Cannot access USB pen drive

Hello. A few days ago I've inserted my pen drive on a Linux Mint computer. The pen drive was recognized OK by the computer. I ejected it and I inserted it again on another USB port. The pen drive was not recognized by the computer. I've plugged it on my Windows 8.1 64 bits computer but it is not recognized. I cannot format the drive. I can see the drive on Explorer but the file system is "unknow".
I would thank some suggestion.

You may have formatted it on Mint using EXT4 or another Linux file-system. Those file-systems won't be recognized by Windoze OS's. If you want to have the file-system usable by most OS's, you will need to use one that can be used by all OS's. Common would be FAT32, but that has some disadvantages like no redundancy and a max file-size of 4GB, or NTFS, but then on someolder Linux versions, or probably also MAC OS's, you might not be able to access or at least write to it without extra software or 3rd party tools.
>>   I cannot format the drive  <<  this is because the drive is not recognised
maybe best to reinsert it in the linux pc, then use this  to format it  as fat, or ntfs :

Thanks to nobus and rindi. The Linux Mint computer was loaned to me in a conference and I cannot access to it. I've plugged the pen drive on my Linux Debian computer. It is not recognized. Gnome filer shows "XXXXXXXX U167CONTROLLER"

fdisk command only shows the HD and not the pen drive.

mount command shows:

Do other USB sticks get recognized on your Debian PC? It may be missing some modules. I'd boot a PC using Live Media, like Knoppix, and then try using that to check your USB stick. If you also get problems then, I'd say the stick has become defective. USB sticks tend to fail quite often.

My Debian PC works fine with others USB sticks. I've used Parted Magic Live CD that recognize other USB stick but not the one USB stick that fails. I see:

udevil: error 63: no media in device /dev/sdb (or specify type with -t)

It looks like the pen drive is damaged. I'll wait two days if there are another suggestion for closing the question.
