Create Drive Letter in XP for Boot Disk of Old PC

I've moved the primary master (cable select) boot disk from an old computer with a dead motherboard to a new computer and would like to use it as a secondary hard drive and retain the data currently on it. I had hooked it up to one computer (as the cable select -> slave drive) and it was automatically named as the D: drive and worked fine, but now I've installed in the new computer I want it in and XP won't let it show me. When I try to populate the drive, it gives me a letter C: drive, but that's the primary master drive so it does nothing. When I enter Disk Management, I cannot change its drive letter because it's greyed out. How can I make this drive not a boot drive and accessible without reformatting it?  THANKS!!

You can assign what ever drive letter you want using the diskpart utility;
You can use the diskpart utility within both Boot CD (Windows XP) or within the OS.

Within boot CD you need to enter the recovery console and type 'diskpart' and press 'Enter' to initialize the diskpart utility.

If you do this within the OS; go to the following link to guide you though step by step manner to assign any drive letter you with to any drive;

Checkout the 'assign' command...

Good luck

OK, I need more luck... I tried diskpart and found that the partition I want to assign a drive letter doesn't have a volume that I can focus on to assign a drive letter. Plus,  I cannot create one using the "create volume simple" parameters (would this be data-destructive if it did work??). HELP??
If you would mount a volume; no, its not...
Im looking for a great step by step guide I resently saw... In the meantime, I would go in the recover partition way because missing volume may suggest corrupted MBR...

FINALLY!! The culprit for all of my problems was the old hard drive's GoBack software that had changed the NTFS partition type from 07 to 44. I downloaded DFSee and was easily able to change the partition type back to 07. XP now recognizes it!!
