Hello everyone. I have been having issue after issue with this 64GB MicroSD I got recently. I bought it at a local Best Buy the other day (there was a sale going on; $49). It is a SanDisk 64GB Class 10 MicroSD. I got home and formatted the card. I formatted it in FAT32 with the HP USB Format Tool that I always use for SD cards. Well, the moment I put it in, it said that it was damaged (occasionally said that it was blank). I tried removing it and reinserting it, and the same thing. I have tried putting it in a different GSIII as well as a Droid Razr, and same. I tried reformatting with the same tool, but this time doing a long format. Same problem. I also tried EaseUS Partition Master. Same problem. I have also tried using a live build of Parted-Magic. Same problem.
I am starting to think that the card is a dud, except for two things:
1: It works fine in my PC. It reads the exact amount free, it shows all of my files, and it let's me play them with no issue.
2: It shows up in Clockworkmod just fine. I can back up to it and flash from it with no problem.
I am really just left here scratching my head as to what the problem could be. I made sure that all of the settings are correct each time I formatted it. I have tried switching ROMs and still get the same problem. I have tried just about everything that I can possibly think of to get this card working. I am hoping that someone can help me with my problem.
You can call them and they will send you a new one, I did it about a month ago.
I was having similar problems.

Do you think it is a problem with the card? If so, I am still within my return limit at Best Buy. I can just take it there instead of waiting on a replacement. Just wasn't sure if it was the card or something I was doing.
It's a problem with the card. I had the same problem with a 32Gb card from Sandisk. Files could be seen for a day and then disappear! I could tell the camera app to save to the card and that would also work for a while only. Fo/ders create on the card via the computer would do the same. In one situation I created a folder on the PC, copied a film to it, viewed the film in my phone add took some still from the film. The next day the film and folder was gone put the still -stored on the internal memery- were still there.
Contact sandisk. They must be aware of the issue.

OK. I went to Best Buy and exchanged it the other day (lucky I bought it when I did; they marked it up to $99!). I am still having the same problem. I am not sure what I am doing right. I have been formatting and copying the files while it isn't in my phone. I am using my card reader in my desktop. Could this be the problem? Am I able to format it while it is in the phone without using the phone's format tool?
First you use the tool to format the card to fat32. Once you do that you are to install it to your phone then use the phone to reformat the card again so the phone can use it. Card will have issues with phones when you format it with the tool. Your suppose to format it with the phone as well after for it to properly work. Good luck

Just thought I should post on here and let you all know what my problem was. I got it all sorted out and Play Music is showing all of my music. My problem was that EaseUS defaulted the partition as a "logical" partition. This was leaving about 75MB unformatted, and Android didn't know how to handle that empty space. After changing that to a "primary" partition, I have not had any problems. Serious derp on my part. Lol

I found that if you format the card from in the phone and then transfer data, you shouldn't have any issue.

There is no lock on it, its a microSD...
Funny thing is I tried every possible way to Format it and all show "format complete" then when I remove the card and plug it back it shows the old content again...
Well its a common issue apparently, contacted Sandisk and had my MicroSD RMAed. Now the thing is I don't want this to happen again, who might know why my Android locked my MicroSD? Is it the custom ROM, is it an app that grants read write access like Titanium backup? What could it be?
I've never had it happen to my San's lol try putting it in an SD adapter already in a locked position then put in unlocked position and place in computer

Try going to the micro sd folder on your computer and highlight all the folders and delete if you havent tried
I tried everything, had it RMAed now got a new microSD from Sandisk...cost me shipping so hope this doesn't happen again...
Did you try a low level format

Every possible formatting way was tried. CMD, special software, through windows (quick and full), through the cell phone, directly through a microDS reader, different microSD readers, different computers.
Like I said I tried everything!

sounds like u didn't low level format, to be honest. I less u specifically used a low level format tool or did this command from Linux:
dd if=/dev/zero of=/dev/sda1 bs=1m
u didn't try everything my friend. none the less doesn't matter, glad u got a new one on the way
i have the same problem i format on my galaxy note plug in to my pc i format it change it to ntfs and once is finished 100% formated i un plug it out y plug it in and everything comes back like if it didnt happend what i did help
You have to RMA it there is no other way, it is locked for good. I spoke with SanDisk and that's what they told me. It happens allot with the 32GB microSDs when used in cell phones.
the same thing happened to me with my sandisk 32 gb class 4 card.
it wouldn't format or write any files to the card
but it would still read the files and copy them off the card without any problem
It was a very odd issue. Considering the card has a 5 year warranty i contacted sandisk and they said it was defective and they gave me a prepaid label to send it to them.
i told them it had personal info on the card so they said to snap it in half or drill a hole in it which i did. So I sent it in then the day after they got it they sent me a replacement. Why did you have to pay shipping? Everything was free for me.
im having an issue all of a sudden where the external sd card wont delete anything i tell it too. i mount it to the computer and delete things that way and copy things on but when i disconnect everything is like it was nothing happened.
also formatting it in setting via storage did nothing all the files are left in perfect order
Ive even mounted to the computer, formatted in MY COMPUTER and it says its completely empty. Then i unmount it and guess what nothing was touched. can someone please help
I take that back even deleting within my files does nothing.
I just stuck in my sandisk 16gb class 4 and it isnt having any issues so it must be the 32 gb sandisk class 4 is the card messed up?
I'm using it with a skyrocket and im on skyics with the latest base. I'm posting here because this card has been in many other phones and never had an issue till now
pwnerman-
Reading your description of the issue .. have you tried physically removing it from the phone and inserting (either by adapter or multimedia slot as most computers have now-a-days) directly to your computer ?
Meaning .. have you tried doing this without it being in the phone ?
Yes .. I snapped at you in the thread and I apologize .. with all the BS going on in there, more and more people are getting on edge.
My answer in the thread also stands in regards to how the card is formatted. I honestly do not know your experience with computers .. thats why I threw it in there.
I have a Sandisk 64GB card in my Skyrocket running Seans latest ROM .. only way I could format my card FAT32 was actually using a single command line program called "fat32format.exe" .. and with ALL of Seans ROM's, I have never had any issues with SDCards at all.
Here is my original thread about the Sandisk 64GB http://forum.xda-developers.com/showthread.php?t=1586295
I've done everything but attaching it directly to the computer because I have no adapter to do so. I bought one of the cheap dollar ones on Amazon a few hours ago. I've used that card in like 10 phones on triple as many roms and never had a issue till now. I do think it could be a Rom issue because the other Guy was having issues and this was the first time I did anything on the card since switching to the 4.0 skyics Rom.
I even put it in my captivate and it wouldn't even format in recovery mode. So I honestly don't know considering it wont work in the captivate either

I've had a 32 gig micro SD in my phone for a while now. I recently took my Siii out of my pocket only to find that it says the SD is unmounted. Odd, but not unheard of in the world of custom roms (paranoidkangdroid 2.something, rather recent though, 4.2.2 JB) So i do the sensible thing: Run into the storage menu, and lo and behold, its not registering. I pop it out and in, not registering. I reboot, and the damn thing still isn't registering. Then I take an old 2 GB micro SD and try it. This one worked just fine. 32 gig however does not. I move to my PC. Pop it in a micro to regular SD adapter, and the computer doesn't mount it. It does mount every other microSD of mine though. So can anyone tell me what the hell happened, and how I can recover my stuff?
Actually you can't, your sd card is corrupted and it's known to happen with this device that's why I always keep a weekly backup on my computer with everything. Especially the ones ordered from amazon the high capacity ones as far as I've seen.

And now its not. This is frustrating. I don't want to spend money on a new card dammit.
Try booting a linux live cd and see if you can save anything, thats how I recover deleted tomtom maps in the past.

Is the SD card damaged or can it just be reformatted with a card reader on a PC (fat I am assuming)?
I was about to start using an SD card to backup the internal storage. It doesn't sound like this is the best option and backing it to my PC would be better.
My set up to start was cleanrom 6.2 with envy kernel running fine for a week. I had my sd card disappear today twice. PNY class 10 32gb less than 2 weeks old from best buy. Popped it in my pc and it was recognized no problem. So I transferred my data, formatted in fat 32 popped it in phone, no problem. Transferred data back and was Ok for a few hours. Swapped my battery for a freshly charged one and upon boot, phone said the card was damaged, to reformat it. So, I pulled it out and popped it in my pc. Pc said card was damaged. I opened a command prompt and ran a chkdsk /f and it fixed an issue with the file system. I then proceeded to restore my cleanrom 6.2 backup. So far so good. I am thinking it had to do with an app, but I can't be sure. Upon googling this, it seems that some people have had an issue with external sd cards with this phone.

I'm not sure exactly what brand or model you have for your SD card or when you purchase it. However if its a SanDisk and it was purchased before December 2012 there's a chance that it was part of a bad batch. I had the exact same problem with mine I have a UHs 1 32 gig SanDisk. I read somewhere on the internet that there is a known problem with SD cards from that company built before December. When I spoke with SanDisk they confirm that and said the newer batches have been corrected. Long story short if you're using an ultra high speed or for that matter any card by SanDisk call up there customer service explain to them the problem and they will send you a brand new one. The entire process took about a week for me.

Did you try my suggestion? Ive recovered numerous files using a linux live cd and/or a mac. Try putting the card in a network printer or mem card reader if linux and mac os isnt possible. Ive recovered my files, including those from a 16gb micro sd card, using those methods in the past.
Okay, so it works
Alright alright, i didn't expect this to get many responses. Anyway, it now works. It appeared to be fried, my mac, PC, ubuntu machine, and OG droid wouldn't even recognize that a card was inserted. Nor would my GS3. My solution? after turning it on and off a few times, I just left the card in it and set it aside for an hour. Lo and behold, it now works. The SD now works. It was fried, and is now unfried. I don't know how, I just guess I am lucky. Or aliens. Either way, I am happy. Not gonna jeep anything more than music on it though... Ah well, thanks for the help XDA!
If I were you, I'd back up everything on that card to my pc, and exchange it if under warranty. If not, chuck it, and purchase another card.
Not worth taking the risk again.
Consider yourself lucky so far

So I have had my sd card corrupt a few times now, so far this has seemed to help me recover my data.

The problem could be a sandisk SD card:
(Outside link) crave.cnet.co.uk/mobiles/samsung-galaxy-s3-fault-is-caused-by-sandisk-memory-cards-50010684/
I read about the SD problems after just getting the S3.. decided to get a different brand card from the store.
Hi everyone, I ran into a huge problem yesterday. So I decided to watch a movie, and transferred one from PC to a sd card, then I realized that it's a wrong movie, so I hooked it up again and a message on PC popped up saying that it needs to format my card in order to use it, I used some software to attempt recovery of files that were on the card but they were gone. So I formatted whole card a few times, just to make sure. And when today, I took few pictures with my phone, few hours later, everything on the card was wiped again. Any help, what can be wrong with it? It's a pretty new card too, purchased it around a month ago.

OK...
If you're getting data loss, then either there was a formatting error, or the card is corrupted.
To rule out format errors, download SD formatter (Google it), and just to be sure, do a full wipe again using it. Don't do a quick format.
If you get data loss even after a format using SD formatter, your card is probably corrupt. So go to the PNY support website, follow the steps for warranty claim and get a replacement.
Yeah I've had few data loss even after formatting(around 5 times), I've formatted it thru 4ext recovery and it seems fine, if it occurs again I'll go to Best Buy and talk with them.

I just tried it, it worked for few minutes then phone wasn't recognizing the card.
Hey guys, would appreciate if someone could give me some help on an issue I'm having with a 32 gig SD card (SanDisk Class 10 bought at Best Buy so it's definitely legit). Anyway it worked great for a long time, however, recently I tried to use the Gremlin Remover on my phone, it crashed and burned in the middle of the process as I've heard can often happen with Gremlin Remover. I did a restart, and after that problems began to appear with my SD card. Almost all the data on it disappeared and it started to constantly mount and dismount from the phone. I thought it might have just been the failed Gremlin Remover run, so I reformatted it in Windows, put Gremlin Remover, black hole system wipe, and my ROM back on and did a complete wipe and restore of the phone, card seemed to be working okay, but then the next day it started dismounting and saying it had been unexpectedly disconnected again. Now I can't get the phone to recognize it at all so I can't connect it to Windows to get it formatted. The strange thing is that my tablet (Asus Transformer TF300) can mount the card and read the data on it. However I can't reformat from the Asus since it won't mount as USB storage in Windows. Is it probable that the card is completely fried? Or does it maybe just need a good reformat? If a reformat would fix it, how would I go about doing it? Is it possible to reformat through terminal commands? Or some other way? Anyway thanks in advance for any help.
I too have a Sandisk class 10 uSD card that just recently failed on me. It started losing files one night, then it stopped mounting. Now it just shows up as a 30-something MB drive that I can't format. I have tried many methods of restoring it to no avail.
Maybe try to format it using external sd card reader? microsd to sd?
I think there's a known issue with these cards. I bought one of these a couple wks ago from a deal posted on slickdeals.
I haven't had any problems with mine but after the purchase I started reading comments in the thread about how these cards are known for mount/dismount trouble and high failure rates. I believe in still under my return period with Amazon so I've been debating exchanging it for a different brand like Samsung. Sorry, I'm at work posting on my phone so I can't post a link.

This has already been tried, without any luck. I tried to format via Disk Utility on Mac OS, numerous drives tools under Windows, and gdisk under Ubuntu, and nothing will revive it. Zed's dead.

I too saw a number of reviews that noted the same type of failure, so I may end up giving another brand (like Samsung, as you suggested) my business. Sandisk does not seem to want to take any responsibility for my uSD card failing after only 8 months of normal use.
