mount complains about file system type

Hi All,

I have a usb external hard drive hosting debian testing (listed as sdc and sdc1) and am trying to mount it. Its ext4 and this is the command I use with the resulting error:

root@polaris:~# mount /dev/sdc -t ext4 /mnt/external-drive
mount: wrong fs type, bad option, bad superblock on /dev/sdc,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

BTW- tail syslog shows this:

Nov 3 17:32:09 polaris dbus[2830]: [system] Successfully activated service 'org.debian.apt'

Help appreciated,
