I have a problem with my A590 which is getting more and more annoying.
The drive data:
Epson XT 20 MB
60 ms access
Model: HMD-755-002-001
612 cyls
17 sect/track
4 heads
The trouble is (and I'm quite sure of this) is that the drive parks itself
'stuck' approx. 60% of the times I shut the system off. When I start again,
the drive simply can't remove the drive heads from the park position.
This appies if the machine has been off for at least 12 hours. (If I park it
and then access the drive immediately without shutting it off, it works
of course.)
The only 'cure' for this pathetic condition as far as I know is to remove the
drive from the expansion port and expose it light shock, preferrably positioned
upside down.
This treatment has it's drawbacks; right now I have 19 bad blocks in cylinder
611, all of them located at head 0 or 1.
Is it possible to fix this, or would it be a good idea to look for a new drive?
(I have guarantee left, by the way.)
I could stop to park the drive before shutting it off, but I dont't think this
is to recommend... Any suggestions or advice are very welcome!
Please EMAIL me a copy of any postings, I dont't have time to read news for
a week or so.
