Hi,

There are several avenues that you might pursue. If this were my unit, I would do the following things first:

Clear the CMOS and when you start it back up, then set the BIOS at default.

Check all cables and make sure that cables and jumpers match what is required. What bothers me about this is that you said it worked and then quit. However, I am including this because you said you had tried other combinations of drive, so just check to be safe:

The master and slave jumpers must be set up correctly on your drives as displayed on the top of each drive.

DO NOT mix master and slave with CS (cable select) on the same ribbon cable. If one is Master the other MUST be slave. If one is Cable Select the other one on the same ribbon cable must be Cable Select. (Please note that the majority of hard drives are factory default as Cable Select)

Make sure the drive is placed correctly on the ribbon cable as shown below:

M
O
T
H ==Ribbon Cable=== Slave ===Master (end of cable)
E
R ..................................„» OR „º
B
O == Ribbon Cable==Cable Select==Cable Select (end of cable)
A ..............................( as Slave)……. ( as Master)
R
D

Ribbon Cables and colors of 80 pin cables look and are to be used like this:

Motherboard============Slave==============Master
……….…..Blue…………..….……..Gray…......…….………………Black
.
Make sure a master is always present, because you can not run a slave without a master.

Cables must be the 80 conductor cables and never any more than 18” long.

A friend recently told me that with Western Digital if it is the only drive on the cable, the jumper will need to be removed ( try removing the jumper and connect the drive by itself on the IDE channel ) I don’t have Western Digital so I can’t verify this, but might be worth a try

Please note thatt the floppy cable red mark is put on opposite as the regular hard drivers. Otherwise, the red mark faces away from you as you work in the case or you could say it faces the power source for the drive.

Please let us know if you have other questions or need more assistance.
