I wonder if there's anything S.M.A.R.T. information can tell you.

There is a spinup time test, and I wonder if perhaps there is SMART
logging within the drive that could reveal a problem with the drive not
spinning up as quickly as it should, and maybe that is causing a
problem (somehow).

Keep in mind that not all USB docks will properly support SMART.

This may sound dumb, but does the drive _sound_ different when first
powered with the system, and does the sound change when it is mounted?
Does it sound like it's "waking up" only when you manually mount it?
