XP not recognizing old hard drive

Hi'ya everyone. I figure its better to give a little background on this in case the cause is something I have not thought of.

My pc was running with 2 hard drives. The C: was an old 15 gb and the D: a larger 120 gb. The c: only had XP and drivers and the D: had all my files, apps, and extras.

One day, the pc locked. I could get no response from anything. I hardbooted and it came through the bios, then stopped when it tried to access the hard drive to load the OS. I tried to repair from the XP disk, but could not even "dir" from the c prompt. I figured the C: drive was dead.

Bought a new one. Went from 15 gb to 160 gb. My old motherboard (3 years) could not handle that much, so it wanted to be partitioned in two. I loaded XP and found my old drive was not recognized. The bios does see it, just not XP.

I have checked the jumpers, unplugged and replugged the IDE cables, and wiped the second new partition (so the old drive would definately be the D: drive).

I then went start - control panel - administrative tools - computer management. Then I clicked on disk management and looked in the right hand pane. Its not there. I only see the c: drive and the unpartitian space. No D: drive.

The two physical hard drives are made by different companies, so they are easy to spot in lists. I am just not finding my slave hard drive in XP at all.

Could someone please recomend something? I'm at my wit's end.

In disk management down at the bottom where it gives you a graphical representation of your drives, is there a drive listed without a drive letter?

I am at work right now, but I will check when I get home. Thank you.

Oh, wait. I just re-read that. The only things I see there are the c: drive, the half of the c: drive I did not partition, and the dvd (e:) drive.

The old d: drive (the maxtor drive) is not appearing there. It continues to appear in the bios, however.
