Hard disk read/write operations

After performing a 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 7200RPM disk, from Toshiba 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).

What are the names of both of them songs????

PLEASE TELL ME!!

[APOLAUF]

The first song is "Weak" by Galen Behr. I'm not sure about the second, but I'll post it when I find out.

When you were working with the drive did it make a sound similar to 120Hz? If so then it is a 7200 RPM hard drive.

[APOLAUF]

I'll have to check the label on the disk. It's probably either a 4200 or a 7200.

I heared that,once opened,hard drives are inoperable. how can you still boot windows from it?

[APOLAUF]

This isn't exactly true. An opened hard disk becomes extremely vulnerable to dust and other elements which will cause it to fail rapidly. However, many drives can operate for a while before sustaining environment-based damage. This drive did not boot windows (though it could have done so easily). Rather, it was accessed from another machine. In conclusion, drives are sealed for a reason, but can still operate when opened, to a small degree.

this will never cease to amaze me, how we ever got to create such things... awesome, simply awesome.

[LordShivasServant]

Fuck off... no way... shit.. wow.

That's fucking fast

I prefer having this mechanical masterpiece than an SSD in my machine.

@judck I would recommend Spinrite, but it is not free ($89).

[i90east]

Another piece of computer technology that's way beyond me. I have no clue how they get this to work.

WHAT ARE THE TWO SONGS CALLED?

[judck]

Can anyone suggest an util to test disk surface? I need one that can stop and resume later. These days drives are huge and it takes hours to complete a full check.

[octavdesinger]

that is the real reade/ write speed of all the hard disks in the world
