Hello,

I am trying to add a usb hard drive to Centos 5.3. So far I have done
the following

fdisk /dev/sdd1, added a new partition made it type 83
rebooted the system
edit /etc/fstab add the line
  /dev/sdd1                   /usb/320                    ext3
defaults        0 0

mkfs -V /dev/sdd1

then mount /usb/320

I get the following error
mount /usb/320
mount: wrong fs type, bad option, bad superblock on /dev/sdd1,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so


What am I missing?

Thanks
