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