Evotek Winchester Harddisk

The Evotek drive initially used the notoriously unreliable Ampex Alar plated media; whether they ever upgraded to sputtered media is uncertain.  It probably should be avoided.

I would look for an replacement drive using oxide media.  The nice thing about oxide media is it came pre-corroded so that's one thing not to worry about in a 35 year old drive

The Evotek 5000 series is a bog-standard ST-506/ST-412 "MFM" interface. 
  OEM manual is on Manx:


Back in 1983 I had an opportunity to play with one.  Pretty interesting, but very expensive, as I recall--and not terribly reliable.
