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
