It is because of the 7200.11 series that I will never ever buy a Seagate again. Out of six 1.5TB 7200.11's I bought, four of them failed within a year. The remaining two are flaky in their spin-ups and spin-downs but still work overall. My experiences with these drives aren't merely anecdotal and I even flashed the firmware to the supposed fixed version before ever putting the drives to use. The firmware obviously didn't help. I don't even want to RMA these drives for fear of getting refurbed 7200.11's back.
