Code:
/dev/cdrom /media/cd iso9660 ro,user,noauto,unhide 0 0
The fstab above works for me, although you can also go simpler; for my usb drives I just have:
Code:
/dev/sda1 /media/usb vfat rw,user 0 0
The other thing to be aware is how you try to mount. As a user, you should only use the path of the mount point:
NOT
Code:
$ mount /dev/sda1 /media/usb
If you're still having problems, post your fstab. And one last thought. You say you can't mount /hdb1, so I assume that /hdb1 is a directory and you're trying to mount /dev/hdb1 to it. If that's not the case, then that's the problem.
