Is it a Class 10 or UHS-I device? If so, the standard Nook kernel appears to have a bug. If you reboot your Nook once or twice, it'll probably recognise the card again.
If that isn't it, you'll probably need to get it to a PC to chkdsk/fsck it. If that isn't it, you might need to get a slower card for your Nook.

unfortenutly , my pc isnt working now .......the card work for me for a year ...... just yesterday whebn i open my nook tell me unrecognize sd card :/
and it have a full of important books

Does your Nook offer to format the SD card? Don't let it.
If all the files appear to some device, then don't format it!.
Step one is probably to get your PC working 100%.
Can you copy all the files off your phone to the PC using USB Mass Storage?
What speed class is your SD card?
Does dmesg in ADB show a lot of -110 errors?
See: http://forum.xda-developers.com/showthread.php?t=2297800
Recently, I corrupted my Class 10 card.
I switched over to a clean Class 4 card.
In 10 minutes, using adbsync, a makefile and various original directories on my PC I had restored operation to as it was.
Make backups.

u r right renate , i know that all i need working pc and just move all files and format my sd card then move fikes back to nook, or as the other post hear say just do chkdsk via windows consol and will fix sd problem , so ...... i was asked if there way to repair that by nook device it self???!
any way i will try fix my pc as soon as i can ....also how i know my sd class type and what the defferance between this classes ?!!
thx anyway

On our Nook there are two utilities for checking/fixing filesystems: e2fsck and fsck_msdos
The problem is, do you want a system that is having low-level problems with a file system to try to fix that file system?
(The answer is no.)

[Q] Is it possible?

Hey. I have owned my Wildfire for a week now so I am still a noob. I wanted to know if it's possible to install a custom ROM on the wildfire without an SD card so basically do it through USB. I have seen some phones can do it with Amon RA recovery but I don't think it is possible for the Wildfire.
Thanks.
Dont think it is although why would you want to do it without? The wf comes with a sd card
Sent from my GT-P1000 using XDA App
Because when i put my SD card in the adapter and put it into my laptop it cant open the card and asks "do you want to format" and when i choose yes it says "unable to complete format" so im screwed with that SD card
Use paragon partition n look on YouTube 4 a video that will sort it out n will fix that error
Sent from my HTC Wildfire using XDA App
Still dont work its not even showing up on my computer now ive probably ****ed it somehow but on my phone it says 1.83gb free space. weird.
Dose paragon partitioning show ur sd at all if not erm check to make sure ur SD card reader is ok bu using a different SD card
if paragon partitioning is showing ur sd card.
is ur SD card signed as active and does it have a volume letter as these thing will stop I from formating the SD card
Sent from my HTC Wildfire using XDA App
It showed my SD card then when I tried to format it would only show my hard drive and plus the free version does not let you do anything to the card.
Try Panasonic SD Formatter:
http://panasonic.jp/support/global/cs/sd/download/index.html
E: Probably unrelated, but, make sure your card reader supports SDHC cards.
1.What happens when you connect the phone via USB and choose mount as disk drive?
2.When you use the SD card adapter, and right click on the SD card's drive letter if there's an option to "open as portable device" try that also try updating your laptops card reader drivers.
3.Use bluetooth to transfer the ROMS?
4. If you're already rooted, try formatting SD card via ROM MAnager.
As far as I know you cannot install custom firmware (a "ROM") without an SD card.
You don't have to use your SD card directly from the computer to install custom firmware. You can use file storage mode on your phone's USB connection or adb to access your SD card through your phone on your computer.
To install CyanogenMod with the help of adb, follow the steps in hxxp://wiki.cyanogenmod.com/index.php?title=HTC_Wildfire:_Full_Update_Guide and put the update.zip into the root of your SD card with this command:
Code:
adb push update-cm-6.1.0-buzz-signed.zip /sdcard/
You need to have your phone connected to your computer, have the appropriate drivers installed to do this and have USB debugging enabled on your phone. Documentation on adb is available at hxxp://developer.android.com/guide/developing/tools/adb.html
An alternative way to the above adb method is to enable USB phone storage mode when you connect your phone to your computer and transfer the update.zip file to your SD card.
Hi guys thanks for all your help I have fixed my problem. All I did was use a windows 7 laptop and it worked.

【Urgent】SD card become read only under android

Urgent!!!
I don't know if this is a bug or not. I used to copy files by selecting the disk drive mode. After that I will safely remove the device under windows before disconnecting the usb cable.
The problem is sometimes after copying files to sdcard, the SD card will become read only under android. For example I cannot copy or create files using file explorer. When using camera app it says "Unable to save file to SD card due to insufficient file permissions". When using album it says "SD card unmounted or not present".
After the problem occurs I cannot access the SD card via disk drive mode anymore, unless I physically removed and reinsert back the SD card.
The strange thing is I can still access the SD card in PC via card reader with no problem. I can also view the existing files in the SD card under android (eg opening .apk in SD card)
I tried flashing the ROM for 2 times and with a different SD card. Also I formatted the SD using Panasonic SD formatter and partitioned properly. The problem still appear after several access under disk drive mode. Million thanks!!!
I've noticed the same thing in the DL DesireZ v3.3 nand ROM...
But now since I've switched to skink_Clean_Desire_v1.0 I don't have the problem any more...
No problem solver I know... but just to confirm the issue!
It was also read-only when I had disk drive mode chosen and connected to my win xp pc!
so when I deleted files over the computer they still existed...
I always remove the sd card securely!...
hope this helps a little bit!
Memory cards get weak after awhile...Had d same issue with a Memory card...it works well on WinMo but messes up just as u described in android after a format n a few read & writes...Froyo has also been reported to ruin memory cards...Summary, there's no real solution as i've googled all over....My advice is for you 2 get a new memory card, capacity & class (d higher d number, d better its read & write speed) is up to you...I'm using a class (4) 8GB card n its been alright.
P.S. Stop transferring files via d disk drive option in android..stick to using memory card readers or d MAGDLR function (though some also report file errors with dis).

Thanks for your reply
But how come windows and wm can read and write normally but it doesn't work in android?
Also, I have been using NAND and its disk drive option to transfer file in Cotulla's desire stock Rom and there is no problem at all. Would the problem be related to app2sd since the card has a ext4 partition?
do a chkdsk on your micro-sd card. let it repair and then don't delete the LOST folder in your sd card. ^^ you will be able to mount as read/write after this

Try a chkdsk as well...But in my experience, i did it several times & it only acted as a band-aid...As it reverts to read only ltr on...

So is this a SD card problem or ROM problem?
Previously I had been using Cotulla Desire stock Rom for a month and the problem didn't exist.
I don't mind buying a new SD card if it can completely solve the problem. Thanks

[Q] SD card problem

I have a MyTouch 4G rooted, with Ice Glacier 1.1.6 and I was trying to remove some files from my SD card and when i eject my phone, all the files i deleted appeared back onto the sd card. I tried everything to fix this problem. When i tried to format the card using a card reader, i get an error saying format wasnt able to be complete. i tried error checking as well. i am not able to add files to the sd card too. does anybody know what is going on??
thanks!
Try formatting it thru the phone.
Settings -> Storage -> Format SD Cards
just tried that, did not work. after i click format, the sd card would get mounted again and everything is still on the sd card..
this is what i have noticed, i can delete files using astro and it will stay off until i unmount it and mount it again. thats when the files appear back on the sd card.
Hmm... can you open the files on your PC?
yeah i can open files on my PC. this is weird. when i take pics, itll save onto the sd card but will be gone when i unmount or connect my phone to the computer so i can see the files on the sd card
I've heard of this once before. Solution was to put the sd card into an adapter and format with a camera.
format with a camera? meaning to plug this sd card in a digital camera and plug the camera into the pc then format?
No, format through the cameras menu options.
whenever i tried to turn on my camera with this messed up sd card in there, the camera doesnt even want to boot up....any other suggestions??
Sorry, thats all I got.
Sounds like a bad disk. Run a CHKDSK /f from your pc.
Sent from my HTC Glacier
chkdsk didnt work. at the end of the process, it says "disk error occurred during the writing of the file allocation" ??
It appears you need to go shopping. However, the SD card should be replaceable under warranty, unless our warranties specifically exclude the card. Call your local T-Mobile dealer and see if they'll replace it.
Yeah I think its time for a larger memory card anyway. So all I have to do is copy everything from my old memory card onto the new one that I will get then stick it in my phone right?

[Q] Sd issues. a500 not recognizing sd card

Hi all. I have a stock a500 with 3.1. Not rooted. I put in the 16gb SD card with files in it and I don't get any indication of the card in the bottom right corner. My phone however will recognize it and the files that are on it. Any suggestions? Ty for any replies
"Try unplugging it, and plugging it in again" - Mistabishi 'Printer Jam'.
What FS is the card formatted to? Have you tried any other card that is known to work? Also, try formatting the SD as FAT32 again from the phone.
I am having the SAME issue on my acer. It wont recognize my 16gb sandisk card. I tried formatting as described and I tried another card. Both are showing up in my HTC inspire but nothing on the acer. Whats the deal? When I go to storage in settings- the external SD total space is recognized but it is not allowing me to access it for storage using app2sd?
this SD card worked just fine on the transformer I took it out of.

Are you even able to see the SD card? check /mnt/sd-external to see if it shows up. If it's there, create a directory, then delete it. Also, check the ".android-secure" hidden directory that should be on the SD card after using app2sd. If the permissions are not set correctly, you won't be able to use app2sd with it (reason for create/delete of the directory). Sidenote, I've seen quite a few apps named app2sd, some of them listed are showing up on my end as non-working with the A500 where others listed should work fine.

Still, that does not give me anything to go on. Did you format the card again? Is the card formatted in FAT32? Have you tried formatting the card from your computer using a card reader? I've had SD cards not show up before, reformatting them correctly solved the issue each time. If you don't know what filesystem the card is formatted with, grab a LiveCD with gparted on it (almost any gnome distribution) and I can help you from there. I haven't used Windows since XP SP2 was first released (FCKGW-... if you know what I mean) and I have refused to touch anything Apple since the IIe. Hence the signature.
formatting
Not sure what format they are in. I used a thunderbolt to for mate and a fsscinate and neither were visible. I'll go check what you recommended above though.
What are you guys talking about?
To the OP: You won't have any indication at the bottom. That feature doesn't exist on our devices (but some custom roms based on xoom and ?ASUS? have it). Just check the System screen to see if it finds your sd or simply make a photo from your camera (just set it to save the pictures to your SD). Or use a program and check /mnt/external-sd
To da9b16: a2sd won't work on this device (besides it has enough internal memory).
You'll only be able to access SD directly from your internal memory if you root the device and use a program that creates a symlink from /mnt/external-sd to /sdcard (USB Mount All does this but it's not free) or if you simply navigate to /mnt/external-sd with a file explorer.
I hope that this clears some confusion.

hey i have a similar problem , when i put my SD card does recognize but the apps like photo gallery or play music wont read any file from my SD card what can i do

CWM wont show SD card contents...

So I rooted this stupid tablet and put the custom acer recovery app or whatever it is on it. Installed the proper CWM, and when I boot into recovery and try into install zip from SD card all it shows is "Lost.dir". Nothing else. What am I doing wrong?? The ROM/Kernel I want are on the root of my sd card, why isn't it showing up?
Because the tablet isn't stupid it knows exactly where the files should go but you didn't put them there? You just put your files into a wrong directory namely your internal storage.
/sdcard/ = internal storage which isn't used by CWM
/mnt/external_sd/ = SD card which is accessed by CWM
EDIT:
And in case you're looking for USB... The tablet mounts it under /mnt/usb_storage

Some SD cards can not be seen bybrecovery.try formatting your card on another android device or a format utility from your PC.use fat file system.if still no luck try a fifteenth SD card

Take your time and have patience. I know the feeling. How are you transferring the data to the micro SD card? Can you use a file manager app to access the card, /mnt/external_sd?
Sent from my HoneyVillain 1.1 HC3.2 using Tapatalk
Again over and over ..try another SD card maybe two this is a very common issue.very common
Try diffrent SD cards if you have not
Or use a USB drive and flash from there. I do it all the time if I'm to lazy to copy the files to my SD card.
I am also stumped with the the acer reading the micro sd card. I am able to see it using root explorer. However, I cant see it when it is connected to my computer. I had to place my sd card in my galaxy tab in order to transfer files to it, and then place it in the iconia. That appeared to be the only way to put the rom on the root of my sd card. I want to save my stock back up to my computer in case I damage my sd card, but there seems to be no way to do it with out removing the card and placing it in another device. Am I missing something? Dont want to start another thread, so I'm asking here because it looks like it's been seen by other users.

FYI ( just in case ) !!!
When fully booted... SD CARD is the internal storage... and the physical card is shown as EXTERNAL SD CARD !
When at CWM recovery... SD CARD is the real physical card !
