Sorry for spamming the list.
Randy, In case you are curious about what's in that NTFS superblock, here's a great reference:
If you wanted instructions for editting that superblock, this is probably the simplest way:
dd if=/dev/sda# of=block bs=512 count=1
ghexedit2 block (or what hex editor you like)
dd if=block of=/dev/sda# bs=512 count=1
You may also want to keep a copy of the original block, just in case your modified block is not happy.
The serial number is stored in the 8 bytes starting at offset 0x48.
Here's an example from one of my own NTFS Super Blocks:
adam@adam-laptop:~$ hd block
00000000 eb 52 90 4e 54 46 53 20 20 20 20 00 02 08 00 00 |.R.NTFS .....|
00000010 00 00 00 00 00 f8 00 00 3f 00 ff 00 3f 00 00 00 |........?...?...|

00000050 00 00 00 00 fa 33 c0 8e d0 bc 00 7c fb b8 c0 07 |.....3.....|....|
If you had any more questions, I'll gladly take them off list, too.

If you absolutely need to change the UUID, then you can always alter the superblock of the partition. This is a little scarry, though. The superblock is the first 512 bytes of the partition. You can edit it in the hex editor and the NTFS volume serial number should be in 0x48 to 0x4f. It's only 8 bytes long. Just alter a byte or two in that region, and you should have a new UUID.
This is NOT for the faint of heart, though.

ntfslabel /dev/sdaX LABELNAME
and in /etc/rfstab change the /dev/sdaX or UUID= part of the line to LABEL=LALBELNAME
That should do the trick. You may need to install a new package to get ntfslabel, in Ubuntu, that package is ntfsprogs.
