I'm the author of ataidle.  I know it is a hack, and I agree that
power management should be done at the driver level.  However, I have
released what worked for me in the hope that other people find it useful
- but yes, there is always the possibility that data will be lost, since
  it does bypass the driver.

Unfortunately I've been very busy recently and so have until
now been unable to look at FreeBSD 6.0 and the new ATA driver.  
I have however updated ataidle to cope with the 
new API and it can be downloaded from .
