Yeah. That's me backup in a backup in a backup >>>
Seriously I had my full music library nested 3 times over. When I backed up, I left the main folder on the other drive and absorbed it into the next backup as so on. Very sloppy management on my part.
Now that I have a new laptop and am retiring the 5yr old desktop I plan to manage data much better.
Not that I have a choice on a 120gb main drive and a 160 external versus a 300gb+80gb + 160 external.
Too many drives just make for a mess of data.
