I would like to know the process necessary to re-assign the drive letters on my computer.  I have added an additional hard drive, and I really want it to be D: not F:.  The original system was configured with one hard drive (C: - of course), CD rom drive (D, and a DVD (E.  I am using XP as an operating system.  The task seemed simple; however all I have encountered is frustration.  Imagine that, a Microsoft product that is difficult to work with.  If someone can suggest where to start, or the correct area to be modifying, I would greatly appreciate it.
Thank-you for at least reading my plea,
Condor

If you go to Control Panel/Administrative tools/Computer Management/Storage/Disk management and right click on your hard drive F: one of the choices in the context menu is "change drive letter and paths".

Changing a drive letter can be a complicated process since all the paths to everything on F: will have to be changed to D: and everything pointing to the CDROM will be changed to F:

Good luck

   The other option is to change which cables your drives are hooked up to so that the second harddrive becomes D.  I would think that if you unhooked the CD drive and put the second harddrive on that connector that the second harddrive would become D.  Of course, this requires you to open the case of your computer and it does not always work out that simply (not recommended for the faint of heart or clutz), but that is how I have changed drive letters in the past.

Many thanks for your exceptional assistance DLWolfF0; it was right on the money!  I just could not see the forest from the trees.  Also, thank-you on the heads-up on the programs referencing the old drive lettering.  I was aware of it, and can handle their re-mapping.  I am quite impressed with your incredibly quick responsetime, keep up the great work.  Note: Ray, I was looking at swapping the cables, however I do now have a Master and Slave on both Primary and Secondary cables, and getting them all swapped around was not going to be as easy.  Thank-you for the information and assistance.
I am in your debt,
Condor.
