I just dug up a USB drive from 2007. It's ext3 fike systems, and there's just one empty file on it, called 'do-not-forget.txt.' No clue what it means, or why I even made it.
@nixCraft Weren't technologists hiding encrypted file systems in the high-address unallocated areas of ext3, around that time? You might see if there's a hidden filesystem in addition to the ext3.
But, it'll probably need a pass(word/phrase/key) from around that time, too.
@nixCraft My money is on hidden encrypted file system. You have failed past you.
At least it predates bitcoin so it's probably not a lost wallet.
