I have a 320Gb external hard drive that has both usb and firewire. When i try and fdisk -l using the firewire connection i get this result.

Disk /dev/sdc: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

Disk /dev/sdc doesn't contain a valid partition table
adam@ubuntu-gnome-x64:~$ 

and can't use the drive, however when I use usb I get this result

Disk /dev/sdc: 320.1 GB, 320072932864 bytes
255 heads, 63 sectors/track, 38913 cylinders, total 625142447 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000d860d

Device Boot      Start         End      Blocks   Id  System
/dev/sdc1            2048   625141759   312569856   83  Linux

and the drive is fully usable. I would prefer to use the firewire connection as I boot Ubuntu from an external usb drive and this would free a usb port.
