IIRC, 1701 is a hard disk problem.

I assume the drive spindle is not accesible outside the HDA. If it is, 
try giving it a tweak (but don;t blame me if it rips the heads off ;-))

Where is this data separator (on which end of the interface cable? With 
an ST412 MFM set-up, I'd expect the data separator to be on the 
controller board. The drive really is dumb...

I've seen those 'contacts' on E-bay....

If it's just the foam, then yes you can mend them with bfoam tape. But 
I've seen one Keytronics keyboard where the foam was fine but the 
metalisation had disapperaed. I have no idea how that happeend...
