I messed up my data HDD, with games, music and projects. I wanted to expand my current partition in Windows Drive Management applet but instead, I ended up with deleted master file table. So technically, my files are still there, but unaccessible. In a fucking limbo. Now, I just want to hit something. Very hard. With my head.
I'm glad that I didn't overwrite anything yet, so I can have fun with data recovery. Note to myself... do more backups and use GParted instead.
