mounting error USB stick

[Paul Cartwright <ale@pcartwright.com>]

Now I am getting an error when I stick in my USB stick and check the box for 
mounting it. The error message says:
Mount: wrong fs type, bad option, bad superblock on /dev/sdf, missing codepage 
or helper program, or in some cases useful info is found in syslog - try 
dmesg | tail


here is dmesg | tail:
sdf: assuming drive cache: write through
SCSI device sdf: 512000 512-byte hdwr sectors (262 MB)
sdf: Write Protect is off
sdf: Mode Sense: 00 00 00 00
sdf: assuming drive cache: write through
 sdf: unknown partition table
sd 11:0:0:0: Attached scsi removable disk sdf
sd 11:0:0:0: Attached scsi generic sg6 type 0
usb-storage: device scan complete
FAT: Unrecognized mount option "flush" or missing value


when I do a mount:
~# mount -t vfat /dev/sdf /media/sdf1

paulandcilla:~# mount 
/dev/sdf on /media/sdf1 type vfat (rw)

it shows up. So how do I fix the automount error?
here is /etc/mtab:
/dev/sdf /media/sdf1 vfat rw 0 0
