Today’s victim, er, example: a Fujitsu 74GB SCSI hard drive.

This was already dead and out of warranty so there’s no hard in this dissection. :-)

One thing I learned from taking these drives apart is that I need a variety of Torx screwdrivers. This was no exception. Other than the screws that held the circuit board onto the chassis, everything else was either a T-8 or T-6 head.

The drive itself comes apart like most other drives I’ve disposed of.

After removing a few screws from the top (some cleverly hidden behind the label), the guts are exposed.

Something interesting is that this drive has a single platter. That, in and of itself, isn’t surprising. What is is that there are two sets of arms that heads can attach to. Only one has heads. (I’ve seen cases with only one head, but two arms in the past as well)

Presumably it’s cheaper to set up the tooling to make one type of head assembly and then decide after the fact how you’re going to set it up. The downside is that you’ll have to deal with the added mass of the arms; adding an extra platter wouldn’t slow down seeking!

There’s the business-end of the drive!

Another thing to harvest from the drives are the super-strong rare earth magnets:

The voice-coil seek mechanism goes in there.

In the end… I have a pile of parts… At the conclusion of this exercise, I want to make some wind chimes I think.
