[Q] SD Card Unusable?

Good Evening XDA,
Today I received a Nook Color for the holidays (yay!) and rooted it very easily with Autonooker. Now, my problem is that I formated the sd card after I got the Nook to root, but when I try to use the SD Card it only tells me that 40 MB is available (from a 2GB Card).
Is my card completely useless now, as I am afraid to put it back in my nook in so that I don't get a constant rerooting happening, or is there a way to completely remove the image and get it back to its "full" 2GB?
Thank You.

Should just have you Nook on, Nook tools/settings, SD card. Theres an unmount button, hit unmount then the format right under.
Thats what i did to mine, or just throw it back on the pc right-click format.

Actually, that worked very well.
I didn't think this through, but since I wasn't botting up the device, it wouldn't have been booting from the SD card and instead just reading from it.
Got it to work, thank you.

Same thing happened to my SD card, however I used a 8G card. Now I removed it from my nook, put it in my pc to format it and it still tells me I have only 40mgs of memory. I was going to use the 8G card for extra memory on my nook for videos and music. Guess I can't anymore unless someone can tell me how to get my 8G of storage back on my 8G sd card.

Look at camm's reply above. Put your sd back in your nook, go to settings ==> device ==> sd then hit <unmount> and then hit <Format sd>. That will put it back to 8gb

I finally figured it out. On my nook that is. Would unmount the sd card and quickly turn it over to remove it. Was wondering why I could never get the format SD card to work on the nook until I unmounted and watched the screen for the ability to format the sd card became available as an option for me to use.
Just think I am too much of a noob at all of this.
Anyways, thanks.

Size-agnostic SD Card CM7 gets stuck while installing CM7

Hi,
I am unable to post in the dev forums. hence opening this thread.
I am facing a problem installing sd card bootable CM7.
I am refering to the folowing thread: [ROM][CM7] Size-agnostic SD Card image and CM7 installer for SD Cards. with updater: http://forum.xda-developers.com/showthread.php?t=1000957
I do the following:
1. Burn the 9M image (that would unpack into ~130M disk image)
2. Put the downloaded CM nightly build on the sdcard
3. Put the card in the nook color and boot
4. The nook boots to the installation process...penguin image in a corner and starts the process
However, it gets stuck at "Writing superblocks and filesystem accouting information".
I dunno if its stuck or not......because the cursor keeps on blinking.
Its been about 30 minutes and the screen stays in the above status only.
For information, I am using 16gb Kingmax Class 10 microsd card.
Any help will be greatly appreciated.......

Ummm... did you unpack the image prior to burning it to your Sdcard?
In addition it is not proven yet to work on 16gig cards, it has only been tested up to 8gig cards.
Edit: Others now have posted that 16gig cards do not work.

And Class 10 cards are known to have issue with Nook.

Hi Adude...Thanks for the update.
Have a small doubt...
I am able to install and run successfully, the sdcard bootable CM7 bt image...which is for 2gb card.
I, then, expand that partition to the rest of the card.
So is it the size of the card thats the issue?
Can this 'size agnostic' image be modified to write only to 2 or 4 gb and then we can expand the rest. I will like to ask this question to verygreen, but i still have some posts to go till I can paste in dev forums.
Thanks again for the info.......

Bumping an old thread, since I have the exact same problem, and can't post in the proper thread as well.
But I used a 2GB class 2 card( I think, it's a generic card that you get in the bundle when you buy a phone) instead, but got the same message.
Did I harm the card in anyway? Can I use it again for this procedure? Or do I have to reflash it in some way?

Generic Class 2 card. You answered your own question, it's probably too slow.

Pity, that's the only card I have lying around.
I'm very new to this so sorry for some very basic questions. But:
1. How do I restore the card to it's original state? I tried the HPUSBFW.EXE file that is in the link above(how to flash a bootable SD guide) but it says that I need admin rights even though I already am admin. Is there any other way to restore the card?
2. I have another generic 2GB from a Sony X10 mini pro, but no idea to try that then? What kind of SD-card should I buy? Since I saw that too fast SD cards have problem as well.

I also can't post in the dev thread and am having issues with this. I'm using an 8gb sandisk class 4 microsd card. I used win32imager to burn the agnostic iso file to the card. Then I clicked exit, unmounted the drive, and plugged it back in. Now the drive shows as a 115mb drive with 107mb free. In gparted it shows as 2 partitions, 1 as 115mb and another as unallocated with the rest of the 8gb. Windows can't see the unallocated one though.
So right now I'm stuck and can't copy the nightly cm7 build onto the drive. Anyone know why it formatted it like this and what I can do to fix it?
Here's an image of what I'm talking about:

107 MB is enough

The nightly CM7 -87 file has around 91 MB (here: http://download.cyanogenmod.com/get/cm_encore_full-87.zip), so you should have enough space to copy it onto your sd card. Actually, that leaves more than 15 MB available, so I suggest you also put the gapps in your SD card (here: http://android.d3xt3r01.tk/cyanogen/gapps/gapps-gb-20110307-signed.zip)
About the unallocated space, it will be partitioned by the installer accordingly once you boot the NC with your SD card in it.

Looks like it's working now. I fit the nightly build on there but couldn't fit gapps(144mb). I messed up my froyo install earlier trying to put cm7 on, so I was worried I'd be stuck with a half functional rom for my upcoming 14 hr flight :/
Ok, now for my next question. How do I install it to the emmc? I tried installing it through froyo, but when I deleted the system folder and reset it to factory settings it messed up the froyo install, so now the rom manager doesn't work.
[Edit:] going to try following this thread:
http://fineoils.blogspot.com/2011/04/nookcolor-with-cyanogen-mod-70-emmc.html

What? Gapps is ~5MB only. If you're trying to install with both at the same time verygreen's instructions say that you should flash CM7 and turn on wifi first, prior to flashing gapps.
To install to EMMC you need to burn a CWM SD card, plop the nightly zip on there, boot up with it, then install zip from SD card (select the nightly). Wipe caches/data. Remove CWM card, hit reboot option in CWM menu. You'll need to either have a fresh SD card or reformat the CWM card since CM7 on EMMC requires an SD card in. Instructions for doing this (step by step) are somewhere in General forum by eyeballer.
(Also of note: the info that 16GB cards do not work with this image is no longer true)

Could anybody use a 16Gb sd card so far? I bought one just for the nook and now I found out that its not working - damn! I can't give it back so what? pls help!

I used SanDisk 16Gb and everything worked like a charm.

I did too(both with issues and successfully), the only problem I had with my card is that with the size of cm7 and gapps you ahve to flash them separately, so do cm7 first, put the gapps on the boot partition then reboot into recovery.
if you don't do that you'll run out of space on the boot partition during installation.

I used verygreen's instructions to put CM& on a Sandisk 16 gig class 4. Worked the first time I tried. After CM7 I shut down, put gapps on, then rebooted into recovery.
I think the majority of the problems people are having is NOT READING the part in the verygreen instructions about using Sandisk cards.

Sandisk is not required.. I've also used Transcend and Kingston. Class 4 and 6 between the three.
What is required is a card that's not crap, or works like crap in the Nook Color. An OS does a lot of small operations or uses a lot of small files, so even if the card is great at mass transfers but sucks at smaller ones, it's going to be a bad experience.
Sandisk is one way to avoid it. So if you're buying one, might as well make it Sandisk. Any others.... if it doesn't work right, try a different card. That easy.

[Q] CM10.1 - No external SD card error

Having updated from CM10 to CM10.1 I am getting a repeated error that the SD card has been removed, and to please install another.
My SD card (32gb) is still in place, and through CWM I'm getting "Error mounting /external_sd!"
Any help/thoughts would be appreciated.

i am having the exact same problem with the exact same phone.
if you find a solution, please let me know.
as far as i can tell, although it says it has been removed after waking it up- you can still access media from the card... but from recovery cannot do a backup. pretty odd if you ask me. i download and install each nightly hoping the issue will be corrected.

i was having the same error after replacing the external sd card,
This is how i solve it:
Repartition the external sd; 1gb for the 2nd partition; FAT32 and set both external sd partitions to primary.
Install link2sd app from Playstore; open it and mount the 2nd external sd partition to FAT32. Reboot. Somehow CWM able to mount the 1st partition on the external sd after reboot.

just download an old CM 10.1 and flash with it
it work for me

[Q] Nook HD running CM10.1 on SDcard

I've just read the thread of [Nook HD] CM10/10.1 development (sdcard) updated CM10.1 1/31, looking for help with some question.
My device is Nook HD updated to 2.0.6.
I've followed the instruction in the thread,
- mad a bootable SD with a 32GB SDHC and [sdcard-cwm-hummingbirdv4.zip] (after writing with win32diskimager, the SD becomes the size only few MB).
- saved the file [cm-10.1-20130130-UNOFFICIAL-hummingbird.zip] under the root of the internal sdcard of nook.
- insert bootable SD and reboot.
after rebooted, all functions including settings, wifi and apps are running well.
However, it becomes much slower than its origin OS, sometimes when I point a icon, it takes few seconds to react and continue.
Besides the storage is a bit strange: there are two "internal storage"
- one has 1.88GB for all the apps and Cached data;
- the other one has12.67GB but can't be use at all.
and also a SDcard with 26.5GB (my sdcard was 32GB but after writing bootable image, it becomes totally of only few MB)
Are those every thing normal to the progress now, or it just happened on mine?
Specially wondering that why the internal storage becomes smaller and there is a 26.5GB SDcard? (my nook is 16GB version and ext-SDcard has no more left after writing image file) what is that "no using 12.67GB"?
I am waiting reply of answer and Thank you very much!

The problem is your SD card. You say it is 32GB but you don't say the brand or class. It needs to be SanDisk class 4. If you have a bad brand it will run very slowly.
And your SD should look smaller in the PC after making the card. Most of the storage is in a partition that windows cannot see if the card is inserted into the PC. Your nook should see it though as sdcard. That is what you are seeing as 26.5. And that 12.7 you are seeing is internal media storage and is usable as the emmc folder. The 1.88 is your /data partition and is used to store your installed apps.
So everything is right, you are just using a bad SD card.

I'm using Kingston micro sd c4 32GB, is that why so slow?
And, only 1.88 for apps, will that be easily filled up with those apps which can not be move in to sdcard? Is there any way use the internal storage of 12.7G?

Yes that card is probably the problem.
And 1.88 is a lot for apps, but if you need more, CM10 lets you move apps to SD, which would put them on the 26.5 sdcard.
The other 12.7 can only be used for media.

[Q] How to transfer all data in a hybrid TF card to a new card

Hi everybody:
Now I have installed hybrid CM10.1 on Nook HD in a 8G TF card. Then I would like to replace it with a new 32G card.
My question is how to transfer all the data, use the extra space and does not broke the system.
Thanks

Use win32diskimager to read the 8GB card to a file. The file will be 8GB. Then use win32diskimager to write that file to your new 32GB card. Then use partitioning software like Mini-Tool Partition Wizard to expand the last partition to the full size of the card.
The data on internal memory will remain and be unchanged. You should be able to boot the new SD just like it was the old one. The only difference will be your CM10SDCARD will be much larger.

Just type in a name. Like 8GB.img in the box. You do not have to actually create the file first, win32diskimager will create it. Then after it is done reading that write it back to your new card.

Since that did not seem to work for you, another option is to make a nandroid backup with your old card to internal memory. You might also want to save your files that you have on CM10SDCARD. Then reburn the new card, let it set itself up, flash CM, the converter and gapps to it. Then before you reboot, restore the backup you made earlier. It should then be set up the same when you reboot. Then restore your CM10SDCARD files.

What do you mean it didn't work? Where did it fail? During backup, during new SD creation or restore?
Edit: If somewhere along the line of your trying to fix this, you installed a new image to a card and booted with it before you did a nandroid backup of your old card, you wiped out the internal /data for the old card and it is not retrievable. If you did that, you just have to start over.

I followed your advice exactly. It appeared to work the same way that it did with the working 8GB SDHC card. I still have a nandroid backup of the old card on my PC. It just doesn't work on the two higher capacity SD cards I have. I see that I am going to have to look through the list and find the exact model of a 32 GB card that someone got working. It works fine on the Sandisk 8GB Class 4 card. The two Samsung cards (class 6) of 16 & 32 GB capacity that I own don't work. They are OK for storage use, but trying to install Android on them was a waste of time. I tried so many times. I used your tutorials and others tutorials unsuccessfully. A bum SD card is a bum SD card. I am not exactly a newbie at installing ROMs on devices . I have been doing it on my HTC Desire HD for about a year ever since HTC abandoned us and decided to not give us ICS or Jellybean for our expensive devices. I have Venom DHD on my HTC Desire HD at the moment. I am waiting for my new Samsung Galaxy s4 to arrive this week.
