i'd replace the ide cables ... with new 80 conductor cable

that'd depend on:
- the jumper settings on your disk
- the manufacturer of the disk
- the disk controller
- it is normally, supposed to find the slave disk, even if the master
is dead or non-existent

that probably means your jumpers on the disk is not right
- set the jumpers on the disk to be both cable select
or explicity set master on the disk at the end of the cable
and explicity set slave ont he disk int he middle of the cable
using master on the middle of the cable can create whackyness

maybe you have a bad disk, but is it unlikely...
and also depends on where yo bought the disk from ... mom-n-pop-me-too
stores vs an iso9001 certified outfits where they supposedly don't throw
things around or do your 6' drop tests before shipping
90% of the time .. its just bad cables and jumpers or bad mb (controllers)
