As requested the results of fdisk -l

[root_at_taylor /root]# fdisk -l

This is the result of mount

[root_at_taylor /root]#mount
/dev/hdb1 on / type ext2 (rw)
/dev/hda1 on /dos type vfat (rw)

none on /proc type proc (rw)
/dev/hdc on /mnt/cdrom type iso9660 (ro) [root_at_taylor /root]#

the "Warning: invalid flag 0000 of partition <snip>" is my CD-ROM. I mount it as /dev/hdc
