I lost my sd card data flashing a rom. Could not mount it even thru recovery. Got a card reader, but it won't format it.
Using Mini Partition Tool to troubleshoot. I am not at a point where it shows three partitions. The main 16gb unallocated, logical. The ext3 unformatted 500mb, primary (think I did that by mistake when trying to recover partition). And a 32mb unallocated, logical. All zero used memory.
I need to get back to one partition allocated, primary. Then I can get sd data back on it and reformat thru recovery.
Again using Mini Partition Wizard
Any help please!
OK,
I got it repartitioned as primary and formatted, bu sd card from pc now.
Hope phone recognizes it.
Will update, if I need further help.

If you want a good program to format your sd card, try SD Formatter.
Download and install that, plug in your sdcard into your sd card reader and format it.
Choose Full Erase On (if possible) and Resize On. It will format your sdcard to factory default and that means even the ext partition will be gone too.
Well, all transferred. Still won't mount. Says can't mount either of the dev/blocks mmcb1k0p1 and mmcb1k0.
Staus bar says sd card damaged.
?????
musashiken,
Thanks, typing while you posted. Based on my last post should I still do that?
Ken
Yeah I think you should try to reformat again with the program I suggested, as that will full format your sd card.
Once done, put your sd card back to the phone and create ext partition in recovery.
At work now but will be working on it.
Thanks
Ken
musashiken,
Thanks, appreciate all your help
That program worked, and I am back up and running
Ken
Glad it worked for you. My sd card kept giving me problems and I have to use this every few rom flashes.
I have a similar problem. I installed a new 32 gb SDHC card in a CDMA Hero running Cryogenmod. All was working well for about 10 days, then I got an error that no SD card was found. I had the original card and tried to get to the Clockwork recovery, no luck. Finally, through Rom manager, (flash alternate recovery to Ramon, then back to Clockwork, I was able to boot into recovery.
I still cannot format the new SDHC card, through Recovery, Windows 7, or the Panasonic program listed above. The Windows format option sees the card as a FAT 121mb card, so does the above program. Is this new card toast? It came with a lifetime warranty from Kingston, but I am mad that it did not make 2 weeks.
Any help would be greatly appreciated.

If sdformatter did not work it may be bad.
I always had good luck with it.
Did you have all options set per instructions?
so i either don't fully understand how images work in the SDCard itself (not on the nook), or i did something wrong and don't know how to fix the card, but at any rate, i managed to burn a 128meg image onto my 8gig sd card, didn't like the image, and now can't figure out how to get the card back to a regular 8gig card!
would love some direction. tried to search but must not be using right keywords.
didn't see any kind of format or clear option in the winimg program we're using.
thanks!

On your Nook I believe you can go to Settings, Device Info, Mount the SD card if it's not mounted and then format it. It'll erase it and you'll have a blank SD card. If you're going to put a different image on the card I don't know if you even need to bother formatting, but I' not sure about that stuff.
does the nook format work differently than a computer format? because i burned a 128meg image onto an 8gig card and now even a computer format won't get the whole 8gigs back... just the 128 megs. it's like it's got invisible partitions on it or something.
Partition
Try EASEUS Partition Manager to change the partition size/format card.

byproxy... here is the easy way...
1) Go and download "EASEUS Partition Master 7.0.1 Home Edition" --- just google it (the home edition is free and downloadable)
2) Put your microSD card into a card reader and plug into your computer
3) install EASEUS onto your computer and run the app
4) Once app is started, located your microSD card amongst the list of drives listed
5) select each one of the partitions on the SD card, and delete them individually
6) Once all partitions are deleted, make sure that you are still selecting the microSD card, and select the option to create partition (it may just say create)
7) Make sure you select FAT 32
8) Then select FORMAT
9) Lastly, click on APPLY and it will do all the things above. So in short you select all the actions that you want... and only in step 9 will it execute all those actions.
Please make sure that any changes you make are to the SD card and not any of your other drives. Last thing I would want is for you to accidentally format your Computer, NAS, or your non-SD card. =)
Enjoy...
sweet. exactly what i was looking for. thanks gents!!!

OK, but isn't it easier just to do it in the Nook or am I missing something here?
...worst case there's a low level SD card formatter from Panasonic (IIRC might be Toshiba) that will do a complete low level format and has recovered uSDs for people using them with Nintendo DS dev carts...
A Google search should turn it up, or a thread on a DS site which might have a link to it. It'll be a little windows program...
(I believe that windows and most devices just do sort of a quick format of the uSD, and so can't recover from some problems like re-partitioning of the card... so monkeying around with a partition editor and assigning the card to be one big partition then re-fromatting under windows or some other device MIGHT work as well...)
[EDIT]
oops, I see post #5 has the re-partitioning solution as well... another way to do it would be to backup an image of the card BEFORE burning something like autonooter on it then restore that original image to card once finished with whatever you were trying out... it's what I did when I tried autonooter w/my old 128MB card, in linux in my case a
dd if=/path/to/sd/card of=./somefilename
dd if=./autonooter.img of=/path/to/sd/card
then later
dd if=./somefilename of=/path/to/sd/card
sd card path under linux is likely to be /dev/memc<device ref characters?>
You should also be able to do this under windows with the utility recommended for windows users to use with the autonooter image, as I'm guessing that it's just a GUI wrapper and a windows compiled version of the dd utility...
[/EDIT]
Varying opinions

Some believe that there are issues with formatting on Nook... depending which ROM you are running. The surefire and safe way, is to do it from a PC.
Nook should format, but may not partition correctly.

No, the Nook will format the *device* and not a partition, so it always works. But you don't want to do it if you've installed NC or HC to eMMC.
If you're using Stock rooted, just boot without the card in the device, put it in, format. Done.
Or if you're on a real os just format the device... mkfs.vfat /dev/sdX
How do you remove the burned custom ROM image off the sd card? I tried formatting the sd card but its still there. I have a 4gb card and its using up the whole space.
where did you try to format it?
If you're using windows, you can just right click the drive in My Computer and click Format. Do a full format, it should take 5-10 minutes. I've had to do this 2 or 3 times since I got my nook and worked perfectly. Alternately, if you're running stock ROM on your nook, put it in (after it's booted up) and go into the settings and Format that way.
You should also be able to format the mSD card directly on the NOOKcolor. Is your NC running a custom ROM or stock?
I use a program called minitool partition manger for windows, you can delete all the partitions and then stick the sdcard into your nook and have it format it...
first time I did the method through windows, it did not work. The third time around allowed me to reformat everything. Thanks for all the suggestions.
Sorry if this is in the wrong area. I was going to root my NC so I followed the directions and formated my 8gig sd card then ran autonooter2. The card show the correct files on it but now Windows reports the capacity of the card as only 39 megs. Is this normal....and will the capacity return if I reformat the card? I am using windows 7.
Thanks
Yes, it is normal,
and yes it will return full capacity when you reformat.
Awesome....thanks!
I was only able to reformat it to the correct size by formatting it from the Nook setting menu. It wouldn't work for me on the PC, it would just wipe it.
The size is never changed, but when you flash images to it the card is partitioned.
Windows can't see all of these partitions so it looks smaller.
It can be restored on the pc you just have to know how.
You can use the Partition Wizard Mini Tool which is free here at partitionwizard.com.
Hi
Please respond to the following. I tried a lot to look the answer to my problem in the forums, but could not find it (or did not get the right forum)
I dual booted my NC with CM7.1.0. It was working fine without any problem, but suddenly stopped entering into the main screen. Whenever i on the nook the Cyanogen loading ... screen comes and then screen flashes and turns lit black.. the NC is not off but it does not reach to the main system. I tried to use update the CM by copying a new file to usd, but it did not let me do so.. computer hanged. I do not want to format it as it has some .xls files in documents folder in the 4th partition of usd. Can someone please tell me how to extract those files using computer's sd car slot ( I can not use nook usb option as it is not booting CM) and how to recover the older working condition.
I assume you have stock working on emmc. I have a flash file that you can temporarily flash to stock to make it read the fourth partition of the SD as 'sdcard'. Go to my tips thread linked in my signature and item B3 in the second post (last paragraph). It tells you how to modify stock to read that partition. If your stock is rooted, you can just edit the file yourself. If not rooted, you need to flash one of the files attached to the post. Instructions are there. After retrieving your files you can revert stock back to normal by re-editing the file or by flashing a second zip, or just keep it that way and use partition four for both systems. Then you can start over with your verygreen SD and reinstall CM7.
could not get it

We'll take this one step at a time. Do you have stock nook still on your internal memory? And if you do, is it rooted or just virgin stock?

Thanks for being so patient. I dont think it is rooted and the stock nook is touched as i follow a link provided in this forum to boot usd and dual boot nook without losing warranty to install cm7 on a usd.
When i use boot the nc, i see following responses
1. boot without usd: boots to original nc, all files and applications are there and work perfectly fine.
2. boot with usd without going to boot menu: cyanogen loading banner shows up and then screen flashes. .then a lit black screen .. nothing happens after that
3. boot with usd and selecting emmc in boot menu: boots to original nc but hangs at home screen
4. boot with usd and selecting sd (external storage) in boot menu: cyanogen loading banner shows up and then screen flashes. .then a lit black screen .. nothing happens after that

Your SD is definitely messed up. You will need to reinstall after we get your file saved that you want.
You will need a spare SD card that you can put my bootable CWM recovery on.
Go to my tips thread linked in my signature and download to your PC three files attached there. The one that starts CWM... and the two that start update-stock...
Extract the CWM zip. It will have a 200Mb .img file in it. Burn that to the spare SD just like you did when you made the verygreen SD. Once that is burned and you can see it on your PC, copy the two update-stock... zips to it.
Remove that SD from the PC and put in the nook. Boot. The CWM menu will come up. Select 'install zip from sdcard '. Then select 'choose zip from sdcard'. Scroll through the list and pick 'update-stockemmc-vold-fstab-modified-for-partition4.zip'. Then confirm the selection. It will flash the zip. Remove the CWM card and reboot to stock.
Insert the verygreen SD and you should be able to connect your USB and see partition 4 on the PC as 'sdcard'.
To return your stock to original after retrieving your file, just go through the process of flashing the other update file with CWM. But most people like leaving it modified so that they can always use just one SD for both systems.

I did exactly same, but could not see partition 4 on the pc as 'sdcard'. I see two drives 1. mynookcolor ( i can access all files in it), and 2. a removable disk drive I:/ ( that i can not access). I do not see my files (see pic below) those are on the 4th partition of sd card.
You need to mount the card in settings. Go to settings, device info, SD card. And choose 'mount SD card'.

If it says unavailable and the first two are greyed out, that means it is not mounted. Pull it out and put it back in... wait you had the cable unplugged when you checked that didn't you? You should have.

What I am asking is with the USB cable removed, what does the settings show? If you remove and replace the SD with the settings window open, is there any difference? You say it detects it, how do you know that?
Edit: I have been searching for a solution for you. There are two ways to see those files with your PC. To view it in Windows, you must make several complicated changes to your drivers. I'm sure you do not want to do that. The other way is to use Linux. It has the ability to see and mount multiple partitions on an SD. You can either find someone who has a Linux system to do it for you or you can make yourself a Ubuntu Live CD that you can boot with your PC. None of these options are easy, which is why I was trying to do it the other way on your nook.
I don't know why your system is not mounting that SD properly. Even if those changes I had you make were not there, it should at least mount partition one on the nook.

The card is not written correctly... if you format it in the nook... you will see it on your computer... then you can remove it... and try writing the uSDcard image again with win32diskimager

Dizz, he was trying to figure out how to get his data off of partition 4 before he reformats and starts again. I was hoping he could do it with the nook, but it is not reading it. I had him modify emmc so it can see partition 4, but no luck here. Do you have any ideas?
Sent from my Nook Color running ParanoidAndroid and Tapatalk
I just had another thought. Put the card in the PC and open with your partition software. Delete partition one, two and three. Then maybe windows can see partition 4, since it is now partition one. You may have to move it to the beginning of the SD, but I don't think you have to.
Edit: I was able to test this on my spare SD card with the EaseUS partition program and it works. Be sure to give it a drive letter.

No, your installed apps are stored on partition 3. But if you bought them, google lets you redownload and install to as many devices as you want, as long as you are logged in to your Google Play account. What you will get back is things you had stored on 'sdcard' (pictures, books, music and other files like your xls files you wanted, what you saw in that screenshot you posted.)

I had thought of this before I commented about the SD being not formatted correctly... should only have to delete partition 1 ("boot") since windows should use the first fat partition....
However...
Since the nook doesn't show "unmount" or ""sd card memory" active... it is certainly not reading partition 1 correctly.
He can flash my B&N 1.4.1 with SASD vold.fstab edits to see partition 4 (if it can read it) and transfer everything from that partition.
