External HDD

I've bought a nice External HDD case from iSTAR and the 1TB drive that I purchased arrived first. Keen to get some files onto it I just had to plug it in.

Once it was formatted up via the WEB interface I telneted back in to see what it looks like

# fdisk -l /dev/hda
Disk /dev/hda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1               1          32      257008+  83  Linux
/dev/hda2              33          95      506047+  82  Linux swap
/dev/hda3              96      121601   975996945   83  Linux

Mount the drive in a real Linux machine allows to see some other interesting things about the format of the partitions.
