I have no data but I don't think the drive isn't killing itself. I have one in a Windows box and I'm not seeing this problem. My suspicion is that Linux is doing something that wakes the drive up once every two minutes and then lets the drive go back to sleep. That amounts to 30 load cycles an hour which hits the 300K spec in 13-14 months. I don't know that the drive will die when it gets to 300K. All I know is that's the spec WD gives, not only for these Green-series drives, but also for their Blue, Black and RAID Edition drives. The thing is I have RAID Edition drives in similar systems and they aren't racking up this count value so they presumably will last longer. I have NO data as to why this is happening. It just is. I figure I've got 6 months to find a solution, and then without a solution 6 more months to swap the drives out if I get too worried. - Mark
