Mounting troubles

[Damon Siefert]

At the bottom is a copy of my partition table (generated with FDISK.) hda1 is my Windows partition, hda2 is /, and hda3 is the extended partition (not sure why it's labeled Win95) that contains the rest of my linux partitions. The problem is that I want to mount hda4 as a shared data partition. MOUNT says "wrong fs type, bad option, bad superblock on /dev/hda4, or too many mounted file systems." I don't understand this - the file system is fine as win98 mounts it with no problems. If you can think of anything I can do to make this work, PLEASE let me know.

Thanks,
Damon Siefert
