It might work if it gets detected however most of us are unable to access it in PCs/Notebooks or other phones. I only managed to recover some of data through a media player. I dont have a linux based machine other than the media player so maybe someone can try to see if the card is detected in that o/s. However if sandisk replaced it for me and some other people under warranty then it means it was pretty much wasted.

Yes, i lost my DCIM pictures and was wondering where they went a few days prior to the death of the card. So prob a warning for others if you start losing data on your extSD then it's time to back it up somewhere and wait for the RROD of SD LOL.

Hey guys, can't find anywhere else to put this question..

My SD card file system says Generic Hierarchical... The phone picks up the card fine though. It even works in CM10.

So is it better to reformat the card to Exfat?

Another victim here :(

32GB card died. More than money it's about the buttload of inconvenience. It seems to have happened across ROMs, across memory mfg brands and across classes. Pretty sure it's a h/w fault now.

Totally not cool.

Well I've got to add my name to the list of fried SD card owners.

I was using a Sandisk 32gb SDHC since about mid September when I first had the phone and it was faultless up until the weekend. Suddenly and without any warning, overnight the phone desides that the SD card needs formatting and nothing I could do would bring it back. Computer doesn't recognise it whatsoever and no solution I've found online seems to have any effect.

To add insult to injury, I got hold of a 64gb version of the Sandisk and within 24 hours that one was toast as well. The only difference being that this one is detectable by the computer. Unfortunately, no formatting program seems to cure the card. My desktop, laptop and netbook all fail to make the card work again. I'm obviously going to have to get in touch with Amazon/Sandisk to see about replacements or refunds but I've lost confidence in this phone/card combination on a massive scale.

No issues with my 16gb sd in both my s2 & S3. Maybe it's the higher class models the phone isn't fond of?

I thought its only my problem

[Galaxy S III Q&A, Help & Troubleshooting] akinandroid:
Me too. Lasted just about two months then just died. Tried multiple devices and platforms, in the end it went in the bin. Can't remember what brand it was now but it was a32 gb carried over from my s2.
[Galaxy S III Q&A, Help & Troubleshooting] SpaceGooner:
Just another micro sd anecdote to throw into the mix.

When I first got my SGS3 in May I put a class 2 16gb sandisk micro sd card that I'd previously been using in my SGS1 in it and within a day I was getting card errors constantly. I was about to try formatting the card on my PC, but then I read the following in the SGS3 phone manual:

"Formatting your memory card on a computer may cause incompatibilities with your device. Format the memory card only on the device".

I followed this advice and that 16gb card gave me no more problems.

Then about 6 weeks back I got a sandisk class 4 32gb micro sd from Play.com - thankfully I got a discount and it only cost £7.50. It worked fine for a while but then I started getting intermittent 'card is blank' messages or sometimes the phone just didn't recognise the card was there at all. I don't think the problem in my case was down to a loose connection in the phone itself, which some people have speculated. When the phone didn't recognise the 32gb card, I put my old 16gb back in and it read that fine. I took the 16gb one out again and put in the 32gb one, and once again it didn't read it. The 32gb card still continued to work intermittently, which was a pain as it caused the media scanner to run every time it came back to life which kept draining the battery. Therefore I went back to my old 16gb card full time and I have had no sd card grief since.

For that reason I'm not so sure the problem I had with my 32gb card was down to the phone damaging it - a lot of SGS3 owners have micro sd cards that never develop faults - and my trusty old 16gb class 2 has not so far been damaged by the phone. I think the reason behind many of these card problems could be that some micro sd cards may have tiny inherent faults in their microelectronics that don't show up at manufacture. The fact that my 32gb card only stops working sometimes makes me think there's a 'bad connection' in its microscopic circuits. Maybe heat aggravates this fault, but clearly the card hasn't been fried by the phone or it wouldn't work at all. Maybe 32gb or 64gb cards are less robust than 16gb or 8gb ones due to the cutting edge level of miniaturised engineering involved in them - who knows? :confused:

Yep, same problem with me - Samsung 16Gb class 10 card, Samsung 8GB Class 8, SanDIsk 8Gb and 4Gb... all formatted using the phone... after between 2 hours and 2 days ALL start saying 'SD card removed unexpectedly' and finally screw the memory card so its unreadable and I have to perform a slow format to get them working again.

Sent it back to O2 stating EXACTLY what the problem was... 2 weeks later got the phone back 'nothing wrong with it'. Formatted memory card, 2 hours later 'SD card removed...' AARGH!

my 32GB card was undetectable/unreadeable after a month but luckily my seller allow me to exchange

I have two SG3, one of them was a sd destroyer, samsung sd cards, tanscend and sandisk cards. What I did was change by myself the sd card/SIM slot and since then, i haven't got problems anymore.

I think that in some cases is a hardware issue.

[Galaxy S III Q&A, Help & Troubleshooting] docravi:
my card died too

I am also a similar sufferer. My 32 gb SanDisk class 10 card worked fine fine for 2 months in my sgs3. Then it started unmounting unexpectedly. I formatted it, once in pc and later in mobile but to no avail. And one fine day it was shown as blank. Within hours it became undetectable in phone as well as pc.

Please advise me if note 2 has similar issues because I was planning to buy that.
[Galaxy S III Q&A, Help & Troubleshooting] n3utr1n0:
not only gs3

this issue is not only for the sgs3. the iphone 4s had something similar but with the sim card. it appears that some models of sgs 3 demagnetise the cards or the sim cards. this is due to poor construction or a defect in the building of that specific phone.

Tis the season for SD card deaths...I just experienced mine today. It's a SanDisk Ultra 16Gb Class 10 installed in an S3 that I bought new from Costco this past September. I started to see the little SD icon on top with a message that the SD is unmounted..then mounted..I then noticed that my music play started randomly skipping songs when I played them. Then finally the SD card wasn't being seen. I tried to look at it on the pC or even format it and it is DOA..I had an older slower 16Gb card that inserted into the phone and it works fine. Not a cozy feeling Lucky for me I only store media items on it and I backup the card every other week so I didn't lose much. It does not give one a warm fuzzy after see all these posts though...time to get another one I guess...
[Galaxy S III Q&A, Help & Troubleshooting] POLO_i780:
Its alive!!!

Thought my 32GB Class10 SanDisk was done, it kept unmounting and eventually seemed to have corrupted. Tried to format it on my laptop to no avail, then put it in my S3, 1st time my S3 didnt even read it, so i took it out, put it in again and VOILA! I then formatted it with my S3, as i type this i am loading it with my music and movies, going to see if it lasts, if not then thats that i'll bin it and stick my 16GB Class4 SanDisk back in.

[Galaxy S III Q&A, Help & Troubleshooting] Valwit:
dunno to whom it appears, but there's nothing magnetic in them do be demagnetized by any phone.

i have 32GB sandisk class 10 here that is constantly remounting on the sgs3 too, other phones and computers have no issue with it whatsoever. i would still rather blame the cards, it is possible sandisk had a bad batch.
[Galaxy S III Q&A, Help & Troubleshooting] POLO_i780:
Around 45mins into using my 32GB and guess what? Unmounts unexpectedly, atleast its working, going to pop it into my GS2 and throw in the 16GB Class4 into my GS3 as clearly the 32GB Class10 just isnt getting along with my S3 at all!
[Galaxy S III Q&A, Help & Troubleshooting] BarnOwl:
I started off using an old 8Gb disk in my SIII and had no problems whatsoever. Then I bought a Sandisk 32 Gb 10 SD card from Amazon (The grey/red one). It worked straight out of the box very well for a period of time and then suddenly wasn't recognised anymore......

Took it out and put it in the PC, it worked without a problem so I transferred my data to the PC and formatted the card in the Galaxy SIII.

After that it worked for a while till I put Sygnus on the card......it was not mounting.

Put it in the PC......OK.

So I gave the Samsung Galaxy SIII a factory reset and tried again. It has been working now for about a week but I keep my fingers crossed.....

I think there is definitely something going on here between the SIII and SD cards.
[Galaxy S III Q&A, Help & Troubleshooting] rookiegenius:
I've had the phone and card for 4 months and never had this problem before until tonight. twice... first it said "card is damaged" or something like that. the 2nd time it said "card unexpected removed". All my photos and music were gone (other files like pdf, zip were still there). My phone still regconized the card but just those photos files were gone (I managed to recover them on my laptop). My laptop regconized the card just fine. The card is not dead, only the files were corrupted.Not sure what was going on. I hope this is not a hardware issue.... or else I'm afraid I won't use sd card in my S3 again (which really sucks because that is a killer feature). btw, my card is 32Gb sandisk class 4.
[Galaxy S III Q&A, Help & Troubleshooting] seeding11:
Me too, I am afraid. I lost a 32GB class 4 Sandisk card about two months ago. Like many of you, it started with a "preparing SD card" then progressed to "SD card removed unexpectedly" to "your SD card is damaged" and finally to not recognizing it at all. GParted was eventually unable to see the SD card as well but i did manage to do a backup and try a reformat before it died. My new card is the same as above and seemed fine for a while, and then when I opened the case this morning, "preparing the SD card"..... I am unrooted and currently use the SD to store a few photos and podcasts, so not exactly demanding much from it.
[Galaxy S III Q&A, Help & Troubleshooting] rookiegenius:
I'm assuming there's a possibility that the s3 don't like high capacity card like the 32gb... Most cases were all 32 gb either class 4 or 10.

I decided to save photo to the phone instead. Can't risk losing photos again. I've never used the card much anyway. Only to store some music and files which likely are already on my laptop. But this is not good considering many ppl have this. Definitely the phone itself or its software.
[Galaxy S III Q&A, Help & Troubleshooting] Iamnorthener:
I am not sure it's not the card manufacturer as a lot of the problem cards are Sandisk? There is another thread about disconnecting the connector on the motherboard which I have also tried.

I have to say I have never had this problem in the past with other phones.

This also started since the 4.1.1 update we'll for me it did.

[Galaxy S III Q&A, Help & Troubleshooting] dinan:
Been using a 64gb card (Sandisk class 10) on my S3 for a good 3-4 months now with no problems. Well, when I first got it I had to format it specifically for it to be recognized in the S3 (wouldn't recognize it out of the box for some reason). I flashed a new ROM and everything was fine but I noticed my SD card couldn't be written to. All the files and everything were still there and it can view them fine but now I can't write to the card. I plan on checking the card on the computer later and perhaps reformatting it if needed but is this a sign that the S3 will eventually kill it? Is there a way I can make it able to write to the card without reformatting it?
[Galaxy S III Q&A, Help & Troubleshooting] rookiegenius:
Maybe you should try taking the card out and inserting it in again? And remove the battery. Maybe the rom causes this
[Galaxy S III Q&A, Help & Troubleshooting] dinan:
Yeah I tried that a few times, didn't work. Phone was always able to read it but couldn't write to the device. Plugging the phone into the computer with the USB cord I could also read the files on the comp but couldn't write.

Just now I got my SD card adapter and inserted it into a card reader so I could do stuff directly on the computer and my computer was able to read and write to the card just fine. I ran an error check just in case and it found no bad sectors so I just popped it back into the phone and it works now. Weird...

Galaxy S3, Jelly Bean Stock destroyed Sandisk 32GB

Hi,

It happened to me too. I have a galaxy S3 running jelly bean stock (Nordic version). I have a Sandisk Ultra 32GB microsd HC I. During a day it kept mounting and unmounting, eventually it totally died and now my computer can´t even find the SD card. Lost all my photos and everything... I´m glad I took a backup and formated the card but it seems like this phone have some issues with 32GB sd cards because it worked good for a while with my 16GB but this one didnt last more than 2 months...
[Galaxy S III Q&A, Help & Troubleshooting] winsome:
It's not a 32GB or 64GB or a class 10 issue..... I don't know what the hell it is.... It must be some sort of Samsung hardware fail. Anyways, I stopped using SD Cards any way, because I had enough of this annoying crap.

The issue occurs mostly when coming out of dormacy.

- Sd card unmounted..... mounting sd card......

- Sd card error.... Sd card blank or Sd card unsupported format etc.

The weirdest thing is that I ordered 2 cards, both Sandisk sd cards class 10, and I used one, this erroneous one, and my friend used and still uses the second one in his GS3. I have been having all this headache with mine and he NEVER experienced a single unmount/error/whatever with his card. It's been like 4-5 months. The cards are identical, and the phones are identical and both rooted and both are purchased in the same country...... .

Btw. sometimes a whole week passes without experiencing an error and other times it occurs every 5 minutes and keeps on failing untill the card becomes unreadable.

Luckily I never lost any files as I keep connecting it to a pc, even though pc doesn't read it at first, but I keep disconnecting and connecting it several times untill "all of a sudden" the pc reads it perfectly and then I start copying my files. Weeeeeeeeeeeeeeeird annoying sh.......t.

I bouht only part of the module and i changed it according to the first video, but you can buy the whole module (more expensive) and change according to the second video.

Is easier to change according the second video, just have to unscrew; if you change part of the module like the first video you must be more carefully because the piece is ¿glued? with doble sided tape.

Woot, my 32gb class 4 decided to end its life today (Christmas eve). Before it died, I copied many photos to it . I did a little research on this and actually, SanDisk has acknowledged this as a known issue of the s3. Basicly Samsung only takes responsibility if the card is Samsung branded. It is possible that SS made the S3 only work well with SS cards. I read on some other forum someone said SanDisk said that their new patch of cards coming in Dec 2012 has solved this issue. Not sure how accurate this is. I will contact SanDisk for warranty and ask about this.
