Help Request- Partitioning a 8GB SD Card for Mytouch 3g, Have Cyanogen 4.0.2

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.

...
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
http://theunlockr.com/2009/08/22/how-to-unroot-your-mytouch-3g/

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.

[PROBLEM] Clockwordmod recovery issue

hello,
i am havin annoyin issue with clockwordmod recovery 2.x.x.x.x, it doesnt see new files on sd card.. i have tried formating sdcard from recovery but it didnt format it at all.. next i formatted sd in windows, but still.. when i log into recovery it suppouse to show the files i've uploaded onto sdcard which were; cm7, nightly 40, new radio, gapps.. but instead it shows the old files which are not on the sdcard.. the problem is more annoying because i ve notticed that after formatting system, wipping cache etc.. so now i have only acces to broken? recovery and my wf gets bootloop all the time.. please help is there any way to flash the new cm7 from pc or somehow fix the sd card and flash new cm7 and fix the recovery??
i have searched @ google but i found notting..
please help ; /
cheers,

Have u tryed using unrevoked again n updateing with Rom manager
Do u have another SD card
Sent from my HTC Wildfire using XDA App

i cant use unrevoked and rom menager because my wf doesnt load os.. i was tryin to put update.zip and load it from sd card but it says "cant open E:/sdcard/update.zip (bad) installation aborted.", ive load even file as pc49img.zip, in bootloader it says it's parsing and it looks like everything is ok but still have no updatec cmw ;/.
and no i do not have another sd card ;/

Surely borrowing an SD card from some of your close ones shouldnt be an issue? Anyway, did you try using an RUU to get back to the default state?

i;ve tried to use ruu, it only sees my phone while the htc logo but it says it's not enough charged.. i think ill try to wait until green led comes up and try it again ;/

Sounds like you might have partitioned your card, and now are looking at two different partitions, one from windows, one from recovery. You could try repartitioning it from recovery, to make sure that you only have one FAT partition and one EXT and that they are in the correct order.
Mine has its FAT partition on p1, and ext2 on p2.

hey mate,
could you guide me how to do it? in recovery i have;
unmount system
unmount data
unmount cache
mount sd-card
when i click on mound sd-ext it says "ERROR MOUNTING SDEXT:!"
;/
i took off the sd card and formatted it then i mount it into the device and tried to choose zip file but it was unmounted in options so it didnt show me any files, next i've mounted sd card and left sd-ext unmounted and againt its the same, it shows me the old files which dont even exist anymore, i guess it maybe something with partitionin, but how to do it? could you guide me how to make one fat and one ext ? like u have? thx in advance

I partitioned mine from a linux PC with an SD card reader attached, but it should work from recovery as well.
From the Clockworkmod recovery menu, choose advanced and then partition sd card then choose the size you want for the ext partiton, then the size for the flash partition (if any). That should set them up correctly in the correct order.

Questions/Problems don't belong in the Development section <---please click link and read....moved to general...

i've wipped cache and during wippin it said that there is no sd-ext partiotion ; / it's something wrong with clockwork but i have no idea what.. it shows only the old files that i've loaded on sd before flashing with cm7 rc-2 ;/ the weird thing is that i remember that i updated cmw do newest 3.0.5... (something like that - the orange one) and it worked fine but next when i log into recovery it shows the older version oO
i successfuly manange to update cmw, i used adb in that purpouse and now everything works fine

Clone SD card (with a2sd on)?

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?

[Q] Can I have partitions that can be accessed from both NC Stock and CM7 on SD 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.

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!

Help With MAGLDR Install

Hi Guys,
Back in April 2011 I bought a HTC HD2 phone off eBay and followed the instructions at http://forum.xda-developers.com/showthread.php?t=893948 and installed Android. I can't remember the ROM I installed.
Anyway, I now want to upgrade the phone to ICS.
I have gone to http://forum.xda-developers.com/showthread.php?t=1434860 and downloaded the ROM NexusHD2-ICS-CM9-HWA_V2.4.zip
Under the "Instructions" section, I clicked on mskip's guide which takes you to http://forum.xda-developers.com/showthread.php?t=1044830
This says that it assumes that MAGLDR is installed and if not, follow the guide at http://forum.xda-developers.com/showthread.php?t=893948
which is the thread I followed back in April 2011. I therefore assume I have it installed but not sure how to check. I decided to try to install it again, but I can't get WMDC to see it when I connect to my PC but I have downloaded HTCSync which can see it.
How do I get WMDC to see my phone so I can do an install (my PC is Win 7 64 bit) or how can I check it's already ok to go because of my install of the ROM back in April last year?
Also Since my PC is probably not the same as it was 15 months ago when I did the above flashing, I tried to install Radio. The link on that page doesn't seem to work, but I went to the link from my previous attempt ( http://forum.xda-developers.com/showthread.php?t=893948 ) and downloaded that Radio (Radio_Leo_2.15.50.14). I guess I'll need to install this at some point.
As for HardSPL, I somehow ended up at http://forum.xda-developers.com/showthread.php?p=5279234 but my phone's exactly the same as the screenshot at the bottom of the first post. I then ended up after some searching at http://forum.xda-developers.com/showthread.php?t=609477 and downloaded HardSPL 4. Since I can't sync using WMDC, I ended up successfully installing it by following the note at the bottom of the install instructions which read "You can also install HARDSPL by entering Bootloader mode manually, then running the HSPL4.exe program once you see 'USB' at the bottom of the tri-colour screen."
I think I'm starting to get lost trying to follow all these different threads etc and really would appreciate some help.
All I want to achieve is a nice ICS install that's stable and user friendly.
Thanks in advance.

1- You already have HSPL.
2- To check if you have MAGLDR (when booting up phone, hold "END" button) If a multi-option screen appeared, you have MAGLDR.
3- Next upgrade your radio, do so by booting in the bootloader and update normally (WMDC will not see your device, but you should be good to go as long as "serial" changes to "USB" on your phone.
4- Update/install CWMR.
5- Flash your ROM via option 8. AD recovery.

If you followed the original older guide, then you have all of the prerequisites and have installed the DFT Desire ROM. Just follow the second MSkip guide to flash CWM, repartition your SD card and flash NexusHD2. Just use the correct partition size which should be mentioned in the OP.

At http://forum.xda-developers.com/showthread.php?t=1044830 I've got down to point 3. FLASHING A CWM (CLOCKWORK MOD) ROM and have done up to point 2 - wiping data/factory reset
Currently my ROM (NexusHD2-ICS-CM9-HWA_V2.4.zip) is on my PC and the phone doesn't show in Explorer, so I read a bit further down where it said:
HOW TO COPY FILES TO YOUR PHONE
NOTE: This can be used to copy music or data across to your Storage Card and for copying your CWM Rom (with .zip extension) to the Root of your Card for flashing
1. Connect your phone to your pc via the USB Cable

Other than removing the card and putting it into a reader and plugging the reader in to the PC, how can I get the phone to Mount USB?

I've never actually tried to mount USB Mass Storage outside of running a ROM, I always use an SD card reader so I'm not too sure why it isn't mounting. Have you tried the USB Mass Storage option in the MAGLDR main menu instead? Also, be conscious of how you use your phone whilst in MAGLDR and CWM, as you can't charge the phone via normal methods. It shouldn't be too bad, as I've found battery drain in both to be minimal, but at the same time don't just leave it on for a few hours whilst you wait for a response or a download or something.

Thanks. As soon as I went to USB Mass Storage, Windows installed driver and showed it in the Explorer window. It apparently needs to be formatted first, so whilst I look around and find out what format I should use, I'll put it on the charger as I've had it sitting at the menu option for the past 12 hours or so whilst waiting for a response.

Unless you mean an external battery charger, if you try to charge it it will just boot into magldr. I assume you mean which format type for the SD card right? That would be FAT32, and you can later create an EXT3 partition in CWM

Yep, an external charger.
I had found via a quick search that FAT32 seemed to be the best. Out of curiosity, I've already done point 2 at http://forum.xda-developers.com/showthread.php?t=1044830 so when Windows does do the format, I assume it will be the remaining partition that was created (leaving the 1024M partition alone)? If so, do I need to manually set this 1024M partition of EXT3 or would that have been done as part of Step 2.

There is actually a quick way to check. In CWM, go to the wipe data option and wipe data. If the sd-ext is present, it will format it and you will know. If sd-ext is wiped then it will say "no sd-ext detected, skipping format of sd-ext" or something similar.
But when formatting the card using windows, it doesnt really remove the sd-ext partition. Just cleans the Fat32 partition

I went into "Wipe Data/Factory Reset" option and the following came up:
-- Wiping data...
Formatting /data...
Formatting /cache...
Formatting /sd-ext...
No app2sd partition found. Skipping format of /sd-ext.
Formatting /sdcard/.android_secure....
Error mounting /sdcard/.android_secure!

So I went back to the USB Mass Storage option to let Windows do the formatting. It only allowed FAT, NTFS or exFAT but no FAT32 option. Selected FAT and it said that Windows was unable to complete the format.
I've gone back to the instructions at http://forum.xda-developers.com/showthread.php?t=1044830 and started again at point 1 but still no luck. I hope that re-doing point 2 doesn't mean I've now got 3 partitions.
Since that didn't work I was having a look at the "Mounts and Storage Menu". Should I perhaps select "Format /sd-ext"?

Hi guys
Any further ideas on how to format my partition? Do I need to choose mount /sd-ext or format /sd-ext ?
Thanks

Hi Guys,
Whilst waiting for a reply on my USB issue, I thought I would try a few things.
I ended up getting an SD card reader and plugging the SD card into Windows to see if a format would work that way. It didn't.
I then opened Windows Disk Management system and it said the whole card was unallocated. When I right clicked on it, I was offered to create a "New Simple Volume". Since I'm only using a 1GB card, the maximum disk space in MB offered was 967 which I chose (basically the default).
In the "Format" section of the wizard I formatted it as FAT32 and left allocation unit size as default. I removed the tick from "Quick Format".
Thinking this was the solution to my problem, I put the card back in the phone. I also assumed that I would need to re-do everything at http://forum.xda-developers.com/showthread.php?t=1044830
Unfortunately I can only get to point 3.2 where I do a factory reset.
Is it possible that Step 2 where I partition the card is stuffing something up? If so, can I skip this part and just do Steps 1 and 3?
Thanks in advance.

OK so you're stuck on point 3.3? I.e. Actually locating the ROM and flashing it? I think what you're doing is copying the ROM over then partitioning. What you should have done is partitioned then copied the ROM over, as partitioning completely wipes the card.
Another possible problem with your method is that you only have a 1GB card, so if you select a 1GB EXT partition then you have no FAT32 partition, and as a result you won't be able to flash the ROM. Try using a 256MB EXT partition instead, and then flashing. Hopefully it will all work fine after that.

How embarrassing is it that I didn't pick up on this. I was blindly following the instructions and set my partition to 1024M when I've only got a 1GB card. Just excuse me for a moment whilst I slap myself up the side of my head.
OK, I'm back. Rather than reduce the size of the EXT partition, I might buy a bigger card anyhow to allow room for photos etc. I will let you know how I go tonight.

Hi Guys
I purchased a 4GB card today and just got home and the install as per the instructions ( http://forum.xda-developers.com/showthread.php?t=1044830 ) went without a hitch.
Amazing what you can do if you don't try to create a partition bigger than your SD Card. Still can't get over how I missed seeing the obvious.
Thanks to all the posters for your help.
