During bootup a message says "No 80 conductor secondary IDE data cable installed". I have 2 HDDs and 2 DVDs in my system. 2 HDDs ( with a 8 GB and a 160 GB capacity) connected to the primary IDE through 80 conductor data cable. The DVDs through a 40 conductor datacable. Can I ignore the message or Is it ok to switch the HDD cable to DVD? Which drive requires 80 conductor data cable - HDD or DVD?
