Last week I was erasing a 2Gb USB thumb while copying some really important shit to my backup disk. I look at the terminal and see it's taking a lot of time to did zeroes on dev/sdb.
Then I realized that dev/sdb is the backups drive and I just erased the firsts sectors of my only fucking backup.
It's ok, I said, let's see what can TestDisk do for me. And it only could find an empty sad partition that had useless shit on it. Whdd couldn't even find the drive. Cat and dd vomited 160Gb of nothing to a file that couldn't be read. I was lost, because I failed doing something I'm really good at. And I did it because I was to stupid to check fstab...
It's the very first time I couldn't recover data, so I'm thinking about delete "Data recovery" from my resume skills and put "Data cleaning. Really effective. I can send you 160Gb of pure horse shit to prove it" instead.
