Hello I have a t-mobile m919, rooted and have tried several roms. I'm having an sd card issue, it will say microsd card unexpectedly removed at times when playing music from the card. When I format the card from the phone itself, it refuses to mount but if I plug into the computer and format it to fat32, it will mount fine. I started with one of those samsung cards on ebay, used h2wtest and it ended up being corrupt. I then returned that and purchased a sandisk uhs1 card from ebay. Same issue. I then returned that and purchased the same one from radioshack so that I know it wouldn't be a fake. I'm also having the unexpected removal issue. Does anyone else have this issue? Thanks

I'm looking for some thoughts on a problem I encountered. Due to a problem with the camera, I got a refurbished phone under warranty. When I got it, I took the 8GB micro SD (not the original HTC, but a faster card from Transcend) from my old phone where it had worked flawlessly and installed it in my refurbished phone. Wouldn't mount. Put it back in the original phone; wouldn't mount. Computer wouldn't recognize it through multiple adapters/readers. Not erased or formatted, nothing would recognize it. I know crap happens sometimes. I had an old 2GB card that I installed and it worked with no problems.
I RMA'd the card back to Transcend (which is another story) who would not replace it due to a scuff mark on the edge of the card - physical damage!!!
Anyway, I ordered a new Adata card, 8GB class 10 and when it arrived, I transferred files to it on my computer (so it was working) and put it in the phone. Wouldn't mount. Put it back in the computer and no files could be seen. Ran scandisk, files reappeared. Installed back in the phone, wouldn't mount. Now it's fried, too. Computer won't recognize it anymore. Installed 2GB card back in phone and it mounts and works fine.
I've got a replacement phone coming again from TMobile - it's got to be the phone doing this. But I'm out 2 SD cards. I'll try a RMA on the Adata card to see if I can get a replacement, but I may buy another card in the meantime.
Does anybody have any thoughts on this problem? Why would the phone play nicely with the 2GB card but neither of the 8GB cards? I don't think I can do anything different, but at $15 a shot, I'm starting to hesitate buying a new card to put in the replacement phone when it gets here.
Thanks.
As a clarification, the original Transcend card was a class 6 card. The Adata was a class 10 and I read that some phones won't work with some class 10 cards...

as always, the best class to use with phones are class 4. their cheap and they work good
well, i was hesitant bout the whole "which classes will the g2 work with" situation.
i bought a pny 16gb class 10 and it works. so i dunno if its more of a this specific phone situation over an entire group of phones.
Hi guys.
I've been using Qumo microSD card 16gb class 4 with un-rooted Galaxy S2 for a couple of weeks until some day the card just died.
I just deleted a file from card with totalcmd android app and it froze. After i rebooted the phone the card was no longer accessible. I also am not able to mount it in computer.
Thanks to warranty I've exchanged the card to the same one. But after working for just one week the same scenario happened.
I'm now going to try to exchange it for Kingston or Transcend card.
But I wonder maybe there is something wrong with the phone itself or maybe with totalcmd application?
Thanks, Oleg.
I think your microsd card is crappy. This happens with some sd cards. Stick with those standard reputable brands like kingston, sandisk, lexar, transcend and you shouldn't have any problems. Just to be safe, you should perhaps change to another file explored. OI file manager is small in file size and fast.
u shld ave ckd the card , connecting it to pc by a card reader..
Something is fishy with our SD cards (both my wife and I), since they've somehow seemed to "go bad" about 2 weeks apart. We both have the S3 16GB and I bought two 32 GB SanDisk cards for our phones. Everything seemed fine until about 2 weeks ago when her card went out, then last night my card seems to have gone bad too. All the phone says is it's "safe to remove the card", can't access the card in any way. I currently can't find my adapter to test the micro card in my laptop, but I should at some point. Is anyone else experiencing anything like this with their SD cards?
I had a problem with my 64gb Sandisk card that went bad duing a rom flash. I have EASEUS Partition (can be downloaded free) installed on my PC and the partition on the SD card was missing. I reformated the partition using FAT32 and it has been fine now for over two weeks.
Just a note I now remove my SD card when I flash ROMs. I know it should be safe but it takes a few hours to rebuild 58gb.
This phone fried my 16gb card
What class sdhc is it?

My 64gb SanDisk errored too within the first week. Formatted and working since. Mine stopped working when I changed a battery (yes, the phone was off).

where did you buy the card? also what class is it?
I'm having the same problem with my 32gb sandisk class 4. it was working fine on my LTEVO but the moment I put it on in my GS3 the card went dead.
32GB Class 10 PNY formatted to FAT32 has been flawless for me...and I've used the same sd card in two previous devices (E4GT & Evo LTE)

Class 4 SanDisk and I bought them on Amazon. Wasn't a bulk type card without proper packaging either, it arrived in the mail packaged like what you would see in B&M's. In any case, I'm going to need to locate my adapter so I can attempt to format them.

If it is screwed like mine then the adapter will do nothing... my card is completely fried

I find it hard to believe that there is actually a "bad batch" of SD cards from SanDisk... I have a friend that also has an S3 (Verizon) that said his 32 GB card (not sure of the class) went bad as well. It would make more sense that the S3 is somehow making them bad or not recognizing them anymore. However, most of my assumptions may just be wishful thinking.
I had some problems that I think were more CM9/exFAT support related with a 64gb UHS-1 card. I used this to format it and it's been fine since
I've been having a terrible time with getting my Sprint GS3 (stock running JB) to use my new Sandisk Ultra 64GB microSDXC. According to Samsung's site (http://www.samsung.com/global/galaxys3/specifications.html) the phone is supposed to support 64GB cards. The Sprint manual doesn't have anything about types of cards, and the website just echos the same "up to 64GB" verbiage.
So, I tried taking the original format (exFAT), formatting with the phone (exFAT), and formatting with FAT32 (using EaseUS partition manager), and formatting with Win7 (exFAT). In all cases, when I copy the contents of my original 16GB card over to it, I seem to eventially get a corruption problem. It shows up right away when I try to view the photos with Gallery (gallery only shows a few of the 1000 thumbnails, and then closes itself with no error message). With FAT32 I ended up getting the phone giving a corruption alert requiring a reformat (I never got this alert with the exFAT, just gallery crashing).
I tried getting the data (about 13GB) onto the card by copying the contents from my old 16GB card over on a PC (using a SD-card adapter as well as with a microSD reader). I also tried formatting the card directly on the phone and then copying the data over using a microusb cable. I did check the card on a PC with H2test2 ver 1.4 (commonly referenced). This helps to determine "fake" cards. It writes and then verifies data to the entire card. No issues were reported with the full capacity verified. I got the card from Amazon with Amazon as the supplier (no oddball vendor).
Anyone run into this or have ideas? I was hoping to skip over the 32gb point as I like to keep more photos and movies on there for travel.
Thanks!
It is seemingly a problem with the SanDisk Ultra cards, whatever the technical reasons they don't play well with the phone's host controller.
I have had the same issues as you, and so did a very large amount of people. I resorted to buying a Samsung 64GB Pro card and ever I have not had any problems.
I have heard some people talking that SanDisk cards manufactured (Toshiba is actually the manufacturer of the memory) before December were prone to this problem, but this is only what I've heard but you can search on this lead. You can try to replace it with SanDisk service.
Thanks for the reply. I'll try Sandisk support first but keep looking around on here to see if anyone has run into a similar issue.
Anyone else?
I concur with the theory that Sandisk has a rash of bad cards. In my case it was a 32GB card just konk out in less than a month.
Their customer service was excellent in replacing it though. Good C.S they have but I'll avoid their cards for now.
I keep getting a usb storage damaged message. I have read that it is sometime an issue with the galaxy s3. Also sometimes when I first unlock the phone it says prepping sd card even though I did not remove it.
Also my SD card is a SanDisk 64gb class 10. I have read that this can be an issue with a certain crop of SanDisk.
Any tips? As of right now entitling works and if it's just messages popping up.

Have you tried using the SD card in other devices and on a computer?
I had a *similar* problem with an old MicroSD card in my original Galaxy phone and formatting the card seemed to work. I can't speak too much to your issue because the largest MicroSD card I've used is 32 and it's been flawless.
Yeah, verify across devices first. If not, try filing a claim with SanDisk if you purchased the sdcard only recently and it's already gone bye-bye.
