I think there are quite a few of us in that category, my original HD on a coco 
2 was a 30 meg ST-506 RLL seagate, but it long ago succumbed to stiction and 
alzheimers, as has the 120 meg Maxtor scsi 7120s that replaced it.  But I 
still have a pair of old 10 meg Tandon's St-506's that spin up just fine, 
along with the rest of the machine I used in my office at the tv station for 
all those years.  Those Tandon's probably predate even the coco 2's I have 
several of, along with at least 2 of the old grey ghosts.

So generally, among this group, I expect there are more than one candidate for 
the Guiness Book.
