Adding external HDD to Raspberry Pi

[Gabor Szabo]

So finally I install the Raspberry Pi I bought a few weeks ago and wanted
to add an external HDD.
I plugged in the external hard drive and /var/log/syslog printed the
following:


Dec 14 17:02:55 pi kernel: [  759.981949] usb 1-1.3: new high-speed USB

But then when I try to run


$ sudo fdisk /dev/sda

I get

fdisk: unable to open /dev/sda: No such device or address

$ ls -l /dev/sda

brw-rw---T 1 root floppy 8, 0 Dec 14 17:21 /dev/sda

$ sudo fdisk -l

only lists the sdcard


The external disk is brand new and it has NTFS on it. I have not handled
disk in linux for a long time, but a I recall I am supposed to use fdisk to
partition it and then use mkfs.ext4 to format.


So what am I missing here?
