The latest drives to fall victim to my screwdriver are 4 of these 9 GB IBM SCSI drives. These drives actually contained the first incarnation of radinfo and were pulled out of the Dell server that served as radinfo for about 5 years. These drives date back to 1999 as can be seen on the label.
It's a much larger drive than modern ones and pretty hefty. There are 24 screws that need to be removed for complete disassembly.
One odd thing I noticed was this large capacitor that didn't seem to be electrically connected to anything on the board (at least I couldn't see any traces leading from where the capacitor was soldered onto the board).
And here's what I'm really after: the magnets. These are really, really big magnets with a very powerful field. You do not want these snapping together with body parts anywhere nearby. For a size comparison I've placed them next to the magnets from the 2.5" 60 GB drive.
With 8 of these big magnets on my workbench now, I have to be careful where I put them and to not let them get too close to each other.
