It is not a case of bad cables but maybe cable routing.
Also, four 160GB disks eat power!
I have a box dual athlon similar setup w/ 460W ps
I have to wait for the PS to warm up or there is not enough juice to
properly spin up the last drive. However if I replace the four 160GB's
with four 20GB Seagate's no problem.
You are going to need at least a 400W PS w/ almost no ripple to make it
work. If you have this then check the cable routing.
Also hdparm -i /dev/hdX to see if their transfer rates are reduced.
