I've just checked out the man page for hdparm. There I noticed the |
2 |
new -J switch. It reads: |
3 |
|
4 |
> Get/set the Western Digital (WD) Green Drive's "idle3" timeout |
5 |
> value. This timeout controls how often the drive parks its heads and |
6 |
> enters a low power consumption state. The factory default is eight |
7 |
> (8) seconds, which is a very poor choice for use with Linux. Leaving |
8 |
> it at the default will result in hundreds of thousands of head |
9 |
> load/unload cycles in a very short period of time. The drive |
10 |
> mechanism is only rated for 300,000 to 1,000,000 cycles, so leaving |
11 |
> it at the default could result in premature failure, not to mention |
12 |
> the performance impact of the drive often having to wake-up before |
13 |
> doing routine I/O. |

I've never heard of this. Are other Caviar Green users aware of this? |

Anyone having any experience with this? |
