In responce to jasonwichman's later Jul 3 post, you have made some assumptions which are incorrect.
Win98 cannot read NTFS partitions. The Microsoft knowledge base, and XP system help files will confirm this for you.
P2P networking does not rely on filesystem compatibility for two different OSs to share files - that service is provided by the middleware. For eg Win98 can share files with Linux and Mac file systems on a network, and vice versa. This is seperate and unrelated from the ability to read a local hard drive partition.
Furthermore if you were able to read a local NTFS partition from Win98 then NTFS security would be compromised as Win98 is not a multi-user OS and has no concept of file permissions (additional 3rd-party software or Linux will permit access though still requires the password for any restricted access files)
