FC5 doesn't have native ntfs support. So do what I tell you and It should work. Cause if you create another FAT32 Partition as a workaround you'll suddenly figure out that the max. filesize is 2GB.
1st create a directory within mnt using mkdir
mkdir /mnt/win (for example)
2nd check your kernel version with
uname -rm
3rd go on this
Link
and download the RPM matching to your kernel version
4rd issue the command as ROOT with "su -" it includes the PATH Variables...
fdisk -l (l like language)
It will show you the partitions with NTFS Filesystems
after you've done the steps 1-4
5th Install the rpm with (below it's just an example for my kernel)
rpm -ivh kernel-module-ntfs-2.6.17-1.2174_FC5-2.1.27-0.rr.10.5.i586.rpm
6. mount the partition in your Linux tree
mount -t ntfs /dev/sda3 /mnt/win
(You'll need to asign probably another device then sda3 depends on the output of fdisk -l )
7. check with
mount (enter)
if it was mounted correct
8. If you want include it to your /etc/fstab so that you don't have to do the step 6 everytime.
