I agree with Munuel, your power supply is probably not big enough to pull
5 drives and two external SCSI cards, plus whatever else you have in the
system.

If you access to one, you should get a digital meter to check what the red
and yellow leads on one of the drive plugs are doing.  I'm gonna guess
that the 12volt is pulling down below 11 volts every time you try to seek
on one of the hard drives.
