I swapped my ribbon cables on my 2 hard drives for rounded cables to improve air flow and also in hope of fixing an annoying problem-my system only sees 1 hard drive all the time,and the other sometimes,like after a hard boot or sometimes after a reboot;cables seem tight,2nd drive only stays visible for a short time after it reappears. Win XP on both disks,both are W/D drives ,primary is 80 gig,secondary is 30 gig TIA, Dan "Natural ability without education has more often attained to glory and virtue than education without natural ability."
