Once upon a time (or more precisely, almost 20 years ago), I set out to buy a box of diskettes for my Turbo XT. When I returned home, I realized I got wrong ones - Single Sided, and I hastily returned them. Years later I began to regret that, as I have never seen such diskettes since then, and they sure would be a nice addition to my collection...
But a miracle has happened, and I just got a bunch of 5.25" SSDD disks again. Well, I wasn't really surprised to see them practically identical to DSDD, they even format to 360 KB without any bad sectors, the only difference seems to be the sticker which reads "Single Sided...".
So, a question: was this a rule, or rather an exception? Were there 5.25" SSDD disks with magnetic media on one side only? Or with only one hole for the head?
Also, when were Single Sided drives dropped in PCs? I reckon first 5150s had SS, but later 5150s and XTs had DS, right?
