"fixing" a hard disk with hdrecover

Mostly so I don't forget. I fixed Midori's windows laptop a while back. After finding 0 viruses and others nasties, I couldn't explain why it was so jumpy and crappy. During the virus scan I'd noticed some disk errors and after fruitless messing with SMART I ran into hdrecovers which reads every sector of the disk and tries to provoke the disk into declaring a bad sector as irreparable. The disk then marks it as such and replaces it with one from its stash of spare sectors.

Surprisingly, after "fixing" about 10 sectors, video stopping stopping and audio stopped being randomly distorted. For whatever reason, these sectors were upsetting windows but they clearly weren't actually important because when they are fixed, their data is lost forever.

I'm about to give it a spin over another disk that had been causing problems.

Disney more evil than I thought!

http://xkcd.com/843/ brought me to this page where I find in the section on how lemmings wrongfully got a reputation for suicide (last sentence is the punch-line):

"The misconception is due largely to the Disney film White Wilderness, which shot many of the migration scenes (also staged by using multiple shots of different groups of lemmings) on a large, snow-covered turntable in a studio. Photographers later pushed the lemmings off a cliff."

I guess somewhere in the credits was "fewer than 1000 animals were harmed in the making of this film".

in reference to:
