I bought a WD My Book Studio Edition II 6TB, with the intention to use it as a RAID 1 eSata drive on a Windows 7 (64bit) machine. So far, it gives me the following problems:
(1) The drive disconnects itself for no reason after a few hours. I have to unplug the eSata cable and plug it back again for the drive letter to appear again.
(2) On eSata connection, the WD Drive Manager does not start. If I go to Program Files to start WD RIAD Manager, the drive canot be detected.
(3) On eSata connection, the WD software “Data Lifeguard Diagnostic for Windows” reports My Book Studio Edition II 6TB as FAIL. It reports other two Seagate drives as PASS.
(4) On eSata connection, the WD software “Data Lifeguard Diagnostic for Windows” cannot access SMART disk information for My Book Studio Edition II 6TB, although it works fine with other two Seagate drives.
(5) On reboot and eSata connection, my computer BIOS reports My Book Studio Edition II 6TB as “Damaged”.
I bought this from Scorpion Technology. They said that I can return the drive but need to pay a minimum of 15% restocking fee. After reading a lot of news groups, I have the firm conclusion that WD or Western Digital is a name to be avoided in the future.
