Looks like it. The thing is I rarely use BOTH the 3 TB Green and the 1.5 TB FreeAgent GoFlex drives. I was actually retesting both of them recently, and they passed the tests... and then a few days later, they died. The 3 TB Green was working but like the RE4-GP, it wouldn't read certain files. Quite a lot of them actually. As for the 1.5 TB FreeAgent GoFlex drive - it was a catastrophic failure. The drive wouldn't start and I can hear very loud clicks. Sounds like a read/write head skipping on the platter...
