Writing to NTFS in Linux is still experimental. I actually had Mandrake 7.something working where it could write to NTFS, but to do that I had to specially compile the kernel for it. Since it _is_ experimental you can potentially hose your NTFS system by writing to it,
so I haven't really done that since that one experiment. However, there is potentially another way...
You didn't say what fs your Linux system is using, but if it is using ext 2 or ext3 you can access it from XP. There is a program that I have been using for quite some time, made by John Newbigin, called explore2fs (
http://uranus.it.swin.edu.au/~jn/linux/) that allows access to ext2 and ext3 from WinXP. Although it can write to the Linux partitions, the software author stresses that that capability is still a work in progress and is dangerous.
It won't, however, read ReiserFS. I have used it to copy files from Linux to XP (and before that win2000 and evern WinNT 4) and found it to be quite handy. So you might want to try it out and see if it makes the problem of moving files from Linux to XP easier. (If you are using ReiserFS, you could make a partition on your hard drive that is formatted as ext2 or ext3 to use as your transfer area. Just make it a bit bigger than any file group you would expect to transfer.) Sorry for the
