Initially i never had this problem but somewhere along the line i got the dreaded Jraid pausing problem. (cue thunder) Of course i googled, updated drivers/bios, checked HD fitness et etc etc. I even changed OS ( XP to vista) and still the problem existed.
The driver for device \Device\Scsi\JRAID1 detected a port timeout due to prolonged inactivity. All associated busses were reset in an effort to clear the condition.
Only have ICH so cannot do that. Breaking the raid and putting them all on intel sata ports untill i get a new motherboard and its not going to have a JRAID controller on it. I emailed gigabyte but have my eye on a new P35/45 board.
