Hard Drive Troubles?? Experts wanted!

The story;
Was running 20G with 98, and 60G with XP, dualbooting.
Wanted to just do XP but 60G wouldn't boot(error - can't load OS)
so installed XP on 20G and all is well. Can see both drives, works well.
I installed Diskeeper to try out, but found it slowed down machine too much(p3-533). So I unistalled diskeeper and checked to see what the XP defrag showed. It wouldn't launch, must have got buggered when Diskeeper uninstalled. I thought that I would do a recovery from the XP disk to fix. Now the trbl gets bad!!
Computer won't start, says disk read error. Tried using recovery from XP and did a fixmbr, no help. Tried reinstall of XP no help.
Tried reinstall on 60G, set to master in bios, still error of can't load Operating System. I can't get the computer to start no matter what I tried.
I have a real old 1G hard drive with 95 on it. Mounted in computer set as master(it's default) set other HD to slave and presto the computer boots. I can see the 20G or the 60G, depending on which is hooked up.
How can I fix the HD's so they boot. Partition magic shows the 60G with an error 110, and says needs to be formatted, XP says okay. How do I format it?
The 20 G shows healthy with both. Ideas??

 

I would suggest go to the manufacturers site and download a low-level format program, run it and then do an fdisk and regular format. Should work fine.
