Strange things with my hard drive

[Victor Tsaran]

Hell, listers!
I know some of you, especially Kerry, are big hardware specialists. Hope you
will be able to advise something for me this time as well.
I am putting together a new machine. Whenever I connect the hard drive to
the IDE0 and CDROM to IDE1, both on master, I get "hard disk failed...", but
CDROM is found. However, if I connect hard drive to IDE1 and CDROM to IDE0,
both to master, then both are recognized fine. Why is this hapenning? I
tried these combinations several times, and the same result comes out.
Can you suggest something?
Victor
