Fedora Notification says my hard drive is failing (solved - looks like it was my thumb drive)

Yeah, that is the point. At least now your system gives you a notification when it sees something fishy! So it probably will die soon.

Understood.

it doesnt show on any system. even in the drivers/disks apps

with failing i just put it on my ubuntu pc and do a through scan/format. 1 hr later i check on it
