A question: when you shut down the system, are you using the Shut Down
command in the Finder's Special menu, or just switching off the power?
The 30-45 second "grinding away" may be due to the drive's having to
recalibrate after a power-off.

Another question: are you sure that power is getting to the drive (green
light on) during these problems? It's possible that the power supply has
a problem (e.g. an under-spec component) that is sometimes preventing
the drive from starting up.
