That happened to me awhile back; I had to reformat the emmc partition to get it back. Here's what I finally did: http://forum.xda-developers.com/showpost.php?p=14572867&postcount=2. NOTE: you will probably get a different device than /dev/sde! Check before overwriting! This loses the former contents of /emmc.
I was getting a "Damaged SD Card" notification when I booted, and the filesystem on /emmc (aka /media) was corrupted and wasn't mounting at boot time.

thanks but it was on the 1.0.1 software version, not cm7 where I couldn't se the storage. I remember now that when I tried to format data it woldn't work. do you think I should try doing "the dummies guide to fixing my nook wont boot" again

can someone please help me!!!!!!!!!!!!!!

[Q] Dumb CM7 Rooting problem

Hi, I have a nook color and an 8gb SD card. I've followed the posts to get winimage to write the generic-sdcard-v1.3.img written to my card and installed on my nook. However, when I shutdown the nook and put the SD back in my PC, there is no \Boot partition, and windows(xp) says the card is not formatted. What on earth am I doing wrong??
Thanks.

Put it back in the Nook after you have booted into CM7 and format it with the Nook. If you have a camera that takes micro SDHC cards you can probably format it with that as well but will probably want to delete any folders the camera creates later.

Well of course! How stupid am I?? Jeesh! THanks.

OK maybe I'm just missing something big.
After I install the SD card in the Nook with the CM7 upadate on it, the SDCard is modified such that when I remove it, the PC no longer recognizes the format. I get the card in my list of drives, but when selected it says "not formatted" If I choose format, it wipes the card and I can't boot to CM7 from it any more. I can't find a format option on the Bare CM7 image - just erase SD card -which still leaves it in a format that the PC can'd read to put the gapps on.
help??

Logical thinking, dr. wambo.
you have drive C which you install Windows OS on it, and then you format it, what do you expect?
In your case, "boot" MUST be there in order to work, if you format the card, it's gone for good. Question is why you format it after creating it?

Understood. My issue is that after I put the SD card into the Nook and boot the nook, it apparently reformats the SD card such that when I put it back in the PC, I can SEE that the card exists, but no files on it. If I check properties, it shows no free space on the disk (and none used for that matter.) So, I am unable to copy the gapps-gb-20110613-signed.zip file to the SD and restart the nook.
See?

A simple question, do you see the "boot" when your plug the card into your PC (running Windows)?

I do not. Windows explorer shows an SD card in the list, but when selected, it says the card is not formatted.
Card seems to boot fine in the Nook. I must be doing something really dumb. I was able to install honyecomb successfully using this card, but wanted the functionality of CM7. Darn, this just shouldn't be that hard.

Wait, if the card still "seems to boot fine in the Nook" then it means the "boot" is still there, it just Windows not seeing it.
On PC side, try to insertion and removal a few times and see what happens.
If completely nothing, switch to other Windows PC OR if you have the USB-SD adapter, use it.

I should mention that the nook boots fine off the card provided I don't Format it in the Windows box.
Have removed and reinserted the card multiple times into the Win (xp) box. No Joy. Tried a different machine and got exactly the same results.
This just can't be that hard!!

Are you using Windows PC or Linux?
Worst case, reinstall

Windows PC running. XP sp2. ADDITIONAL NOTE. After I winimage the SD card with the generic image, I do indeed have a \root partition. Once I insert it in the Nook and let it boot, shutdown, and I reboot, CM7 is installed and running from the card, but when I put it in the PC, the \root partition is no longer there.

Additional info. I've now tried this on 2 different SD cards and they both do the same thing.

Not sure if you're still having problems, but it's normal for Windows not to be able read the entire SD card after it's been imaged for CM7. There are I believe 4 partitions and it will generally only see the 1st (/boot). Additionally, it will sometimes only read correctly when using a USB card reader, rather than putting the uSD card into a built-in card reader in your PC (not sure why). Hope this helps.

Interesting...perhaps that's the problem. I'm using the internal SD reader on my laptop. I'll run out and get a USB reader and see if that helps.
THanks.

[Q] Access to bootable sd card from stock OS after 1.4.1 update

I have a nook color with dual boot from sd card. The sd card having an android 3.0 version.
After I got the 1.4.1 update, I noticed that I was able to access the sd card( the boot partition alone) from the stock OS boot of nook.
But now, dont know how, I dont see that anymore.
Was this a flawed update that was fixed or am I missing something.
Do help please.
I could really use the advantage of using the bootable sd card as a regular storage card when using the stock OS of nook. I prefer reading on the stock OS of nook.

Not sure why you're not seeing the SD card anymore, does it still boot?
SD card installs create multiple partitions on the SD card and the Nook will only be able to access the first one (boot). It should be accessible with any version of the Nook default OS.
You should have a media partition with a decent amount of room (1-5gb depending on NC version). That would give you more room than the 100-or-so mb on the boot partition.
Just found out that you can point the emmc install to see the "sdcard" partition of the sd card using the following info:

Yes, I can boot from it. Every time I plug in the SD card, the notification already says that it is safe to remove the SD card. In the device Info part of the setting, the "Unmount SD card" is already greyed, though it does say that the SD card is found.
It is however useful for me to know that the boot partition should always be accessible.
I did remove the SD card a couple of times without unmounting it first, could this possibly have corrupted the card?

Try to boot the uSD card (the one with Android 3.0 on it) and see what happens.
If it can, then it's good, if not, you can say it's corrupted.

Yes, I can boot from it. So I assume the card is OK
I plugged in other uSD cards and they get recognized fine. So I assume the Nook stock OS device recognition is OK.
I should probably recreate the boot partition as a last ditch effort

I had the same problem at first, but now I have mounted the correct sdcard partition that I wanted to mount.
I couldn't get it to work with editing the vold.fstab file at first. Then at some point after I manually mounted the correct partition through adb shell and edited the vold.fstab it now works.

[Q] Rooted:Where is my backed up image? How to get my lost sd card space back

So I am rooted w Nookmanager. I followed the instructions to the letter. I couldn’t be happier with the rooted Nook.
Since Im still a n00b at this..i have a few questions:
1. Which is the back up file of the original Nook, so that I can transfer it to my laptop and save it for any emergencies.
2. Also , my sd card (16gb) is only showing a fraction of the space when I insert into the sd card reader of my laptop. How can I get its full 16gb space back. Do I need to reformat it? If so, how and what software can I use?
3. I have some ebooks already saved in the My Files section on the internal hard drive of Nook. These books don’t show up on mantano reader (or other 3rd party reader apps I have installed).
a. I want to save my ebooks in a folder from where I can access them through Nook native reader as well as any third party readers I have installed.
Thanks for your help…. And long live XDA

Step 1. Insert microSD and connect your nook via USB.
Step 2. In windows explorer there will be a drive labeled backup. That's the partition Nookmanager created on the SD card.
Step 3. Open it up and copy the 2 files that are in there.
Getting your space back (after you copied off your backup):
Step 1. Start menu, search "partition", you should find windows partition manager in the control panel.
Step 2. Find the SD card which is now divided in 2 partitions, delete the partitions
Step 3. Right mouse click and create new simple partition, fat32.

I used HP USB Manger to reclaim the SD card space back by reforming it.
To get your backup file, please read:

I used Minitool Partition to format, delete the partition and then create a new partition . But in the process, I now have only 14.8GB. I lose 1.2GB. My original card was 16GB. is there anything I could do to get the lost space?

That's the full size. A "16gb" SD card is actually about 14.83gb because SD cards are sold by the bit. About 15.9 billion bits in a 16 "gb" card, divide that by 1024 three times and you get 14.83 something gb, and that's how windows see's it. Don't worry, you didn't lose anything.

Hiya, I know a bit of time has passed, but I'm having problems finding my stock back-up image I made.
I've followed the instructions as above, but explorer doesn't show the backup partition at all. I just have 'Nookmanager' and 'Nook' (the internal memory). I'm connected to the sd card through the nook simple touch (i.e. not through an sd card reader).
Any ideas how I can access the hidden back-up partition?
Many thanks in advance.

I don't think the Nook will present second and subsequent partitions on the SD card for USB mounting. You'll need a memory card reader; a cheap one from eBay will do the job.
The files are backup.full.gz and backup.full.md5 in the NookBackup filesystem.

I have a similar problem in copying the two Nook Backup files to my PC. Using a standalone SD card reader, I can see the 1.78 GB NookBackup partition in my MiniTool Partition Manager and in XP's Disk Management, but I cannot assign a drive label. The 64 MB NookManager partition is assigned a drive label, but NookBackup partition shows no drive assigned.
Since I cannot see the two backup files in Windows Explorer, how can I copy them to the PC?

I've tried both with a card reader and through the plugged in Nook. No joy either way. I looked at the card in Win7's Partition Manager and although it shows the extra space, it doesn't show it as being active or labelled or anything.
When I did the backup it took ages (nearly 30mins) and I was beginning to think it was stuck or something, but then it said it was completed.
I'm wondering whether it actually failed to create a backup. No sign of a backup or backup partition any where.
I think I might just format the card and hope I don't get any problems. Everything seems to be working ok.
Is it possible just to download someone else's backup or get the firmware off B&N again if I need it?

The memory card reader won't help as windows won't allow you to mount anything other than the first partition on removeable media. What you need to do is boot your Nook from the NookManager SD card and then plug it into your PC. You will then get two new disks in Windows that each show a single partition. The first disk will be the 64MB NookManager partition and the second disk will be the NookManager backup partition that takes up the rest of your SD card. If for some reason Windows doesn't automatically assign a drive letter go into the Windows partition manager and assign one. The key is you must be booted into NookManager. It won't work if you are booted up normally to read books.

Works well.
Having copied the original Nook partition to Windows, could I also backup the rooted partition from the NookManager backup menu? I would also copy the new folders on the SD Card. Or is there another way?

Yes. Note that NookManager's 'Backup' function will overwrite any pre-existing backup on the NookManager partition, so transfer your backup of your stock firmware first before you make a backup of your rooted firmware.

Ah... that sounds like it might work! Unfortunately, after spending several hours messing around with the sd card and the nook trying to make the other partition readable using partition manager and EasUS, I gave up and just formatted the SD card so that it was usable again. I did a data recovery sweep on the other hidden partition before-hand and managed to retrieve a .gz file of approx 49MB. I presume that is the back-up, but I couldn't retrieve the other file.
Oh well, fingers crossed I don't have problems :fingers-crossed:. At least the Nook was very cheap (£29) so it's not the end of the world if it things go bad.

49MB sounds a couple of hundred meg shy of a backup. You can try unzipping it with something like 7zip to see if its any good and worth keeping around but I doubt it. The other file you didn't recover is just an md5 of the backup and isn't necessary other than as a confirmation of a good backup.
You should take another backup of your Nook as it is now and keep it. That way you'll have a backup of your ROM partition so if things ever go too far south you'll be able to use someone elses full backup and then replace the ROM partition with your devices information.

What straygecko said. 49MB sounds too small, and even a non-pristine backup is worth having.

[Q] Basic question: Rooted with NookManager, what should I do with my SD card?

Hi,
I know this is fairly basic, but I'm really confused about what I should do with my SD card now.
I've read quite a few threads about different ways of rooting nook device, and so far I found NookManager is the most easy and understandable one (I'm a beginner ) And it is running perfectly on my Nook 2 at the moment.
For most of the root methods, they say one should use 'SD Formatter' to format the disk (i.e SD card) if the user is happy with the ROM, as in their methods the user should have already backed up before hand on the PC. However with NookManager, I did the backup during the root process in my SD card as instructed.
And I have realised that 'My file' is under the 'NookManager' disk, so I imagine everything should keep as it is in the SD card?
But I also notice that my 4GB SD card shrank to about 63MB when I wrote 'NookManager.img' in my card..
Plus NookManager loading page appears every time when I reboot if the SD card is inserted.
So I'm really confused now, could anyone help?
Many thanks !!!
To anyone as new as me and has the some question:
————————————solution——————————————————
By #2 straygecko from NookManager thread:
A 2GB SD card is fine. Even a 1GB SD card would work if you don't have a huge amount of books already on your NST. NookManager is a 64MB image so when you flash it you'll only see a 64MB SD card. Boot your NST with it and when you make a backup NookManager will make a second partition on the SD card using up the rest of the space on the card and put the backup there. Because Windows won't see the second partition with the backup on the SD card once the backup is complete and before you exit NookManager use your usb/microusb cable to plug your NST into your PC. You'll see two drives appear on your PC - Nook Manager and Nook Backup. Copy the backup off the Nook Backup drive. Eject the two drives on the PC then go ahead and root the NST and exit NookManager.
At this point if you put you put your SD card into your NST you will only see the 64MB NookManager partition. If none of the apps you want to load require an SD card you could just leave the SD card out of the NST and you'll still have room for books on the internal memory. But I found a lot of apps require the SD card and an SD card gives you room for oodles of books if you need it. If you don't have another SD card to use in your NST then you'll need to repartition and format your SD card. Put the SD card into your PC card reader and use a partition manager (Minitool Partition Wizard, Paragon Partition Manager 12 Free or your favorite) to delete the two partitions on the SD card and create a new FAT32 partition that takes up the whole card. To make my life easier if I need to go back to the backup I made a drive image of the SD card before I repartitioned it. Put the SD card back in your NST and you're good to go.

Thank you. I have just read it again. Obviously I missed out your important post when I first read it, as the thread is fairly long
I got my answer now, thanks again.

My 2 cents:
After many problems with the dates of files on the SD card mysteriously changing by a few integral hours I decided that I had had enough with FAT systems.
(FAT stores timestamps in local time, a recipe for anomalies.)
For many, this might not be an issue, but if you are using things that sync using timestamps, it will be.
See: ADB sync utility - adbsync
My solution is to use the ext3 filesystem on an SD card.
See: vold, using ext3 on SD, USB drives
