I have a Biostar M7VKD KT133 Mobo. On my primary IDE cable I have a Western Digital HDD, ATA66 (Master), and a BTC 24X CD-ROM, ATA33 (slave). On the secondary cable I have an LG DVD/CD-re-writer combo drive (master). I want to ditch the BTC CD-Rom, as it drags my ATA66 HDD down to ATA33. If I unplug the cd-rom my system fails to boot, with the message 'primary HDD failure' It also Fails to auto detect the hard drive/lg drive. if I turn the PC off, plug the BTC cd-rom back in it boots up fine. I have tried the diagnostic floppy supplied with the HDD. It reports 'no fault found'. I have tried another cable. no effect. Any Suggestions?
Got the info needed from your link Eric10. non of the other searches I had tried came up with a 'neutral' posistion for the jumper. they all suggested the cable select option, but as my mobo dont support cable select is didn't work. now have a nice fast HDD back. defrag take under 10min's, not 45......
