Sure I can pop another drive in there and test it.   The above drive 
is probably 5 or 6 months old, but when I remove it I will check the 
manufactured date for you.

No I don't think it is distro specific at all.  Probably some weird 
bug.   Like other users have reported, it comes and goes.  That in 
itself suggests either hardware or timing issues.

Something along the lines of:-   Software requires an input from some 
hardware.  Software gets interrupted and misses input.  Hardware has 
no way of knowing that the signal has been missed.

But this scenario poses questions of its own.
