Overall, I'd rate the HD in the Lacie (Seagate) five stars. The Lacie diagnosis of the problem and Lacie's internal controller board 1 star.Bought a d2 Quadra 500GB early in 2008. It worked well for two years. Then the problems.The drive continued to operate as if it were powering up, but would not mount. Lacie diagnosed it as a power supply problem.Eventually went through three power supplies with no luck. I thought the drive and my data was dead. That was until I bought this...Thermaltake BlacX Duet eSATA USB Dual Hard Drives Docking Station ST0014U here at Amazon.I popped the drive out of the Lacie and dropped it into this docking station, and volia! The drive worked again. And has been rolling along for another two years already.Seems it was not a power supply problem. It was an internal Lacie controller that failed.
