Hi, so recently my friend gave me his G2 since he just upgraded to the GS3. I wanted to use this for a few months, then buy a new phone myself, but I've run into a problem. I put my 32 GB Transcend class 4 SD card in, and it tells me "Unsupported filesystem, card must be formatted". I didn't want to have to format it, so I took the SD out and put it in my Windows 7 computer, and it tells me I must format it. I didn't want to, but I figured it was my only option, so I tried. The formatting failed, so I tried formatting it with both the G2 and my dumbphone, a Samsung Seek. Neither works. I then tried a 1 GB spare card I had, and same thing happens. It worked just fine with the SD card my friend used in it, so what is wrong with mine? Both cards had worked fine in other devices, specifically an HD2, Droid 1, and Samsung Seek. Can I salvage the cards? Will I be able to use an SD with this phone? Thanks for any guidance.
I'm not expert here, but such behaviour is not standard. If you are using standard ROM without any strange software installed then I would say it's some Hardware failure.
If you have custom recovery, try maybe repartition card in recovery and format in FAT.

It's on the stock ROM from Tmobile, never rooted. I'll try using my sister's phone (rooted w/ custom recovery) to format the card and hopefully save it.
Alright let us know how it goes? Try formatting it in Ubuntu using gparted

I had a similar problem on a warranty replacement G2 I got. I found out that the circuitry of the SD card is built into the case of the SD itself. So, if you damage the outside plastic of the SD card, you have the chance of actually ruining the SD card. The G2 I got had a very finicky SD holder and I wound up scratching/bending/warping/"or something" when trying to insert and lock down the card into the phone. All you could see was a little scratch on the SD card but the manufacturer said the card was toast. I think I went through 2 cards on this phone before I returned it due to the misalignment of the card holder/slot in the G2 itself. Now, I'm a lot more careful about getting everything to align instead of just plopping it in.

When I tried to access an app that was installed on SD, my phone locked up. Upon a reboot I no longer have access to the card, all the apps' shortcuts are broken and all the options like mount SD card, format SD card are greyed out. Also when I connect the use cable there is no option to mount as disk drive anymore. I've rebooted, tried removing the card etc but no luck. Anyone else had this? I can't find my micro SD card adapter right now so I cart try it in my pc.

Try repartitioning your sd card. Could be a corrupt ext partition, or your sd is completely screwed.

I've only had it about 2 months.....get what you pay for I suppose (click). Anyway still no luck with the adapter so I'll see if anyone's got one at work tomorrow.
OK, I found my adapter (and my old microSD card hiding within), windows has no problems seeing the 16gb card and my old (original 4gb) card has the same problem in the phone. For good measure I did a chkdsk on the card.
What are my options?
I've performed a full reset and still got the problem. Anyone got any suggestions?
anyone? I'm thinking it's a desire hardware fault.
any help? cheers
A number of us have had failed SD cards. In my case, Windows could see it well enough to copy most of the data off but failed to reformat it. I suggest you try to copy the data somewhere safe and then reformat in Windows. If the reformat works it's probably a hardware issue. If the reformat doesn't work it's probably the card.
I'm sure others will have different views!
Yeah but it's same with both my cards. I'll give it a go anyway cheers.
The one that came with the phone .. ( 8GB Class 2 ) came up with with a read only error last week ...
The card was dead.
I got a 8GB card class 6... used app brain .. and restored all my apps fine... etc
fab.. phones faster .. no problems
After inserting my old card again I now get the dreaded -
SD card damaged. You may have to reformat it.
Of course when you follow the wizard to format it, it doesn't seem to format it. I did try a full format in Windows earlier, no luck.

Just to help anyone who stumbles over this thread in search of an answer, I've had to send it away for repair, it appears to be a hardware fault. 2-3 weeks.
can a sd card be damaged if its not removed while you gain root or cwm or flash a rom? i have a sandisk 64gb class 10 that use to work fine before i flashed my S3. After i flashed freeSG3 my sdcard wouldn't mount, keeps saying sd unexpectedly removed. it came preformatted as exFAT and worked fine on the stock tw rom. i stuck in my computer and it said it needed formatted so i reformatted as exFAT and copied a couple files to it. soooo.. im assuming it isn't damaged since it works in my computer. still no luck getting it work on my phone though. I tried my other sd's to see if it was the rom maybe but they work just fine, its only this card. im confused to why it isnt working now, but use to work but still works on my computer. ive only had it for a couple weeks and luckly i got it off of amazon so i can still return it. i've tried rebooting my S3, i even tried to mount in it my vibrant after i reformatted even though i know the vibrant doesnt suppport 64 gb.. it said damaged sdcard. ill give it a few more days of research before i send it in for a new one, im hoping i can get it to work again. my other option i was thinking about doing was to restore my phone back to stock to see it would work again. i dont really want to do that but i think i will for the hell of it before i try returning it.
Your SDCard is not damage, as I've mention in your other thread you are probably running a custom kernel that doesn't support exFat.
Either reformat your card as FAT32 or NTFS or flash back to stock kernel that does support exFat.
exFAT is a proprietary Microsoft product. They don't release licensing to open source software like Android. Apparently Samsung as some kind of licensing deal with Microsoft to use exFAT that's why the stock kernel will work with newer SDCARD formatted as exFAT.
I am going to piggy back on this thread and say that I have the "unexpectedly removed" bug
S3 running stock 4.0.4 - it works fine with a 2gb microsd, but I just bought a 32gb micro sdhc class 10 and it just won't read.
Tried exFAT, Fat32 - NTFS doesn't read on the card.
Suggestions?

I was using 32gb card earlier on Stock Rom-unrooted, rooted, RcMix and Xquisit roms without any issue. I know you would have tried but have to ask, did you try copying any data onto the card on a PC? May be some bad sectors are causing it to not recognize.
Can you tell me if CWM or TWRP recognize the card?
I don't have any issues with all my cards - 16gb, 32gb and 64gb ultra sdxc.
I've been putting off rooting it since I was content with the factory rom, but I guess I have no choice. I'll check CWM after I root it.
However, I can't copy any data onto it. Also, the phone recognizes the card but it keeps unmounting/remounting it.
how can I tell if CWM sees the card? Even after root, the phone sees the card, just can't copy anything to it.
Did anyone ever have a fix for the "unexpectedly removed".
Had the problem before. Reformatted sdcard and odin back to stock then flashed cm10 with no problems.
Recently went back to TWFrosty, and the problem exists again. Could it be from going back and forth between TW and Aosp?
My card is fairly new, about 2 mths? Maybe 3.. Weird error, it shows my external sd card blank, then all of the sudden if I leave it be all my files will show back up. Also it has went so far to ask me to reformat the card with my phone. I just avoid the answer, and eventually all my files come back. When I'm near a computer and it does this, I'm able to still see all of the files on the external sdcard on my PC, just not on my phone.
Thanks for all the help..

Sounds like you need to backup then reformat the card. You didn't say what kind/size it is or what format. That can help.

For large (32/64GB) cards, if you're going to use an AOSP ROM, you have to format to FAT32 (or ext3/4). TW based roms will format to exFAT if you format it inside the phone. The drivers for exFAT aren't included in AOSP though.
For some reason my phone says sd card not mounted so i put sd card on another phone and it says the same thing does this mean i lost everything on my sd card or can this be fixed.

Do you have a micro sd card adapter for your computer? (A chip like thing or usb like this that you can put your sd card into so that your computer can read it.) If so, put it into the computer and if it doesn't read it you may have to format it. What all is on there that you want kept? Maybe I can help save a few things, because formatting requires deleting everything.

If you're having issues mounting on multiple devices, you probably have a dead card.
Have you noticed any oddities for your SD storage in the past? (Perhaps missing or corrupt files, or maybe even your phone freezing once in a while when accessing files on the SD card)
As Whiplashh said, try the card using an external USB adapter with your computer. If it doesn't work there either, you probably have a dead card. Even if it does work there, I would highly recommend transferring everything off of it, and recreating the file system. I had a similar problem with my microSD card in the past, and I was only able to resurrect it twice before it completely died...
I am stumped! I got a Sandisk 64gb sd card for this. Naturally, it came formatted as exfat. From stock through 3 different CM based ROMs, I can't get this S4 to read the SD card. I even downloaded a partition manager to format it to Fat32. I also wiped it and let the phone format it. Even after that it would read it. I know CM now supports exFat format. I even flashed separately the script from the original thread. In any case my laptop has no problem with the sd card. Any help appreciated.
I have a Patriot 32 gb class 10 that was working fine until s couple of days ago. Then the phone said sd card unexpectedly removed. Pulled battery and card nothing. Did a format still nothing put that card in my Asus transformer tablet. read just fine took the card thatvi had in my tablet without formatting it put it in my s4 and it read it. this is my 4th galaxy device they should have figured this out by now. Any suggestions.

The sudden unmounting and/or sd card not being recognized by the S4 and other devices as mentioned is a known issue that is usually SD card related. Sometimes it's just a matter of reformatting your card to Fat32 if your ROM cannot read exFAT cards.
But if that's not your issue or you already reformatted your card to the appropriate format, the SD card has failed and warranty/replacement is suggested.
Can happen to SanDisk cards in addition to other manufacturers.
You may hear this issue being associated to SanDisk cards if only because they are probably the most counterfeited card out in the market. But the issue can occur to non counterfeit cards also.
To reduce your chances of having theses issues happen, always get your cards from reputable sources, in blister original packaging, etc. And if the price looks too good to be true, it most likely is. Even if you take the above precautions, you can still have issues.
Always back up your data for that 'Just in case moment' in case stuff happens.
Purchasing a card whose Manufacturer and/or Seller has an excellent return/exchange policy is a plus.
Having a spare SD card available can help you troubleshoot what your issue may be regarding a defective card, formatting issue, device issue, etc.

It did--fat32 and then still wouldn't read it or even mount it.
I sure don't have anything to lose by trying a different program to format that card. It could come in handy even if I don't use it in the phone. A camera comes to mind.
Oh yeah, it was easeUS that I used to format the card in the first place. Try something else.

This happen to me but with my galaxy s3...turned out sd card was corrupted. Good news was Patriot replaced it with a new one....
If the SD card didn't work in other devices I would seek to exchange it. There are other things I can use it in. I just ordered a 32 GB G skill on new egg. That should do it. The other thing I tried on this sandisk is partition it to 2 smaller ones less than 30 GB each formatted to fat32. Finally it recognized one of those partitions. When I get the other card I'll swap them.

I had the same problem as you OP. I've also downloaded programs to change the format type and stuff, but nothing worked, but I fixed it in a weird way.
My 64gb card didn't work on my samsung. I used many programs to format the card to get it to work, but nothing. What fixed it was....
I took that card and placed it inside my old smartphone (LG G2X). Once placed inside, a pop-up promoted me saying my card was damaged and it will try to fix it. I've tried this on my samsung and it didn't fix it, but once I tried it on this old smartphone, the card for fixed and started to work on my samsung.
I don't know if this could help you, but that's how I fixed my problem.

I don't know what your problem is, then. My 64GB Sandisk card works perfectly in my Galaxy 4.
I don't know what me problem is either. When I have the time I going to return to stock and start over. TWRP won't backup onto the SD card either. Wondering if its behaving this way because I rooted the phone before putting SD card in. Though I have done complete wipe (including internal memory) prior to installing current ROM.

Odd SD Card Response
I have recently upgraded from a ATT Samsung Express (Tracfone) moving my 32GB SD Card into the brand new Galaxy S4 I Knoxed up right out of the box just as a matter of principle. I saferooted the phone and installed TWRP which for some reason refuses to load after a few succesful tries and a backup of my system and restore thern reload of TWRP. My concern in this question (unless some knight in shining armour can make sense of my TWRP issue) is that I am not able to write to the samsung branded SD card I removed from the old phone. I cannot create a ROM directory on it when the phone is connected to the PC, nor can I copy files to it. I had hoped to preserve the photos on the card and suppose I can break down and buy an adapter so it will connect to my PC but the point is it "should" work,, no? I cannot create a directory when the phone is connected to the PC nor can I in ES file Explorer. I've also tried to create a directory in root witth ES and am getting the same error. I just want to get the silly balloons off m screen and get google play to run. I am succesfully rooted. I've tried to reload TWRP with Odin only to get the small print int he uper right hand of the screen then no further. I am able to restore my backups thank God.
This is making me batty on a three step process. The card is my main concern right now as I can't load the ROM to it once I get TWRP figured out. Thanks in advance for all the great help I always get. The better I get the more I'll contribute....I promise.

well, a simple solution is to enter recovery and see if the sdcard works there if this way it works, change the rom/perform factory reset, if this doesn't, well, you might try to flash everything again, but i's possible that the sd slot is broken...
i wish you all the luck, let me know
I would copy EVERYTHING off the card to a PC and do a format and try a different file system. I would has perform the format on the phone, to make sure its gets formatted to the correct file systems.
Long story short, It sounds like you memory card is starting to get Corrupted. I have to SanDisk cards that started doing that in the biginning and ended up not being read at all on PC nor the Phone.
Also while its doing that, youll also notice the battery start to drain more, at leasst thats what happended on my Note 3 when I had the san disk cards going corrupt.
Ended up buying new Card and now everything is fine.
I doubt is the card reader built in phone, more then likely its your memory card going corrupt.

I agree most likely the card. I'd download an sd card format tool and do a full format, don't use Windows format then do full check for bad sectors. I had a similar problem and it was the card at fault, but strangely worked ok on the pc.

Thanks for all the advice.
I could read the card in recovery but it failed to format there.
I tried to format in windows but my only options were NTFS or exFAT, no FAT32. But this failed anyway also.
Downloaded a SD format application but this said the card was write protected and to move the lock switch, obviously MicroSD has no switch like standard SD.
So next I deleted all the files on the card and ran h2testw test. This failed and reported card is probably faulty.
Then I checked the contents of the card again and all the original files were back again, so it's definitely 'Donald Ducked'. I was able to get all my files backed up and fortunately I had my photos already thanks to Dropbox & G+.
So I will now look at getting MyMemory to replace it but my fear is they will want me to return the faulty card but it has sensitive information on it that I can't delete. Any ideas on how I can wipe it?

Thanks for all the advice.
I could read the card in recovery but it failed to format there.
I tried to format in windows but my only options were NTFS or exFAT, no FAT32. But this failed anyway also.

How did you attach the card to the pc? Try a usb card reader and then try again. If still problems download mini partition tool (Google) and delete the partition. You can then wipe it properly.
I reformatted the SD card from the settings within the phone and since then it been working fine :\
make sure you're using 2.0USB also..
when i connect my phone to charger
Its been few days i am noticing when i conmect my phone to charger it says 'sd card removed unexpectedly or either it suddenly stops showing content from my phone, then i have to go to settings unmount/mount the sd card frkm storage option and then it shows the content even when charging, or sometjmes it doesn'fshow option for that so on that case i have to restart my phone. What could be the possible reason and solution to that. It was fine on 4.4.4 now i am on 5.0.2 all stock htc one m8 h/k edition with sim unlock and s-off via sunshine.
