I’ve had a Sandisk 64GB MicroSDXC card that I’ve used in my cellphone… I forget how long I’ve had it, but the good part of a year - probably somewhere around 9 months.
And it’s worked great, I’ve really loved how fast the card is. I got one of the UHS (ultra high speed) ones for that reason.
Earlier today, my card seemed to have “self destructed” and I am completely at a loss here. I took the MicroSD out of my phone (it was turned off at the time) and inserted it into an Android tablet that I wanted to demo at a retail store. I wanted to see how some of my pictures would look on the screen and so on.
It worked perfectly fine, but I forgot to turn off the tablet or “safely remove” my card. Incidentally, I had done the exact same thing on another tablet and nothing bad happened.
Anyway, I went to put it back in my phone and it said the card was empty or unrecognized. Obviously that’s not right!
So I tried putting the card into my computer directly, and surely enough it showed as not being formatted. Using the freeware TestDisk, as well as some proprietary partition recovery software - the card only shows up as being 32MB!!! And it doesn’t find any partitions (obviously)…
I noticed, though, that the card now gets very hot very quickly - literally within 30 seconds it’s almost too hot to touch. I don’t think it ever did that before. Is this a sign that the card is dead?
And if so… is there any way to recover data from flash media? I had a lot of really important photos and other things on there that I can’t afford to just lose… warranties are great but I need some way to recover the data as well!

Doubtful, but you can try a data recovery service. Might cost you major $$, and there’s usually no guarantee, so it depends on how badly you want what was stored on the card.
SanDisk will replace the card, but the warranty is limited to the card itself, and does not include any costs of data recovery. Sorry.
I’ve just had a 64GB Sandisk card I bought from Play.com in August 2012 die in much the same way. It had been in my Samsung Galaxy S3 for a few months when today I couldn’t access it. I turned my phone off and removed and replaced the card, when I turned the S3 back on it recognised a blank card. This was on the train into work earlier today. I noticed during the course of the day the back of my phone was hot in the area of the card and when I tried it in a PC when I got home it got hot within seconds like above. My windows PC reads it as an unformatted card of 30.something MBs and fails to format it. Google has brought me here, is this a known fault with Sandisk cards because I’ve actually got another 2 the same, one in my MP3 player and one in my digital camera, I’d like to know how they reliable are because I’d hate to lose more data?
Have the same problem but with my Mac Book Pro and Windows Laptop.
I actually have a Samsung Ultrabook with a MicroSD-Slot, where i used the San Disk Mobile Ultra 64 GB micro SDXC as second drive (SSD only 64 GB). As i had to send my Samsung Laptop for a service, i borrowed a Mac Book Pro from school, which has a SD slot. I used the SD adapter to try if it worked there because i knew i was going to need some stuff from my laptop. Until yesterday it had been working great. Today neither the MBP nor my girlfriends Windows Laptop with SD Slot are recognizing the content.
I’ve noticed that the card gets very hot in only 5 seconds, that’s where i realized that something bad was going on.
Mac Book Pro says that the Medium couldn’t be read. The Apple SDXC Reader Media recognizes only a 32.1MB card. Only Option: Formatting.
Windows Laptop says the card couldn’t be read and only option is to format it.
As the card has very new stuff on it, i would prefer not to format it
Any suggests? Why are so many people having these days the same problems with this card?
The exact same thing has happened to mine with all the same symptoms! I don’t suppose anyone found out how long the warranty lasts on the 64GB memory card??
Hello . I just had same problem as yours . I have a 64GB SANDISK EXTREME MICRO-SDXC that i only used-it about 3/4 times in my camera and now its just NOT WORKING anymore. when i plug-it in my laptop’s card reader , the computer ask me to format the drive but format cannot be completed .
After this problem the total capacity is 32 MEGABYTES . i HAVE TRIED ALL THE POSSIBLE WAYS TO FORMAT THE CARD WITH SPECIAL PARTITION RECOVERY/FIXING SOFTWARE BUT DIDN’T WORK (I’M VERY GOOD IN COMPUTERS ) .
I HAVE TRIED SOFTWARE LIKE ***SD FORMATTER / EASEUS PARTITION MASTER PROFESSIONAL***
SO DON’T LOOSE YOUR TIME BROWSING THE INTERNET FOR METHODS OF /FIXING/RECOVERY AS IT WILL NOT WORK
FOCUS ON WARRANTY REPLACEMENT FROM SANDISK AS DEFINITELY IS THEIR FAULT AND THEY SHOULD REPLACE THIS FOR US AS THESE CARD’S ARE NOT CHEAP AT ALL !!!
