My shiny new Galaxy S III has now destroyed two 32gig micro SD cards on me. About two weeks after I installed the first card, my phone started giving messages about the SD card being improperly removed, then it would immediately try to re-mount it, then would say it was removed again, then finally started just repeating the "unable to mount SD card" error until I physically removed the card. I argued with best buy to give me another one, and now today (about two weeks after installing the new one), the same thing happened. I put the card into a USB reader to try it on my computer, and now even my PC does not recognize the card.
Has this happened to anyone else? What can I do to fix this?! I pre-ordered the phone from verizon, so I'm now well out of warranty replacement time.

I have a 32gb MicroSD card and haven't had a problem. I do wish I could use it more as internal memory rather than hardly usable external storage...but that's a different issue.
Sorry I couldn't help, but just wanted to say that Galaxy S III does support that much external storage. Maybe a hardware issue? Try troubleshooting it with another MicroSD card.

Gotta be the cards you're getting I would think. I had a 16gb card that came with my Droid x almost 3 years ago in it for almost 2 months before the card finally crashed.(I'd abused that card tho, carried it in my jeans pocket, left it sitting on my table etc) Then I put my 64gb in it. It's been a little over two weeks now and no probs with it. I've written too it and erased and so on so I've actually used it. It's almost full now actually lol.
I have that same 16 GB from the droid x. Do I still need to format it if I flash a ROM? And how do I check what format its in

My 32gb card was doing that on stock until I finally installed a custom rom. No problem since.
Synergized GS3
SD card gs3 issue
I also had trouble with my external 16gb card after flashing 2 ROMs (synergy & beans v9). I was not even able to get a computer to recognize the sd card after the flashing.
I thought it had to do with using a stock, then rooted stock, then custom kernel. i thought the combination and repeated TBU access over a 4 day period just trashed it. maybe there is more to the story?
1) What is your ROM flashing history (what roms, how long were each installed)?
2) Which rom did you notice the problem on?
3) Were the original and replacement cards the same make/model?
4) What format were the cards in (FAT32, exFAT, or other)?
5) are/have you overclocked your cpu?

Thanks for the responses guys. I'm still fully stock, I haven't done anything to the phone (yet). I don't know what the format was, I just put them straight into my phone and let it do whatever it wanted to do. The original and replacement are the same make and model, from the same store. So before i panicked too much, I was considering buying a new/different card from amazon and seeing if it does the same thing still.
Just didn't know if anyone else was experiencing this, or had any thoughts on why that would randomly happen on a completely stock phone?

That sounds like your best bet. There are plenty of crappy cards out there. My ADATA 8GB class 10 has been great so far. I have noticed that the GS3 gets really hot right near the cards (micro sd and sim). Can't be great for the cards long term.
I've had my VZW GS3 since 7/5 and have been fine with my card. I've seen plenty of people who've had trouble with FAT32 vs exFAT, but none who have lost their card.
I have seen a ROM break cards before (an early AOSP gingerbread build for the Fascinate claimed one of mine), so I've actually been looking. This is the first thread I've seen.

I've also noticed it gets really hot toward the bottom of the phone. Now that I think of it, both times I noticed the SD card issue right after taking the phone out of my pocket. Maybe it's just getting too hot? I wonder if my case is also holding in a lot of the heat and making it worse? I wish there was a way I could test things without breaking an SD card every time!
My GS3 fried a new 32gb card that I put in it after about 3 weeks. Randomly got an "unreadable SD card error", can't correlate with any specific activity. I reformatted the SD card & it works again in the phone. I was rooted, running stock at the time. Maybe it's the heat, but I don't recall it being hot at the time (I also don't recall it not being hot...)
Try sandisk.I was having problems with lesser brand

I have been using the 32 GB San Disk brand card that came with my thunderbolt and it's been working great.
I really don't know what could cause that to happen to a card and I haven't noticed any other reports of it happening with this phone.
If it comes down to it VZW SHOULD give you a replacement because it could be something to do with the card slot in the phone. I would try talking to them if you can't get it worked out.
So going on the theory that maybe it's just getting too hot, I just ordered a 16gig sandisk ultra micro SD card. It claims to be "temperature proof", whatever that means. Hopefully that clears things up, otherwise I'll have to deal with Verizon, and I'll be super mad if they give me a refurbished phone when this issue actually started two weeks after I got the phone.
If I don't post back here then you can assume all has gone well!
16gb card from droid x
same as others, used the same 16gb card from my droid x, transferred to the bionic when it was released, and now have been using it in the GIII since release. no issues.
I don't believe the phones are getting too hot to do the damage. The hottest temp my battery has gotten had been 106 and they say that heat damage isn't even a concern until around 140 or so. I would think the cards could take the same if not more than the batteries.
I had a similar problem, my sd card wasn't destroyed, but it would randomly become unmounted. It started happening after I hooked my phone up to my corporate email and it forced me to encrypt my device. After I removed the corporate account it stopped happening. This was all on stock TouchWiz from the factory.

I have had my 64gb SD card for a month and so far nothing went wrong. did you buy your SD cards from a reputable source? I have always used sandisk SD cards try buying one from Sandisk or even Samsung. if you bought your card from ebay make sure the card works, I have heard that some times people sell damaged cards for very cheap. But other than that good luck.
16 GB class 10 sandisk 30 mb/s version died on me with this phone after 2 weeks, stock ROM, formatted with phone. It was brand new.
The error I had was it became read only. And no it was not fixable, I tried everything. Low level format, checking permissions, different OS's, putting it in SD adapter and messing with lock switch on there.
I read class 10s are more prone to die quicker and aren't necessarily better, but just different from a lower class. Ie a lower class will last longer because it read and writes differently and doesn't skip certain safeties like a class 10 does.
Running a class 4 16gb sandisk now and it is annoyingly slow.

My SD card gets corrupted every time I reboot my phone. I'm using a 32GB Sandisk Ultra formatted as FAT32. The phone has CleanROM 5.6 installed (I've wiped, redownloaded, and reinstalled the ROM a couple of times).
Any ideas or experience?
Probably going bad. Mine did similar things when it was going bad. I formatted and did every trick I could find online many times to see if I could get it to work, nothing worked.
I ended up getting it replaced by SanDisk. Pretty easy to work with and I got it back within 7 business days.
I keep all my roms and zips on my internal and do not flash anything on my sd card.

Does the card work anywhere else? I had a Sandisk Ultra UHS-1 Class 10 go bad in mine as well. Some of the research I did I found out it was a common inssue with those kinds of cards, especially if they were exFat because of the way Samsung uses their own proprietary exFat system.
I've done a large write+verify using it in an SD card slot on a laptop and it worked fine. The card is only about a week old, and it's done this since the beginning. I don't expect Sandisk would replace it since it works fine in Windows but not my phone.
They should replace it. Mine was mounting and unmounting over and over again. They didn't have any problem replacing it. No reason not to call. The only downside is a no or if they say yes, you will be without the card for about 7 days.
Sent from my SCH-I535 using xda app-developers app
If it's only been 7 days, take it back to the store or order a new one and then send this one back. That being said... I've had 3 32GB sandisks go bad in my phone, to the point of even being corrupt in Windows. I'm using a 64GB now, and knock on wood, it's been working fine for about 2 months so far... There have been a few threads about cards going bad in these S3's. Dunno if it's just coincidence or what.
I bought it from Amazon and have done a lot of returns there lately, so I contacted Sandisk. They agreed right away to replace it, so I'll do that.
Thanks for the suggestions.
Did you buy it online? If so it might be fake. Read more by googling fake micro sd. Apparently they make a 1gb memory card look like 32. It will just overwrite itself making data corrupt
Had the same issue with the same card. For me it was a hardware issue. When the card is inserted it clicks and comes back out a little. On my phone it came out a little too much and was losing connection with the card over and over and telling me the card was corrupted. All I did was push the card back in until there was resistance from the locking mechanism. Haven't had an issue since.
Now I say it's a phone hardware issue but really it could be that the card is too short or the cut outs where the locking mechanism holds on to are too low.

I got it direct from Amazon, and it held and verified 30 GB of data with no problem. It's definitely real.
I have the new SanDisk 64GB micro sd card, and lately ive been getting 'Damaged SD Card, Try Reformatting'
at first I just sighed to myself.. 'the s4 if another sd card destroyer'. I checked around the forum, but didn't see any similar topics, so I thought maybe it was just me.. but now my buddy who got an s4 on t mobile picked up one of the 64gb sd cards, and just got the same notification.. so what gives? *(pic related)

I've heard a lot of people having problems with the Sandisk cards. Myself included, my 16gb I had in my S3 got totally messed up.
I tried reformatting and it was a no-go, totally dead.
Since then I bought a 32GB Class 10 Samsung Card. Never had an issue since.
It may have to do with the formatting of the SD card. While playing around with my new Samsung 32GB card, I found my S4 displaying that message (even though it worked fine on my computer) every time the card was formatted as exFat. Fat32 seems to work fine.
I have that same issue, however, it also happened to me with my S3. I ended up have to format the card in the phone and copy everything back onto the card again for it to work. so far it's okay right now. This is still the same card, Sandisk Ultra 64gb micro SDXC. Both my wife note 2 and buddy S3 use the same type and they never had any problem with "damaged sd card". I'm thinking OP and I both are just the bad luck one with a bad card or two. I'm thinking of calling in for warranty from Sandisk to see if it's the card that's damaged.
This issue happened to me, but only once. After the OTA update, after reboot I saw this. But instead of formatting like the message suggested (I already had gigs of stuff on the card), I went into the settings and Dismounted the card and remounted it.
Haven't had an issue since.
Maybe you can try it to see if it works for you.
My s4 has been fine with it but when I had a skyrocket it was having major issues.

It is best to format fat32...period, no issues will ever occur. I have been using a 64g since it hit the market...it is so old there is no markings left on it..hehe
S4 here and 64gb class 10 that originally was in my S3. No problems yet. Think I might be fat 32.

This is a common issue in all devices with sd's, especially devices that move physically.
Put 1 or more pieces of scotch tape on the non contact side of the card and cut to size. This will reduce the amount of movement of the card during write events to the card, which is the culprit of why these cards get corrupted.
Thats it.
32 gb class 10 lexar fried. Never had a problem until now.

I'm glad I'm not the only person who is having this problem. This thing destroyed my 16gb lexar that I've had for a few years. Mount option went gray, and I couldn't even open it on the computer. I was trying to make sym links to move my Google Music to it, but yeah. It's a little disappointing, but I wanted to get a 64gb anyway... Is the secret to use Samsung SD cards? Either way, it was time for a new one.
you know you could use the PC command chkdsk -r -f to fix damaged sdcards?
from what i've been reading about the 64gb sandisk cards, they work better formatted as exfat than fat32. samsung is one of only a few mobile phones that support the exfat format. when you try to format a sandisk 64gb class 10 card, it will eventually become corrupt. that's why they come as exfat. also, formatting it to fat32 will indeed slow down the speed transfers of the card.
this tool i hear works good for changing the format from exfat to fat32 without damaging your sd card. http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm

I will try that when I get a hold of it again along with disk utility when I boot up mac next, but currently it's blue screening my laptop when I try to use it. (Running a bootcamp of windows 8 means weird bugs are lurking around every corner)
Happened on my Note 2, guess these new Samsung phones don't play well with SanDisk cards.

Friends s4 didn't like any brand but Samsung. I did however notice a lot of bad reviews on all 64gb micro sd cards except the Samsung one. Based on the reviews I bought the Samsung 64gb class 10 and had zero issues. A bit more expensive but you know what they say.
My 64GB Sandisk Class 10 has been damaged 3 times since getting my GS4. I sync my 40GB of music and takes all night to do this. It can be annoying, but when it happens I re-sync when I go to bed.
I ordered a 64gb Sandisk SDxc card from a reputable place and I have had nothing but issues getting it to work with my phone. Tried re-formatting to Fat32 and everything else I could think of. I got a replacement card from the seller and I'm having the same issues with the replacement. I sync music to the card and it shows on the computer initially, then after insertion into the phone most of the data disappears. This happens if I use the adapter and if I try to sync via a cable. The card is a class 10 and UHS speed class 1. Any suggestions?
It happened to me that I lost all info stored in my SD card, I took it off with phone also off because I needed to swap sim cards, then after reboot, it appeared a message saying "blank SD card inserted"
I suppose it is probably a good sign I'm not getting overwhelming replies on this topic. I got my money back and will try from a different seller. Maybe they got a bad batch? who knows.
I'm using a class 10 samsung 32gb without issue
I was having same issues with a SanDisk ultra 64, however I have no problems with a SanDisk extreme plus 64g. Just for a test, I borrowed a SanDisk ultra 32g. Did not have any issues. Maybe I had a bad card....

I got it off Ebay. I ended up getting a refund. I tested both cards and it looks like they are either defective or more likely bogus. I'll be buying from a reputable source next time around.
Every time I swap a battery from my charger into a phone, it does not recognize the SD card. I power down and then swap the battery. It again recognizes in a day or two. Anybody know what could be the problem? This is Sandisk 32 GB. Worked fine with my S4.
Have you tried reformatting the card yet? I had a similar issue when I went from the Streak to the Note 1. I eventually reformated the card and it stopped happening, but the card failed completely shortly after. Not sure what happened. Everything was normal before I switched phones and seemed normal (for the couple of weeks befored it failed) after I reformatted the card.
