I suspect the problem is becuase you have Win 2000 installed on your second drive. Windoze always wants to boot from the first drive, even if installed on another drive, so it writes boot information to the first drive. If you put grub on the drive, that may have overwritten the Windoze boot information on the first drive (in which case, you would not be able to boot into Windoze at all).
You can use grub to map your drives so that Windoze will believe it is running from the first drive. Try modifying your Windoze 2000 entry along these lines:
Code:
title Windows 2000
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd0,0)
root (hd1,0)
makeactive
chainloader +1
You can also go the opposite route, and use NTLDR to dual-boot Linux and Windoze 2000; one set of instructions (using LILO) are at

Hope this helps.
