Sourcing vintage hard disk drives

So after my dead CD32s returned home I promptly set to using the CD32 power supply to fire up my Amiga A590 external drive. The problem is, like the Commodore PCs of the time, the A590 uses a Western Digital XT-IDE 8-bit 20MB hard disk drive. Both my PC10-III and A590 had these drives, neither are functional.
The 590 however has a SCSI controller. Yippee I thought, easy peasy to get a drive for and I should have some in my stash. First drive I found was a Seagate 2GB unit. After a little persuasion it spun up and the 590 detected it, and formatted it. But it immediately threw a write failure when the Amiga attempted to install Workbench on it. D'oh! Then I went for my only other spare SCSI drives - a pair of Compaq C2244 500MBs from an old Prosignia server. Both gave a tiny thump of the main motors then started pouring out their magic smoke. D'oh!
The question now remains, and it's one pertinent to users of early Macs as well - where the heck do you get old SCSI drives now, let alone old XT-IDE units. Even Alan Gilchrist only had more modern 16-bit IDE drives in his stash
