HD in need of recovery.

My very old computer has 3 HD 2x800MB and a 1.5GB (lol).
My computer was f**ked to put it bluntly, many viruses, problems and regular crashing. I opened up "msconfig" and removed alot of stuff from starting up, when I restet my PC I got a "Illegal Windows Licence"(I don't know why, nothing illegal about my lisence) message and now all 3 HD don't work, I formated my main HD and reinstalled Windows but the other 2 HD don't show up in My Computer.

Is there any known way of recovering the 2 HD's?

*edit* I don't want to format the other 2 because I have files I need on them.

Have you checked your BIOS?

Try posting this down in the OS section of the forums.

I haven't changed the bios, I don't think it's a problem with bios.

What has it got to do with OS?

Are the drives registering in BIOS? If the drives are seen in the BIOS, and not Windows, its an OS problem. Have you reinstalled all the mobo drivers so the second IDE channel is recognized?
