Hard disk read/write operations #2

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).

Looks like alot of bad sectors. i can see from experience that the arm flicks to the centre to read the relocated sectors!

Actually, this disk was perfectly okay - it had a stuck head, which is why it was open - I was running a disk-wide search in order to make the head move as much as possible. :)

how long did it last opened?

[APOLAUF]

Probably somewhere between 30 and 40 minutes, I think, possibly a little longer.

sometimes reallocated sectors are stored on the outer RIM, i am SURE that is the case in desktop 3.5 drives

winter by aril brikha i think

And the fan mast suck air from the clean room, of course...

It's "Winter" by Aril Birkha (some have it spelled "Brikha")

I second that what is the name of this fine tune. And great video.

[Mag1cWind0w]

What is the name of the music in this video ? It's a nice song !

if you got a fan, keep it blowing at the disk so no dust gets under the heads or on any parts. It'll last longer also that way.

Just long enough to recover data! older ones last loger because data density is not as high.
