I'm attempting to mount my WinXP NTFS fs for access with Fedora Core 3. I've seen a couple of sites, and one tells me to run "cat /proc/filesystems" and if I see "ntfs", then FC is able to understand ntfs and I can continue. Well, I didn't see it. Does this mean that I'm fairly stuffed for accessing my ntfs partition without recompiling the kernel? Little help??

Yes, it does. You will need to recompile your kernel with NTFS support enabled. Note that writing to NTFS partitions in Linux is rather sketchy and can cause severe damage to the files on the drive.

Actually, no.

Just install the appropriate kernel module, and things will work fine (reading, not writing, however).
