Hard Disk Recovery Video
Another data recovery on a non-spinning drive (I convinced it to spin again with some tweaking), I decided to run a few seek operations and get some footage of it. The heads on this drive, likely a 4200RPM disk, from Fujitsu can seek from point to point in less than 12ms. For those of you unfamiliar with hard disk mechanics, it is this seeking behavior that causes the “clicking” noises you hear when your drive is accessing data that is not sequentially organized. The disk heads themselves float off the surface of the disk at a distance of less than 100 microns (not visible in this footage). The smallish projection at the end of the element is used to raise the read-write heads off the surface of the disk when they retract and the drive shuts off (to protect your data in the case of a fall).

I personaly think that Recuva is better than Restoration, but u can have your own oppinion. Recuva (pronounced “recover”) is a freeware Windows utility to restore files that have been accidentally deleted from your computer. This includes files emptied from the Recycle bin as well as images and other files that have been deleted by user error from digital camera memory cards or MP3 players. It will even bring back files that have been deleted from your iPod, or by bugs, crashes and viruses! Download link for recuva (freeware): www.filehippo.com Please comment, rate and subscribe!
