it was working well until recently, thought it was a problem with intergalactic rom, but noticed a few others having the same issue on other roms, was curious to see if anyone found a fix?
tried another rom and still no luck,
it says that its been ejected and then reads it but says its not formatted, I try to format it but then it gives me an error.
working with a 32gb memory card, don't believe its class 10 but don't have it infront of me right now.

I had this issue in the past and I was unable to recover the sd card even after formatting. Can you see it while in recovery?

did you ever format your sd card to fat32 before? or is it still exfat?
remember touchwiz roms use exfat, while aosp roms use fat32.
Just an fyi although its pia,
Its always best to format sd card via your phone. Save yes files then use your phone to format.
Having said this, if you lose anything try

Give it time... may seem slow but its working.
Works with sd or any hard drive probably phone internsl mem as well.
Gl!
Edit: forgot to mention, try it even if you already formated. Youll be amazed.
Pretty amazing tool for free

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.
I just flashed to CM10M1 and it now tells me that my SD is damaged. I have tried to format it using the phone but the unmounting seems to be taking really long. I have already tried formatting it on my PC, which works, as well as transferring files over, which also works, but when I put it into my phone i comes up with the same error.

I've heard some people had a problem after flashing CM10 with backups done with ROM manager. They said deleting the backups solved it, which doesn't really make sense if you've already formatted the card on your computer, but maybe it'll lead you in the right direction.

Try FAT32. It worked for me. It does say ready to be removed in your storage settings but you should also be able to see the external SD card. Use Solid Explorer and see if you can see the external SD.
Every time I flash anything based on the official JB 4.1.1 release, my 32GB MicroSD card (Patriot brand?) freaks out. The phone will say it's "unexpectedly removed" and then adds it back in, and removes it, over and over.
It's happened on all three JB 4.1.1 ROM's I've tried.
I thought my MicroSD was going bad so I low-level formatted it in Windows (hated doing this) and still had trouble. But ONLY with the card in the phone. Windows usually liked the card just fine.
So what I did to resolve it was use Titanium Backup Pro to "freeze" the "MTP Application". After doing that, my MicroSD works great in the phone and AFAIK, I haven't lost any functionality. So I'm not sure what the "MTP Application" is or does, but so far.... so good.
This post is just a heads up to others, in case anyone else runs into this problem.
Or in case anyone wants to tell me WTF is wrong.
Ive had this issue as well twice. Both times I had to format the sd card in my pc and it will work fine for a while. Im curious to know if you are using es file explorer? Im thinking it might have something to do with this issue.

Ahh hah I duplicated the problem on my phone anyway. I used the my file app to move a rather large file from the internal sd to my external sd and afterwards it lost connection. I had to remove the sd card and install it several times to get it to mount back again. Im not sure if its the moving of the file or the my files app itself that is doing it. I also noticed the media scanner isnt running after moving the file. So I hadnt pinpointed the exact cause but im dang sure getting closer. And I dont think its a bad sd card because I tried another and it did it with it too

Yea it happened with MTP frozen and unfrozen. Ive tried freezing the my files app and every file explorer on my phone. I just cant put my finger on the cause it happens so random. But it seems me and you are the only ones having this issue so im wondering if we didnt get a bad flash when we updated. When I updated via kies it did not do a full wipe update it did what is known as a dirty flash which I never do because you end up with issues like this. So if we continue to ask each other questions we will eventually figure out what the common link as far as if its an app we are using and things like that.
So did you update via kies or odin?
If you updated via odin where did you get your firmware file file from and if you used odin was it odin on the pc or mobile odin?
And was your update a full or a dirty flash?
We are gonna figure this thing out one day lol.....
Edit.... well apparently we are not the only ones having this issue. Over on droid forums there are several s3'owners most on t mobile but anyway it appears there are a few phones out there with this problem and the only fix is to replace the phone and sd card because the phone ruins the card by unmounting it without stopping it first. My phone is still under warranty so I will be calling ATT tomorrow for them to replace my phone and throw a fit for them to replace my micro sd. I paid 48 bucks for this card and I think ATT should replace it since their faulty phone ruined the card

Wow.
I had the problem with two or three different ROM flashes. So it wasn't just one ROM flash.
Each time, freezing MTP Application has resolved the issue for me.
I'm going on ~4 days now with my current ROM and no more issues since freezing MTP.
Maybe there are a couple different SD card related issues out there.
I had the same problem with ADATA and Kingston brand sd cards. I tried the Sandisk 8GB from my old phone and no problems so far.
Freezing the mtp app has seemed to slow it down. The only problem with freezing mtp is that is how the phone mounts to the pc. Mine just did it again but I unfroze mtp to hook my phone to the pc and right after I backed some stuff up and unplugged it, before I could freeze mtp again it unmounted the card. Ive also tried several different sd cards and several different sizes even tried a 2gb Samsung card with the same results. Im thinking hard about going back to ics to see if that will resolve the issue. ...

Try reformatting the 64gb card to a fat 32 file system. 64gb cards come formatted exfat and some s3's have had trouble reading them. Put it in a pc into the card reader and open my computer. Then right click on the drive thats showing your card. Ex drive E or F. Mine is drive N. Once you right click on it click format and a box will pop up and you will see the box that says exfat. Click the drop down box and change it to fat32 then click format and your done. Once it finishes put it in your phone and it should recognize it...

Well my 64gb micro sd came today from Amazon and from what ive read on xda and the net I would need to change the file system from exfat to fat32. So I put it in the pc pull up mini tools partition wizard and it gives me no option to format it, I try windows no option for fat32 only ntfs or exfat so I try a couple of others with the same results. Then I try hp format tool and finally format it to fat32 then put it in my phone and it says its damaged and needs formatting so I do and put it back in the pc and im back to exfat. So it seems to only work in my phone in the exfat format soooo im just gonna leave it alone. Oh I even tried formatting it in command prompt and changing the file format and it fails so now im starting to wonder if thats what happened to my old 32gb card and why I suddenly starting having trouble out of it when I updated to jb is because it was fat32. Maybe this new jb dont handle fat32 well or maybe my s3 dont like fat32. Hell I guess its just a mystery. ....
So I would suggest if your having sd issues try formatting your card to exfat and see if that helps the connection issues

I'm afraid nothing beyond painfully obvious ones - trying with another similar card, trying the card on any other device supporting exfat (if ok, this would provide definitive proof that card is ok), trying on freshly installed latest ROM, trying with the same card formatted in fat32.

It seems like this is the last resort. I will reformat my note 8 and try again. I also forgot to mention, that few weeks ago I was able to transfer one 800 mb file but this stopped happening. So it seems like there is not enough memory to transfer although I tried clearing the memory.

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.

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.

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.

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.

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 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.

I started to reply to you but my laptop crashed. Seems this s4 just doesn't like that 64gb sandisk. I had an 8gb card laying around and that worked like a charm. The sandisk was foramted exfat out of the box. I formated fat32 and didn't work. I wiped it and left it without format. Put in the phone to let it format the card. 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.

I have a SanDisk 64gb micro SD card in my S4, and had it ever since I got the phone about 1.5 years ago. now I am getting the issues you all are getting. I have NOT updated to a new firmware version. and I just backed up and reformatted the card. Very frustrating when all your apps disappear. come to find out they are all being stored on the SD card witch is now not responding... I will try a differect card. I wish they would just leave the phone a lot and stop doing so many updates.. they update one thing it screws up another. Ever since the first update my "Drive" app don't work, and they have no clue why.. not even Samsung knows...
oh well

Just curious as to how you got an S4, 1.5 years ago? :cyclops:
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.

I'm having the same problem. We are not alone, there are numerous threads in the other S4 forums, like this one http://forum.xda-developers.com/showthread.php?t=2281813&page=14
