Hi there.
I have a 4GB sd card for my SGS SC-02b. Whenever i insert it into the phone the message at the notification area appears saying "sd blank or has unsupported file system". I tried formatting it and tried to mount it but its not working, i m not getting any error message while mounting or formatting, its just not working. I tried reinserting the sd card but still the same.
Looking for some kind suggestions

Is your sdcard locked by that little plastic knob on your card?
what files system are you formatting with recommend you use this app to format externally in your computer with a card reader

thanks for the tip, its working great now
Well, its not working again. It was working for a while, then i had to root my SGS so i removed SD card, rooted my SGS and then reinserted Sd card, now its saying Damaged SD card you have to format it, when i format it, no error message appears and nothing happens and notification area is still saying Damaged SD card.
Any suggestions??
What brand is it, dont tell me its a unbranded one, or a cheap ebay one, it could be a fake one, use you pc to format it fat or use the sd formatter, when you put it into the phone, unmount it then format again using the phone before use.
I have a 32gb adata class 2, 32gb lexar class 10, and many 8gb and 16gb from kingston, toshiba and sandisk in class 2 to class 6, all works.
Connect phone with USB cable in mass storage mode .
Format the SD card then run scandisk/error checking on the card .

I am writing this n00b friendly howto for anybody who will encounter similar problem that I had, since I couldn't find much info how to solve it on this forum.
Recently I have flashed CM9 and later CM10 preview on my Galaxy S3 I9300 with 64 GB Sandisk SDXC card. The card was formatted in Samsung stock ROM, so naturally, it was formatted as exFAT. CM9 and CM10 reported it as "damaged SD card", but this was expected, since open source AOSP ROMs do not support exFAT. However, when restored to original stock ROM via CWM recovery, the stock ROM was showing "damaged SD card" error, too! Not sure why this has happened - the only info I found was someone mentioning that "CM9 is known to do this on exFAT cards" on this forum.
Connecting the card (via adapter and card reader) to computer didn't help - it showed as a RAW partition, Windows was asking to format it and even reported incorrect size. Trying about 7 different open source and commercial recovery tools did not help. However, if booted to recovery mode, CWM could see the card just perfectly!
So this is how to get the data back:
1. Boot to CWM recovery mode (power off the phone, then hold Volume Up-Home-Power buttons for 5 sec)
2. When in CWM recovery mode, connect phone via USB to computer. The phone should be recognized and drivers installed (if not already).
Note: I had problems with Windows recognizing the phone in recovery mode on some PCs (only 1 out of 3 worked, actually). To solve this, installed drivers from Samsung Galaxy S3 Toolkit (first step after toolkit installation) and problem gone: http://forum.xda-developers.com/showthread.php?t=1703488
3. Run adb command (from Android SDK platform tools) to ensure that the phone is visible to operating system - it should show serial number of the device and "recovery" next to it:
adb.exe devices
4. Browse the phone to find the location of sdcard (mine was /sdcard):
adb.exe shell
Note: when first time connected to phone via "adb.exe shell", running "ls" in /sdcard directory came out empty. Had to "exit" from shell and do "adb.exe shell" again.
5. Pull the files from your device using "adb.exe pull" command:
adb.exe pull /sdcard c:\temp
replace /sdcard with your sdcard directory on the phone (if different) and c:\temp with other folder on your PC, if you wish.
That's it! After files are copied, reboot to stock ROM and reformat the card. You can now copy all data back to it from your PC!
Now I'm trying to find a way to format the card to FAT32. Seems not so straightforward with 64GB cards!
Sincerely,
satanxda
Man! pity I didn't read this before I formatted my "damaged" card ... good to know there's solution for future

I had the same problem. From stock went to CM10, exFat got corrupted and then went back to Stock still external storage card showed as damaged.
I took the SD card out and put in adapter and then connected to PC. Then from command prompt ran chkdsk <Drive_Letter:> /f and it fixed the errors without me copying the files to PC.
Hope this helps.
And to format 64GB sd card from exFAT to FAT32, use guiformat tool or EaseUS partition master. I have formatted my card to FAT32 using EaseUS partition master.

With this problem you can restore data in more easily way.
Insert your SDcard in CardReader, connect to PC, run Command line (cmd) and type:
chkdsk X: /f ,
where X is your card volume name. After operations is complete, you can use you card again and NO data had been lost.
Sorry for my bad english.

Tried it before posting this howto, but EaseUS didn't see the card at all. Windows disk manager in the meantime reported incorrect size (27 GB for a 64 GB card) and when formatted with guiformat I got a 27 GB partition. Could be a problem with card reader - will try another one as soon as I get my hands on one ;]
mahendra1020, magicm3n: in my case using chkdsk was not possible, since Windows showed the SD card as a disk with not formatted RAW partition (suggested to format it). To run chkdsk, partition type must be recognized.
And by the way, thanks everyone for comments and suggestions!

Yeah even in my case windows showed sd card as not formatted but chkdsk still works.
Try /f instead of /r as arguments for chkdsk.
Are u formatting as fat or fat32? For me both the tool worked.

Probably you are right. Checkdisk button was disabled for me when right-clicking->Properties on the drive, but anyway Windows was reporting wrong size of the card, so I didn't want to risk forcing repairing and didn't invest too much time to that. But as I said, maybe it's the problem of my quite old SD card reader
By the way, successfully formatted from exFAT to FAT32 by using this Android tweak to mount the SD card as USB Mass Storage device on PC (so basically turning the phone itself into a card reader) and formatting in Windows with guiformat:

And did you get CM10 to read all of the 64 gigabytes?
For me CM cannot read the SD card over 32 gb.
Formatted my 64gb SDCard using EASEUS Partition Master to FAT32.
CM9 recognizes all the 59GB+, reads and writes on the card just fine. Didn't install CM10 yet, so don't know if that will work...
FWIW; the Chkdsk /f command did fix mine, and just as well, cause nothing I did (on multiple machines) could get the darn thing to mount in CWM.
yep, chkdsk does fix my 16g exFat card, and it works back just fine now. and before, i tried the CWM way twice, nothing i could pull up, os hints "remote object '/sdcard' not a file or directory"
I've had the same issue, and am really struggling to get anywhere at all with it...
I tried the method in the first post, but running ls on /extSdCard just gives an empty directory...
When I mount it in a reader in windows, it reports zero size and a 'please insert disc into Removable Disc (E: )' when I try and open it...
Even when I just threw my hands up and said 'ok phone, format it' it just says 'unmounting SD card' and then just backs into the normal screen.
At my wits end with this, I suspect the card might be fried, but want to get in if possible as it has my only stock backup!
Running the most recent CM9

What about /storage/extSdCard/ ?

hmm, well storage isn't part of the structure when is run ls after using 'adb.exe shell'
tried it anyway, get 'can't cd to /storage/extSdCard'
interestingly, when I try and get into just the 'sdcard', which I guess is just the internal storage?
I run 'cd sdcard' and the folder that I get into is /data/media
this is confusing, anybody any ideas?

Please add this simple info to the OP!
P.S.
Windows 7 said the volume is in use and if I wanted to dismount it before it would allow to continue checking/fixing it. But at the end it worked perfectly!
Thank you very much! I had so much stuff on this card that I haven't backed up yet..phew
Thank you for this guide. Help me get all my data of my "Damaged" 64GB sdxc card
I have the same issue. Flashed CM10 M2 on my tmobile S3, got the error that SD card is damaged, restored stock image from backup, and I'm still getting the bad SD card error. I'm using CWM 6.0.1.2 and mounting the external SD failed. I don't see the contents when I connect through ADB. Mounting sdcard from CWM mounts /sdcard but that is the internal storage which is not what I want. I also tried connecting the card to my laptop running XP using a micro-SD card reader and running chkdsk but that reported the disk as a RAW partition. Any ideas on what else I can do to copy files off of the card?
The method mentioned in OP worked for me, using a macbook air with mountain lion and android sdk for adb installed.
After mounting the external sdcard in cwm and copying the files via adb I partitioned the sdcard (sandisk 64gb sdhx) with the inbuild harddiskmanager in mountain lion. You have to choose FAT (MS-DOS), it will choose fat32 automatically. After partitioning and formating the sdcard the card is recognized under cm10 and samsung firmwares.
OSX has no 32gb limit on fat32.
Hello,
i have a huge problem with my sd card. Currently i have Dorimanxs latest GB (lite version) installed and the rom itself
works how it should, but if i reboot the SD Card gets damaged, a lot of apps are missing and there are a lot of files with crazy names.
I tried to format the Sd card and i think it will be the same next time.
Any idea?
cheers.
Had similiar issue. Test your card by putting in sd card reader connected with pc and run chkdsk command in command prompt in windows.
If doesn't help, download aplication for win called sd formatter and make full format of sd card.
Your problem could be related with some kind of app2sd script IF its in use with your rom or which was also my case your sd card is at end of life span.

I doesnt have a sd card reader but i formated my sd with a HTC One V from my Sister and it worked. thx for answer.
Like alot of you, I recently had alot of trouble with my sandisk 64gb micro sd card. this fix is pretty easy but it worked for me! so check it out:
you need two programs: SD formatter( can be found on the sandisk website) and easeus partiton master( you can use any program that lets you format partitions)
you will also need the sd card adapter to put you micro in, and an sd card reader
Step 1: connect your sandisk 64gb microsd card to the computer with the adapter it came with in the box. My laptop has the sd card reader built in
I dont think it will work unless you connect it this way.
Step 2: open sd formatter, it should have recognized your card if not click refresh. after its recognized click Options and set format type to full (overwrite) format the sd card. this will take a long while so you might wanna go watch tv or something?
step 3 : after its done formatting open partition master and right click on the sd card and format it to fat32. your going to have to click apply on the top right hand corner for it to work
you should be set. DONT FORMAT IN THE ANDRIOD SETTINGS. for some reason when ever i fixed the micro and tried formatting it in my phone it would mess up everything thing again.
I keep a 32 gb in my s4 now and use my 64 in my note 10.1 because i need the space there more. Let me know if this works for you!

It really depends on the troubles you have, most of them are some kind of incompatibility with the S4 firmware and the 64GB SD card and formating this will not help. My issue was each time i'd put music on my SD, my system status would trip to custom, also my music would not always show up at boot. This has been a recurring problem with the sandisk cards no matter how i formated it. And yes, i did use SDFormater 4.0 and still had the issue. My only solution was to get a Samsung 64GB SD and no issues since
Sometimes mine removes itself, but a media rescan or reboot fixes it. Doesn't really bother me.
I use a 64gb PNY class10 and its flawless for me.I think the issue is witg the sandisk bran.

Figured this is a good thread to post my experience.
I had a MicroSD card I thought was bad. What happened was I was formatting the device to ext4 at the time using a older microSD USB adapter i had. Basically, the microSD card reader died while it was in that process. Using a microSD > SDAdater and a built in SD card slot on my laptop I was unable to format the drive in Windows or MacOS. (I was formatting the device via the USB reader on my Desktop in Ubuntu). Ubuntu does not see my card reader on my laptop so I was unable to use that). I thought I killed it. It was a SanDisk microSDXC 64gb card.
So I ordered a new Samsung microSDXC and a new microSDXC USB card reader. I got them both. New card worked great. I decided to play with the card a bit. Using Ubuntu, gparted specifically, with the new adapter I could no create or modify partitions on the old microSD card. It would fail out every time, different errors for ext4, exFAT and Fat32. So. In Gparted I went to Device > Write new partition table.After I did that I would able to format the drive in Ubuntu to whatever filesystem I wanted, and the card works in the phone, mac, windows, everything.
Just a heads up to help any others with issues. Rewriting the partition table may help if somehow it gets corrupt because of some write fail,
I ve 2 64gb sandisk 10x microsd with Samsung S4 I9005 with Android 4.3. I formatted with android, also Windows 7 64bit with various types of sizes on laptop. However on laptop or on phone after writing some files and disk scanning, it gives many disk errors. I wonder if it is software or microsd hardware problems. There is no problem with 32 gb.

Found the Culprit!
Considering I encountered this write protect error TWICE with the exact same product, and after having read forums that show it's a common problem, I conclude that the problem is with either this specific SanDisk product or a particular batch of this product:
Exact product specs: SanDisk Ultra 64 GB MicroSDXC Class 10 UHS-1 Memory Card with Adapter (SDSDQU-064G-AFFP-A)
These carry a lifetime warranty. A word of advice: if you go for a replacement, ask for a different 64GB model, or try a different size of the same model (I got 2 x 32GB cards instead). If they insist on giving back the exact same model, I'd suggest you use that card anywhere except a smartphone!
Dear Members,
i am using Samsung Galaxy S-4 i9500 (rooted device) and facing an issue regarding SD card. my SD card not accessible, the msg i saw on my phone is "Sd card is blank or unsupported filesys.." Now its doesn't format or showing any dat. i need your help guys.
Thanks
Hey, I have the same problem too. I tried inserting into my PC but it also didn't recognize it. I also tried opening the command prompt (cmd) and running this command chkdsk /X /F E: but no luck. So I ended up buying a new one.
You may want to play around with the partitions in the SD card on the PC.
