Sorry to dig up old stuff here but after replacing hardware and
pulling my hair out to no end, I traced the source of the problem out.
On every drive in the array, the points on the PCB which the contacts
for the drives motors and head/actuators make contact with were
oxidized enough to cause the issue. I ended up pulling the PCB off
each drive and cleaning them as well as cleaning out all other cable
and drive connectors from the HBA outward and everything is happy
again.

Good job, that was quite unexpected :) Are you next to the
seashore?
No. I'm up in NW Ontario in Canada actually, far away from any salt
water. I'm guessing it was from the combination of air
pollutants/humidity and heat given the drives are not in the most
hospitable environment esp during the summer ... but after cleaning the
board contacts up as well as the esata cable ends/ports, its working
great again.
I'm beginning to think when I do replace any drives, after warranty is
up on them, pull off the PCB, clean it up and coat the contacts with a
good smearing of dielectric grease to keep the issue from happening.
Makes me wonder how many other people out there suffer from the same
issue given the amount of unresolved similar hw errors I've found while
googling the errors..
Thanks again,
Andrew
One other thing might be worth noting, before I cleaned up the oxidation
on the drives boards, they would work fine if on dedicated SATA channels
off the mainboard, but when put on any sata port multiplier, it would do
nothing but act up. Which was really weird.
I'm assuming there must be some inherent sensitivity with sata PMP
chips/hw that make this more prevalent.. and I've tried both the old and
new version of SansDigital's TR8M's backplanes, 2 different sata PMP
HBAs (rocketraid 2722 and addonics older PCI 4 port sata pmp hba) as
well as an older addonics 3gbit sata port multiplier fan out board ..
