Am I correct in remembering that the Syquests of that
time used the
34/20 pin MFM-hard-drive "ST506" interface?
Yes, this is correct. I
have a small Syquest removable hard drive
here that I used for just long enough to figure out that it was
unreliable as all hell. I last powered it up in about 1990 or so.
It has a standard ST506 interface.
Unreliable? Hmm.
My father worked at a typesetting firm in the late 80s and early through mid
90s, they used Syquest 44MB cartridge drives. Yes, they were horribly
unreliable. They'd probably be OK for home use, but it was a fairly normal
occurrence to call the service agent in because the drive had stopped
working, or they couldn't retrieve data from a cartridge. On several
occasions, the service agent would fiddle with the drive, and replace the
cartridge, causing the drive to make a very loud scraping, squawking sound,
which turned out to be something ripping chunks of coating off the cartridge
platters. The agent seemed to use whichever cartridge was closest to hand
for testing; on a couple of occasions, he destroyed cartridges that
contained vital client data.
Most of this info is second-hand, but my father would often come home with
stories of the day's Syquest or Mac-related disasters.
