USB flash drive fail to automount in Debian

When I plugin the usb flash drive, it pop up the message like below:

Error mounting: mount exited with exit code 1: helper failed with:

mount: wrong fs type, bad option, bad superblock on /dev/sdf1,

       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try

       dmesg | tail  or so

Then I check out dmesg | tail

[x.x] sd 9:0:0:0: [sdf] Assuming drive cache: write through

[x.x]  sdf: sdf1

after googling I found
http://crunchbanglinux.org/forums/topic/7681/solved-statler-failed-to-mount-media/

and
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=597223

the debian-installer put the following into /etc/fstab
/dev/sdf1       /media/cdrom0   udf,iso9660 user,noauto     0       0

Just delete it...Orz
