AFAIK there's no mechanism to retrive these values from a ATA drive.

It depends on the hard drive. Some of them have a limited number of sart/stop
count and using standby mode can significantly shorten their life.
Others are designed for typical desktop applications; for these it's
leaving them spun up 24x7 which can be harmfull.
SMART can usually give details about this.

On my laptop I use 5s for idle and 10s for standby.
