Roman, I have just gone through MEGA headaches with this same thing on these same drives. I tried everything that anyone suggested to solve the problem. I had always discounted the suggestion that they were running too hot because I thought I had sufficient ventilation. NOT SO!! When I moved the drives to the upper 5.25 bays and put a Zerus twin turbo exhaust fan, which happens to fit in a 5.25 bay, and positioned another fan in the rear of the case blowing directly at the drives. Problem solved ;-) I can not stress enough that Seagate drives need adequate cooling.
