your PS is the problem.

My EB64-275 is supposed to have a 600W PS with a special 3.3V output acco=

nice thing about this is that when the PS breaks I can go to any peecee s=

My 3000-M600-S has a whole horde of drives and has never flinched...

Have you tried the PS from the known good machine in the suspect one?
Also try installing both drives and booting off the RZ.
