formatting - I cannot format my micro SD card

I have some problem with the micro SD card I usually use on my phone. I recently updated my phone to Android 6 and it is now asking me to format the SC card.
However it always fails.


I tried to format it in the computer (Windows 10), using a cheap USB stick adaptor. Quick format fails and complete format fails at the end after more than two hours running.


I tried EaseUS Partition Manager to format the card, but had a similar result:



There are some error occurred while writing partition chains on disk.



A Google search pointed me to the testdisk utility, which gave me the following message:


Current partition structure:  
check_FAT: Unusual media descriptor (0xf0!=0xf8)
Warning: number of heads/cylinder mismatches 4 (FAT) != 255 (HD)
Warning: number of sectors per track mismatches 16 (FAT) != 63 (HD)
P FAT32 0 0 1 3852 194 54 61894656 [NO NAME]

On Linux (I'm not an advanced user), the system detects the card but cannot mount it. dmesg gives me the following information:

The card can be used on Windows, I can read, write and copy files on the PC but not in the phone, and I cannot format it in any way.


Any suggestions about what I could try?
