I have a intel al440lx board with a main drive western digital 6.4gb, an atapi cd-rom, a lite-on 40125s burner and the second hard drive is a 480mb seagate and no matter what setup I use (master slave cable select) mix and match it won't detect the hard drive, plus it won't detect the other hardware on the same cable as it is until I unplug the cable from the hard drive (seagate)is there any different way to set it up? any help,tips etc. would be very much appreciated.
Thanx :-)

Try to install the small HD slave to the large one. Do not use cable select: it is master or slave.Install the burner and CD-ROM on the same port, one master and the other slave.The bios should auto-detect the new hard drive. If not, the hard drive controller on the HD is probably at fault. You could check the drive in another PC just to make sure.

Try detecting the hard drive alone or in
another machine.

Some of the earlier drives were incompatible
with other brands.

Ditto, what tech-fred said . . .

I've had some old drives in the past, that absolutely REFUSED to work with anything, other than a CD/Rom drive.

But Petit-Jean, I've also had some old quantums that would *ONLY* work together as master/slave if cable select was enabled on the master, and no jumper at all on the slave. Some of those really old drives could be doozies to work with, the moment that another drive came into play.

Hey Intel, AMD rulez!

I am guessing here. What may be the problem is that the LBA 6.4 drive will not work with a small non LBA drive. Go into the bios and manually put the parameters of the small slave drive in #47 and disable LBA for that drive. That is to say do not auto detect it.
