Unable to see slave drive

Hi
It is a Win2K system. The primary drive (C) is formatted FAT32 and the secondary drive (G) is formatted NTFS. The secondary drive is completely accessible when installed on the Win2K machine. However if I slave it onto a different pc running WinXP pro with its primary drive also NTFS I cannot see the above mentioned secondary drive. I have also tried putting this drive into an external usb caddy with exactly the same result. I have tried installing a temporary replacement C drive, formatted NTFS and installed WINXP pro on it in the original system. Still cannot see the slave drive.
Why oh why?
