ok, hard drives are listed in /dev as hdCX where C is a character starting at 'a' for primary master and 'b' for whatever hard drive is next and so on, and 'X' is a partition number. The mount options are stored in /etc/fstab so... pop open a root console and take a look.
Now, I can help you, but to make it idiot-proof I need more info. Specifically, I need to know how many drives you have and how your new NTFS drive is partitioned.
I'm going to assume, for now, that your Win2k isn't actually on another hard drive but on a partition on your primary hard drive and that the new NTFS drive has only one partition and is the second hard drive in your computer.
If this is the case then you need to add a line similar to the one below to /etc/fstab:
/dev/hdb1 /mnt/mp3s ntfs defaults,noatime,ro 0 0
The above line will mount your second hard drive's first partition at /mnt/mp3s (please note that you have to 'mkdir /mnt/mp3s' first or the mount will fail.) The fstab will mount the directory wherever you want it, so, if it so pleases you, you can mount it on your desktop or in your home folder. the /mnt directory is just a standard place to mount things to.
Also, please note the 'ro' in the options(fourth) section up there. That mounts the drive read-only. You can take your chances trying to write to an NTFS drive in Linux, but every time I've done it it corrupts the NTFS filesystem so...
If you need more help then please post back here with your hard-drive set up(how they're layed out) and the contents of your fstab file.
edit: Oh, yeah, and once you're done editing you need to reboot... There's probably a way to reload the mount table without rebooting but I don't know it so... reboot...(sorry but I HAVE actually had someone assume that saving the file automatically makes all the changes take effect)
edit2: And i'm a slow typer so half of what I said was already said by the time I said it...
