Perhaps the drive is spinning down without informing the OS. I recall
an issue last year(?) about some USB drives not behaving properly
and spinning down without informing the OS, then the OS tries to
access them it gets an I/O error.

All of my 2.5" western digital external USB drives seem to behave
correctly when going into power save mode, have never had an I/O
error as a result of them spinning down.
