Hi Erich.

Okay. I have a chassi fan that is quite close to the drives, I will
try disabling it. I've also ordered two Nexus TwinDisk anti vibration
harddrive mounts with which I'll place the disks in my 5.25" slots
instead, away from any fans.

If this doesn't work, I'm stumped, as I really don't think it's the
power supply and I don't have the money to buy a new one.

Of course, I understand this. Just trying to figure this problem out..

I'll report back with my findings with moving disk away from fans and
using anti-vibrations mounts.

Thanks for taking your time to reply.
