看了下hdparm的man,-y 和 -Y 有什麽差別,看不太懂。好像加到rc.shutdown都可以達到同樣的效果。
- -y Force an IDE drive to immediately enter the low power consump-
- tion standby mode, usually causing it to spin down. The current
- power mode status can be checked using the -C flag.
- -Y Force an IDE drive to immediately enter the lowest power con-
- sumption sleep mode, causing it to shut down completely. A hard
- or soft reset is required before the drive can be accessed again
- (the Linux IDE driver will automatically handle issuing a reset
- if/when needed). The current power mode status can be checked
- using the -C flag.
