NOTE: Ultra Advanced Technology Attachment (ATA)/66 hard-disk drives require an 80-conductor cable to transfer data at
full speed. The 80-conductor cable has a 40-pin connector just like the Ultra ATA/33 cable but has twice as many wires
within the cable itself. If you use an Ultra ATA/33 cable with Ultra ATA/66 hard-disk drives, they will transfer data at Ultra
ATA/33 speeds.
