Before declaring your HD "deceased" try playing around with the jumpers located at the back of the hd. Try the "Master" position instead of the "CS" or Cable Select which is usually standard when pcs ship from the assembly plant. A diagram of the various driver positions is usually printed on the hard disk.
With different jumpers position selected, try entering the Bios and checking if said Bios is detecting the disk.
If all else fails, go to you hd manufacturer's web site and get their hd diagnostic s/w. It is most often free and it fits on a floppy. It scan the particular hd and gives you a diagnostic. If the disk is at fault, this s/w will tell you. If the s/w tell you the disk is OK, then you know it's your IDE setup that is wrong. Verify tha you selected the correct IDE connectors and that they are oriented properly.
With all this, you should be fine, if not, feel free to post further questions.
Good Luck,
Simon
