I was playing around with the linux command line tool u3-tool to mess with a flash drive. This tool lets you do firmware level things to flash drives that support it. One option was u3-tool -e which supposedly enables the security. It asks you to give it a password to secure the drive with.
What should have happened from here was I should have been able to do u3-tool -d or ... -R to undo this. Instead, immediately after doing ... -e, the flash drive stopped responding. Everything that tried to use it said "Medium not found". Absolutely everything. U3-tool, dd, mkfs, parted, you name it. All giving that same error.
The only reference to it's existence is that /dev/sdb exists, and it has an entry in lsusb. Nothing would make use of it though, read or write. Doesn't even show up in blkid.
Is the drive done for? Or is there a way to save it?

"This tool lets you do firmware level things to flash drives that support it". Do you know for a fact that your drive is one that supports it? I suspect that if u3-tool can't see the drive, it's just bricked. – fixer1234 – 2018-07-29T22:48:48.100
@fixer1234 Yes it does support it. The drive is advertised as a U3 device. I was using it to flash ISO files to the drive's CD partition without any issue. The issue came when I tried enabling the security, and no tool ever recognized it again after that. – Daffy – 2018-07-30T04:57:21.073
