I've seen similar situations when when drives, for whatever reason, just 
want to go to sleep. I have a server with seagate boot drives that just, 
well, spin down unless they're told not to. Note that modern drives 
will, sadly, try to learn from your behavior and then set their default 
power savings accordingly.

I'd suggest reading up on hdparm, and then setting your drives to 
absolutely NOT timeout whatsoever. Then see if you have the same issues.

This works for me:

hdparm -S 0 /dev/sdb

...but use hdparm at your own risk.

If that works, put in your rc.local, set it to be executable, and forget 
about it.
