Ext3 Fedora Core 5 fstab problems

# Pluggable devices are handled by uDev, they are not in fstab

/dev/cdrom /media/cdrom iso9660,udf noauto,users,exec,ro 0 0

i get this error:

mount: wrong fs type, bad option, bad superblock on /dev/sda5,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

for /dev/sda5 which is my fc5 partition

without umask it works, but without write permissions for all users, which is my goal -- i have a shared workspace for Eclipse in my home folder on my fc5 partition. ext2fs drivers auto mount that drive under windows so eclipse can get to it.

thanks in advance
