Harddrive Problems

[ProgrammingFun]

I recently downgraded my Windows 7 computer to Windows XP (for my dad) but have faced many problems.
First of all, I had 4 partitions on Windows 7:

two physical harddrives:

HDD 1 = 1 partition (Operating System)
HDD 2 = 3 partitions

I formatted and installed XP on HDD 1 but now my computer won't recognize the other 3 partitions.
It only shows me C and D and when I click on D, it says to format it before using.

I really need the data on those three partitions, so...any suggestions?

Thanks

At first I thought that win 7 was NTFS and Xp wasn't but then I remembered there wasn't two versions so it must have been NTFS.

This might help you

Thanks but it turned out that my XP was corrupted so I reinstalled and voila, I could see my harddrives!

I have 2 hard drives on my computer, a 2 Gig, that has Windows installed on it (C and a 10 Gig, for files and stuff (D. They are two totally separate drives, not partitions.
Anyway, one day I booted up the computer and Windows wouldn't recognize the D: drive. The BIOS read it fine. I concluded that my hard drive crashed. Is there any way I can recover the data? I have tried to access the D: drive in DOS, but It doesn't want to read it for some unknown reason.
Please help me out from this problem....
Thanks in Advance

2 and 10G hard-drives? Are you running a flashdrive as your HDD?

LOL, she probably is.

But anyway, you could try re-installing your operating system (it could be an OS problem like the one I had)
or you could check your hardware to see if the drive is properly plugged in (although this shouldn't be the problem).
