Man that is foul ... I too started in the business doing repair, at a local
shop, and we definitely saw some dirty ones, but never like that! The
grossest stuff was always out in the field particularly some of the

Once upon a time, it was the job of the OS to take this badblock count
and remap blocks itself since the drives themselves weren't smart enough.

In the early days, particularly when actual ST506 and ST412 were common

Hi Pontus
Thanks that clears up one or two things.
I worked on a straight 8 with its clear cover on top along with a couple

Whilst at DEC 1975 onwards I saw loads of 8/a's and the odd 8/e lurking

As far as I can remember I never saw
