[comp.sys.mac.hardware] Hard drives not mounting

) (07/30/90)

I'm having problems with two hard drives, a CMS MacStack 20 and an old
DataFrame 20. Intermittently they can't be mounted. I.E., turn on
drive and mac and the mac throws up it's question mark icon. If booted
with a floppy, the drive still won't mount. Eventually, after cycling
power enough times the drive will mount. This is especially prominent
first thing in the morning.

I've:

o checked for multiple systems
o updated drivers
o reinstalled systems
o reseated cables
o reset PRAM

Clues?
