Could be cables - I will get a replacement to verify that. I'm less sure it is 
drives. Yes, all 4 drives were in the same machine.
Machine is a regular 2U rackmount chassis (one CPU), with proper airflow. Each 
drive has its individual aluminum fan as well. Chassis sits in a 47U cabinet, 
datacenter environment, with lots of free space around. So I'm quite sure it 
is not cooling/dust issues..
Well, unfortunately, I don't have access to hardware myself, so I can't do any 
hardware related tasks. As said, I will get those two drives shipped to me, 
and will then see myself if it is really hdd issue, or something else..
