Tommyhat,
1.If your drive is an IDE hard drive, first check the jummper settings on the back of the HD. If you are using 80 pin cables, most times CS (cable select) should be the jumper setting. Unfortunately, master doesn't alway work with 80 pin cables.
2.If your computer does not recognize the HD, try to make it a slave to another drive on a separate computer(computer #2)but make sure there is plenty of space on #2s computer incase you need to copy data.
3.If computer #2 recognizes it as a drive under mycomputer, right click and click explore. Select all data and copy it into a folder on computer#2.
4.If this is possible, your hard drive has bad clusters or sectors, and not necessarily "cooked".
5. If computer #2 does not recognize it as a drive under mycomputer, right click the mycomputer icon and click manage. Select disk management if the drive is there, but says unallocated...it's lights out for your HD data.
5. If none of this is possible, and your hard drive cannot be seen by your computer, computer#2, chances are your hard drive is damaged.
Remember you can run diagnostic tests without having to go into windows, just boot off of your floppy. Find a computer where you can access the internet and download free diagnostic tests from what ever company made your hard drive.You can also try to ghost your drive the same way, but of course you need a ghost floppy as well.
Good luck.
