Hi guys  , i purchased a Sandisk Ultra 64Gb  2 weeks ago , i have been using it fine for a week, yesterday i plugged the microsd into the SD adapter and plugged it into my laptop, the laptop took about 2 mins to detect it in Windows 8 but only as a hard drive, it would not open the drive nor could i see any files, 

after about 5 mins of messing about trying to get it to work ii gave up, when i tried to remove the card it was literally too hot for me to do so,  i have to power off my computer , wait a few minutes and then remove it ,i looked at the microsd and it now has a crack in the microsd, i am really just trying to find out if anybody else has had anything similar happen

i have been using memory cards for years and never had anything like this happen before, it could have been very dangerous and the outcome far worse.

I’ve been around here for a while, and have never heard of this before. Could either be a defective card or the SD adaptor itself that fried the card. :cry:

Hi Tapeworm, thanks for your reply, i am going to contact the people i purchased it from, see what they have to say, it could have been extremely dangerous., i have just inserted the microsd into the sd adapter again this morning and plugged it into the laptop.it is doing to exact same thing, regarding heat so they can have a look for themselves at the problem

I had same problem with 64 mobile ultra.
Very hazardous. Could burn and create a fire.
San disk be careful.

I have the exact same issue, im using a 32gb for the Raspberry Pi , worked fine for some weeks. Then suddenly it wont boot.

I burned my fingers on de SD-Slot. When it cooled down i took it out and it was slighty bend, wit a fine crack on the top. The card is useless at the moment. Im afraid to use the 64 one in my drone . 

Who has the same experience , with a faulty overheating card ?

Had the same issue with the 64gb Mobile Ultra micro SD and can’t get my tablet working again: it overheats with any computer/adaptor/laptop. Can’t even format it. Daren’t put it in my phone. Has anyone in Sandisk admitted to this rather serious fault?

Well it’s Feb '24 and I just bought a 3 pack of 32 BB Ultra usb3 and they get very hot. Seeing as this has gone on for so many YEARS I won’t be buying any more. There are tons of other brands. I expect they won’t do anything seeing as they haven’t done for so long.
