hello i have just but a micro sd card and it is very hot, and i can’t read it with the computer
Dear member of SanDisk Community, welcome.
Test your microSD 128 GB, in other laptops, directly to its port-card (not USB card-reader).
Also, see what capacity and format, have in “properties”.
In PC, use only USB card-reader of brand, of high quality (SanDisk, Kingston, Lexar, Samsung, etc).
Because most and the cheap, are junk, not have the chips.
Luck, and then you tell us, what happened, please.
Regards, Alfred. (Google translated)
if the card is getting very hot it will need to be replaced. contact sandisk support.
