Still Unable to mount /media/zip as regular user

Thanks Alexander for your reply. I went through the man pages with all the option the last one I've tried:
/dev/hdb4               /media/zip              auto    user,exec,dev,suid 0 0
 but I still get:
[ed@mybox~]$ mount /media/zip
mount: special device /dev/hdb4 does not exist
 even thoough /dev/hdb4 is there. I need to be root to mount the device:
[root@mybox ~]# mount -t vfat /dev/hdb4 /media/zip/
Then it get's mounted. Why I can mount the cdrom but no the zip drive? These are they descriptions on /dev:
[root@mybox ed]# stat /dev/hdb4

Do I need to tweak somehow the block devices? Has anyone gone through the same issue? Thanks a lot!
