I have no data but I don't think the drive isn't killing itself. I |
20 |
have one in a Windows box and I'm not seeing this problem. My |
21 |
suspicion is that Linux is doing something that wakes the drive up |
22 |
once every two minutes and then lets the drive go back to sleep. That |
23 |
amounts to 30 load cycles an hour which hits the 300K spec in 13-14 |
24 |
months. I don't know that the drive will die when it gets to 300K. All |
25 |
I know is that's the spec WD gives, not only for these Green-series |
26 |
drives, but also for their Blue, Black and RAID Edition drives. The |
27 |
thing is I have RAID Edition drives in similar systems and they aren't |
28 |
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 |
31 |
got 6 months to find a solution, and then without a solution 6 more |
32 |
months to swap the drives out if I get too worried. |
