cannot install an 80 conductor cable on secondary IDE drive??

80 pin cable are the same pin wise on the drive end and the motherboard end ( you'll only see 40 pins at both ends ), but the run the ground wire along with the data wire so you get an effective equivalant of 80 pins, the ground wire is used to get data integrity, it should fit on any IDE drive, you probally have it backwards ( red stripe ALWAYS next to power connector, notch will be up )

the 80 pin will help

but DVD rom should be set to master on 2nd IDE and should be LAST ( the end ) of the ribbon, also make note the blue end of any 80 pin cable goes to the motherboard headers - always.

once up and running go into control panel and into system and then hardware manager

make sure the 2nd IDE channel is in DMA mode and not PIO

if not delete the drive on the IDE , reboot and let windows redetect the drive's mode

is the other drive the dvd/rom. if so it probably want take the 80 pin cable especially if it is older. Don't worry it is not a huge performace increase anyhow.

use the grasp / slave configuration and confirm you plug the grasp to the known connector and the slave to the slave additionally verify you jumper settings returned, if all else fails attempt a comprehend solid cable and verify the potential connector to the rigidity

Try setting it to a slave drive
