I ran the command:
atacontrol spindown ad10 60
on my desktop and similar one on my laptop.

In the morning I found that laptop rebooted overnight, and desktop was still functional, but I suddenly got flooded with the message:
fwohci0: device physically ejected?
then the system froze and had to be rebooted. I never use anything related to fwohci.

Harddrives are:
ad10: 190782MB <Maxtor 6L200M0 BACE1GA0> at ata5-master UDMA100 SATA 1.5Gb/s
ad4: 152627MB <WDC WD1600BEVT-22ZCT0 11.01A11> at ata2-master UDMA100 SATA 1.5Gb/s
