[Q] SIII Micro SD card has become corrupt - Galaxy S III Q&A, Help & Troubleshooting

I went to use my phone last night after swapping the battery and it came up with a message saying:
"SD Card is damaged. Try reformatting it"
Its a Lexar Class 10 32GB card so obviously has a lot of stuff on it that I want to try and recover. I've tried sticking it in my laptop but it also complains that it is corrupt and unreadable.
Is there anything I can do to try and recover some of the files before I reformat it?
Also while Googling this issue I came across a topic saying that the S3 uses exFAT that causes an SD card to become corrupt over time and that its best to format the card using FAT32, is this true and if so if I format the card on my PC will this be FAT32?
Any help greatly appreciated!

look for undelete pro or similar wording on Play .

damaged internal storage

I've been having trouble with the sd card in my new RAZR. Just this morning I noticed that I had a new notification "Blank SD Card - SD card blank or has unsupported filesystem."
If I clicked the notification it gave me the option to format but it would never format the card. I was still able to mount the drive to my pc so I made a backup of all the files on the card to my computer.
I did quite a bit of searching on the forum and eventually came across a post that said to try formatting the card with this utility:
https://www.sdcard.org/downloads/formatter_3/
After I did a quick format with SD Formatter 3.1 I then noticed a new notification "Damaged internal storage - Storage damaged. You may have to reformat it."
Now I'm still able to mount the sd card on my pc via the phone but windows doesn't recognize any disk in the drive. I get this error "There is no disk in drive X. Insert a disk, and then try again."
Has anyone had this issue? Any idea what causes it and how to resolve it? At this point, I have a full backup of the contents, so I'm only concerned with resolving the sd card issues and making the notifications disappear.
Thanks
I had this issue, removed as card and blew into the slot and replaced the card, haven't had it happen again so far.

Yeah, I've powered down the phone, removed the card, replaced it and powered back on but I still have the same errors.
Called Verizon and they told me to go to one of their stores to see if swapping out a new SD Card would fix it. Hopefully the problem doesn't happen again.
Stopped by the Verizon store and they swapped out a new SD card. The "Blank SD Card - SD card blank or has unsupported filesystem" error went away but I still had the "Damaged internal storage - Storage damaged. You may have to reformat it" error. This time it allowed me to format the internal storage.
So it turns out that the SD card was completely hosed and the external SD card got corrupted, but after the format was resolved.
I'm still not sure what caused this but I hope it's not something regular as I have had the phone less than a week.
Every time i got a problem with any external device, like sd card, I use this powerfull tool Aconis Disk Director. It has a lot of options that maybe solve you problem.
I've been seeing this too. How do they swap out the internal sd?

[Q] Sandisk Micro SD card won't format

Hi Guys,
I had some problems with my sandisk micro sd card. I am a type of guy that likes changing rome. one day when changing roms, My phone was very hot and i decided to unmount my sd card. after rebooting, i inserted my sd card in and a message flashed: Blank SD card. i clicked on the message and reformatted the card and the same message came out again. i inserted it into my mac and use disk utility to erase the contents of the sd card as all the other options were unavailable. the time for it to erase took longer and longer. after one night, the time increased to a week and then the card wouldent format. i looked at many other forums and the solution to many was sdformatter, which unfortunately did not work for me. when i used my windows to reformat, an error occurred and i could not reformat. i went into device and printers to find it but it was not there. so i was wondering if there is another way for me to fix this problem as this is the 4th 32gb sandisk micro sd card i bought.
Try SD formatter on a different PC, if that fails then you need to buy another SD card or return it the the seller - try another brand if Sandisk keeps failing.

[Q] "SD Card damaged, Format" -- but not really damaged?

"SD Card damaged, format"
I get this error frequently but my SD card is new and not actually damaged. I have to mount the card to access my SD card. How can I fix this error? It is quite annoying and I'm worried that my SD card is actually damaged even though I can still access my files.

You can try and format it in the phone if it has no data on it yet.
I want to do that but I'm not sure which file system to use. I have files over 4GB, so FAT32 is out of the question. The default one may be the one that's causing the problems. Not sure which one is best for an Android phone, specifically a Galaxy S4.

If the Memory Card is 64GB it will default to extFAT. If it's 32GB defaults to FAT32.
Ok, I'll try that, thanks.

[Q] μ files on my sd card. is GS3 frying sd card?

First of all, im using a 4.1.2 stock and my device is rooted
So i had an Sandisk 64 GB class 10 for some time which one day became a "read - only" card...
So afterwards i bought a Samsung 32 GB class 10 which I found out also had problems because i could put about 10GB of files and everything more that 10 GB turned into wierd folders that their name starts with "μ" and there where no actual content inside and i couldn't delete them.
So now i'm at my third try, again with a Samsung 32 GB class 10 which also has the same problem, only now i can write on it about 20 GB of data before files start to get curropted.
Just want to say i bought all 3 SD card from Ebay, and though i guess they might be fake (tons of bad luck), after searching the web I found out there are many GS3 users with the same problem...
So i just want to put an end for this question..
Is GS3 frying SD cards? is there something i can do to stop it from destroying SD cards? can i fix somehow the SD cards?
thanks alot!
Hi! when you are asking a question you should include details such as operating system(4.1.2 , 4.3, 4.4, stock, rooted and so on) and file system. I noticed while searching google that the majority of "s3 fried sd cards" so to speak are sandisk and in your case it seams that there is no such "limitation". Maybe if you give more details someone might be able to help.

not sure. I formated it with my GS3 and the computer won't recognize it without reformating it.
Worst case scenario is your phone somehow corrupted the sd card and that is that. I had a similar problem with my usb flash drive which i used on-the-go and unmounted it before removing it but when it happened i didn't make a backup(as always) and got stuck with a nice keychain. If you have the possibility to format it under windows with a card reader and choose fat32 at least you have a working sd card, otherwise use your warranty for the sd card(if you have one) and always BACKUP.

but do you think that my device is malfunctuning in a way that will keep frying my SD cards..?
well since this is the second sd card i personally send it on warranty(as hard as it may be without the phone) because it seems that something is not right with the contacts of the card reader circuit board. I read somewhere that on some phones the card reader slot had some contacts partially detached and so the sd card kept getting corrupted. Search a bit on google about this issue and take into consideration using your phone's warranty. Best of luck!
That is a bit strange. Unless you're used to remove the sd card with the phone accesing to it (no safe removing) or removing the battery while the phone is running, that's absolutely not normal.
I have my 32GB sd since 2010 and I never had any problem. I formatted it this year because it had tons of useless data and I liked to have it clean.
Of course it's not from Ebay! That is bulls**t and use to fail suddenly.

[Q] SD card formating aborts abruptly, anyone can help?

Hi partners! This is my first post here.
I have a Moto E LTE, installed Surnia on it, and it worked perfectly until now.
I've been using it only with the internal Storage, but now i wanted to expand.... so i bought a Kingston 16GB Micro SD Card Class 10.
I turned off te phone, inserted it, turned it on. The card was detected... I had to pick between using it as a Internal or External storage... and here's the thing. Either option follows with the formating of the card, and in both cases, the process abruptly ends at 30%. After that, the card is no longer readed by the phone.
I can remove and reinsert the card, and it will read it again, but the process still ends abruptly at formating.
Any clue? Any help?
I would be very thankfull.
I've search previously to make shure no one else posted the same question and i didn't find it. If it was answered in the past, im sorry i didn't find it.
Thanks so much, and excuse my bad english.

Hey Pablo, 2 cases, bad formatting or bad card. Use a Card reader on your PC and format the card separately using FAT (choose the full format option), this will help identify if the card is physically damaged, if all's well, then put the card in your phone and choose the formatting option and most likely should work. If the formatting fails, most likely you have a bad card, google for other low lever formatting utilities to see if they can identify any bad sectors on the card.
Use Caution read up on what Internal and External storage well before you choose one of the options. Search for term Adoptable storage on Marshmallow and should give you a good idea.
