Is there any way to avoid specific HDDs from spinning up at boot time?
There are 3 HDDs in my HTPC (Ubuntu 12.10) and 1 SSD (boot drive). I don't want the HDDs to spin up when booting to reduce boot time, save energy and expand the HDD's lifespan. However, I think the onboard HDD controller needs to know which drives are there at boot time to make them available later for the system. Is there any possibility to avoid the spin-up?
Mainboard: ASrock A75M-ITX (UEFI)
APU: AMD A8-3870K
HDDs: WD20EARS, HD204UI, WD20EARX
SSD: OCZ Vertex3 60GB
(4GB DDR3-1600, TV-Tuner, Sharkoon 400W PSU)
Do the HDDs spin up instantly when they receive power from the PSU or to they spin up when they receive some data?
