This is the Toshiba recovery partition.
I also have a toshiba Qosmio X500 for a few days
1. not noticed any data carriers as software
2. the hard disk is shared with a recovery file(s).
3. AND THAT WAS/IS MY PROBLEM: I was asked if I would like to backup my laptop to my external hard drive (640 gb trekstore), when I realized afterwards that all my data was on the ext. hard drive the shock was deep...
4. Now I got some things back with recover my files but completely confused:(
