[PLUG] backup drive in a NexStar dock

[Denis Heidtmann]

I have a 500GB WD hard drive installed in a dock.  A number of weeks ago
fsck reported pages of errors. A few of you looked at a sample of the
messages and suggested that I had disconnected the drive while it was being
written.  I had not done that (intentionally).  More recently the desktop
reported the drive did not exist.  I powered the drive off, removed and
reinserted the disk, the sata connector and the power plug.  I tried again
and the drive was accessible.  The backup seemed to go normally.  Today the
same "no such drive" message appeared.

It seems likely that the fsck issues were in fact due to a disconnect
similar to what causes the "no such drive" symptoms.

So the possible causes are the sata connection, the drive's connection in
the dock, and the power supply.  How might I trouble shoot this?

Thanks,
