I have a two-year old CMS MacStack-40 external hard disk which has been
behaving funny for almost a year now.  During a given session, the
read/write indicator light (which blinks only during a read or a write) 
occasionally stays continuously lit and the disk stops communicating
with the Mac Plus.  Sometimes this happens during power-on also.

Fortunately, I have been able to get the disk working by simply shutting
it down, shaking the scsi cable once or twice and then turning the disk
on again.  This usually works.  When this procedure fails, I simply
disconnect the disk from the Mac Plus and immediately reconnect it;
the disk then works flawlessly.

I had sent the disk back to CMS twice when it was under warranty.  Both
the times it came back with "no fault found" label. 

I don't know whether the disk has gone bad or whether the scsi cable needs to
be replaced.  Has anyone else encountered a similar problem ?
Is this a common problem with CMS disks ??

I'd appreciate any suggestion, comments or information regarding this.
Please reply by email.  Thanks.

Prashant.
