directory.
Running Haret from the recovery directory takes me to 4EXT Recovery v2.2.7 RC5.
It also shows: E: can't find misc
E: failed to find "cache" partition to mount at "/cache".
In the info section it lists the sd-ext partition ext4 1012MiB free 135.5mb, sdcard fat32 14175 MiB free 8.0gb.
Attempt to backup fails as can't find cache partition, boot, recovery logs on E:
I loaded the Paragon software on my newer laptop but no ext partition was found. I then loaded the Paragon software on an older laptop and hey presto the partition was there. I tried to back this up on the pc but had repeated problems with files not being read. Then suddenly the ext partition disappeared on the pc but phone booted into Android-phew!.
I tried on the 1st pc and suddenly it recognised the ext partition. I tried backing up the partition but again had read problems. The fat32 partition backed up without 1 error.
So where do I go now? I don't want to loose the data in the ext partition but don't seem to be able to backup. Any suggestions welcome.
Geoff.

All the above is normal for NativeSD, your sdrecovery doesn't allow for backing up the ext partition

perhaps paragon wasn't the best choice for backing up. Try the recovery linked-to above, put it on your sdcard and run haret from its folder (you might have to change the folder name so that it is not the same as your other recovery folder). then select backup, then scroll down to sdext, tick it and swipe, it should copy to your FAT, and it seems you have plenty of space there. I haven't tried this backup method, which is why I said use 2 methods to backup. the more the merrier.
There are free sms, phone and app backup applications such as superbackup in playstore.
There was also a way to copy the whole sdcard as an image, partitions included, I will have a look for it.

Robbie thanks again.
I downloaded the recovery folder from your link but there's only 2 files in it namely initrd.gz and zImage, there's no haret. I have copied the haret, clrcad & startup text files files from the old recovery directory but it just hangs on running haret.
Geoff.
Sorry Geoff, I am not giving you very good advice. That recovery has a 3.0 kernel in it, and won't boot from haret. Am working ATM, will reply later.

Hi again Robbie,
I have good news and bad!!
I managed to eventually get the Paragon software to recognise the ext4 partition on my new laptop. What's odd is that the ext4 partition is listed under the name of the c drive. I then unmount and remount the ext4 with a new drive letter and I can then read/write. So having managed to mount, I was able to copy off all the files from the FAT32 & ext4 partitions to my hard disk. That's the end of the good bit.
As its 3 years since I did the last Jellybean install, I'd forgotten what to do and kept seeing posts about magldr and custom radio roms. I tried to boot into magldr on the phone while doing the sd card backups but it wouldn't go into it. I had assumed I must have installed it when I did the original SD rom install and I then wrongly assumed I needed to reinstall the HSPL4 and custom radio roms to get it on again. The former was ok but the latter caused the phone to hang on reboot at the HTC logo. At this point I went to the bootloader screen but after having the 4 colour screen I then got the white screen with blue writing for updating the rom from an sd card (there must have been an unzipped rom on the card). I mistakenly hit the install rom button and this erased all the phone's data before I'd had chance to use SD Backup, a programme I hadn't bothered using since long before I converted to Android.
I then looked back in my old bookmarks and came across a facebook guide to the Native SD installation which didn't mention magldr at all and it was at this point that I realised I'd not previously loaded it on the phone, although I did eventually manage to get it on after downgrading the HSPL to 2.08 and successfully flashing the custom radio only to be permanently booting into magldr-so I again reflashed the stock rom to get rid of it! What a waste of time!!
Having backed up the sd card partitions, I erased the partitions and made a new ext4 of 3gb and copied back the files to both partitions. I tried to boot the haret in the native SD folder but the phone hung at the HTC logo and then rebooted itself back into windows. I tried installing the jelly bean rom as an update using ext4 recovery but no joy. I tried wiping the ext4 partition and reformatting with EXT4 recovery then installing the rom as a new install which then booted into Android ok after which I overwrote the ext4 files with the previously saved ones. Now I get a boot into the CyanogenMod screen but no further even after waiting 30 mins. I also tried using NAtiveSD onetouch recovery to try and make a backcup of the old system and then restore over the new install (but not the boot files) but again I just get the hung CyanogenMod screen.
So do you have any idea of how I might get a successful boot with my old data? Perhaps I'm missing something else in the overwrite/restore process but I can't see what.
Any further help would be grateful-perhaps you have forum contact who might be able to help as well.
TIA,
Geoff.:crying:
