W2K Pro drive letters reassigned...

Here's a strange....

I have a lot of drives on my system, and they used to be:

A floppy
C Local (FAT 32 partition of D)
D Local main NTFS
E CDR
F DVDR
G Removable disk (when digital camera is plugged in)
H Local NTFS

Two nights ago all was well. I performed a Norton Ghost by removing H (it is in a slide tray) and installing another C/D drive for copy. I Ghosted DISK 1 C/D to DISK 2 C/D. All went well. The next morning I remove the Ghosted drive and reinserted the H. Now my drive desinations have changed. I didn't notice it at first...

Now I have:

A floppy
D main
E CDR
F DVDR
G Removable (WHICH WAS C!!!)
H Local NTFS

Now, when I plug my digital camera in, it becomes

C Removable.

Everything is intact, I just have all my drive designations scrambled. Not sure what if any problems might crop up with C being changed to G.

I must admit it is all confusing to me. Not sure what happened. Need I be concerned and is there a suggestion for changing them around?

Thanks,
