Try running with your second hard disk powered down (unplugged).  If
that fixes it, then it indicates that your power supply is being
overloaded and is dropping the 'power-good' signal from time to
time.  Dropping this signal generally causes a motherboard reset.

If the trouble goes away when you disconnect the power connector
from your second disk drive, then you should replace your power
supply with one rated for more watts.
