32GB Sandisk Micro SD suddenly stopped being recognized by Galaxy S3 phone

I’m in the same boat - Fall of 2012 bought 2 Galaxy S3s, and 2 32 GB cards - on one phone all is well, on the other it started unmounting and remounting until it was just gone with my data and needing reformatting - can’t reformat in phone, was about to try to reformat with my pc now and it thinks it’s a 30.2 MB card and won’t allow for a reformat.

Solution please!

Simple. Call SanDisk for a warranty replacement.

Yah… truly… I also brought Sandisk ultra 32 GB… its worked great when slotted on phone, but when I plugged it to PC by card reader, it sometimes lost its format, its asked me to format almost everytime i plugged it to pc and i had many times reformatted it because of it…

I had tried to use different card reader but the trouble was still happened… and sometimes it lost from drive when i tried to copy files to it…

it also made my pc get slower and sometimes the windows was not responding when opening it…

how to solve this issue?

Hey all…
I’m a sgs3 (i9300) user and planning to buy a SanDisk ultra 32gb memory card through Flip kart…
But I’ve seen many s3 and note 2 users with similar issues…
So what you guys recommend…?
Shall I buy this product or try something else?

Just wanted to report that I have the same issue with a 8GB MicroSDHC by SanDisk. The card did work fine for some 3 months in my miobile phone (Samsung S4 Mini) but then started to behave like descriobed by all oters in this thread. Also on my PC (W7)  I am prompted to format. I have not done this since I have valuable pictures on it. Is there a way to recover pictures from a corrupt SD card?

Anybody tried this, http://sdcard-pics.digitalphoto-recovery.com/ does it work for SD cards and is it reliable?

Strange that SanDisk is not taking care of this, obviously it happens not only with Samsung.

Maybe wise to use another memory card brand since this problem seems to be so common.

My Sandisk 32 Gb Microsd High Capacity just up and quit on Saturday 7/5. I bought it the day before the Galaxy S5 was released, installed on my brand new phone which has never beed dropped.  I tried all teh suggestions by using a USB reader on my laptop and desktop, using the laptop card reader, trying to read on a tablet, all of which has failed. The tablet refers to it being damaged and Window 8 doesn’t even recognize it. I emailed SanDisk on Saturday and got the auto reply: Thank you for contacting SanDisk Customer Support. You should receive an email response from a SanDisk Customer Support Representative within 2 business days.

Will wait patiently until Wednesday to see if I am contacted.

Who do we contact when this fault occurs? I bought one from Amazon about a year ago and it’s been acting up for a while now, first it kept being dismounted in my S4 and now I can’t even format it on my phone or on my PC as its not recognised anymore…

:smiley:  Hi  Kingmog,

Please, do not grieve more.  Return it, is defective.

Does anyone got a fix on this without sending microsd back to Sandisk.

This just happened with two 32 GB microSD I have but i bouth then on 2012. Don`t think they are going to return this on warranty.

Moreover, I bought in US and I`m in Brazil now.

Thanks

Were you able to recover the data on it?

Were you able to recover your pictures?  I too have a whole year and a half of my kids on my card that just suddenly stopped working!

I never thought it would happen either but I have a whole year and a half on my SD card that just suddently stopped working.  Were you able to recover your photos?  

Same exact issue here, only with the 8gb card.  Does anyone know if there is a way to recover the stuff on the SD cards? 

It sounds like the only option being offered is a replacement.  I also can’t remember when I bought it (and I’m certain I don’t have the reciept).  Does anyone know if there’s a way to tell on the card itself if its date stamped somehow?

Friend, please:

1-  Test your SD card, in a laptop directly to its port-card, (not USB card-reader).

2-  If still bad: in Start / My PC, on the card icon right-click, and then click in Properties / Tools / Error Checking and Repair.

3-  If still bad: try formatting with the tool (portable app, free): USB Flash SD Formatter 4.00
     Then, remove and re-plug the device.

4-  If the card is recognized by the Operating System, the Data Recovery is simple and free.

      Do not do it for Internet, understands me?

      Download to your laptop, this tool (portable app, totally free), configured to use to “one touch”: Recuva 1.51

5-  If there is no joy, then please, do not grieve more friend, return it.

[  I also can’t remember when I bought it (and I’m certain I don’t have the receipt).  ]

You might have a pleasant surprise, if can contact SanDisk Technical Support

Same issue happened 2 days ago in LG D415.  Using card for >2 years.  Successfully transferred card and all data from previous HTC phone 3 mo ago.  Ran out of system memory on LG, so transferred all pics to same 32 GB micro-SD - and hadn’t yet backed up :-(.  While transferring video of grandson’s first steps to card, got message from phone saying that SD card had been removed, and that I should have unmounted it first.  The card was working fine in the phone until that message.  Tried re-seating the card several times and also tried reading it on laptop SD slot and on 3 different USB adaptors - NO JOY (and it’s Christmas!!).  The card is not detected, so there’s no way to use recovery software.   Any recommendations about most reliable recovery vendors? And, everybody says they’re expensive - HOW MUCH??  Happy Holidays to all those without this problem!

No replies to this yet, but I have exciting news!  Based on info from an earlier post in which someone noted that a micro-SD card which had been unrecognized on his phone and computer suddenly re-appeared after several hours sitting in the card reader on his computer, I left my card in the SanDisk adapter on my PC and HOPED!  After ~1 wk of sitting there unrecognized through many hours of opeation and multiple re-boots for various reasons, the card suddenly appeared in Windows Explorer!!  I immediately successfully copied the contents to my hard drive (recovering all the precious pictures I thought were lost!).  When the data seemed to continue to be accessible, as opposed to the earlier report (which said that the card quickly became unrecognizable again), I re-installed the card in my phone - and it has behaved correctly since.  I plan to buy another card for the phone and use this one for long-term storage, but I’ve learned how important it is to maintain a current backup (cloud or another medium) for the removable as well as the internal storage on my phone!  

I don’t have a clue about the mechanism for this miracle micro-SD recovery, but I hope somebody else might benefit from my experience.
