Getting my external disk back.

Asked by Chris Els on 2012-11-20

I have a Samsung 320GB external USB hard disk, which was previously formatted with FAT32 format.
I want to backup data on my internal hard disk to this disk, and install Ubuntu 12.04 LTS on the internal HD.
I tried to install to the external disk first, but something went wrong, and the external HD is no longer accessable from
the computer. When I do lsusb; sudo fdisk -l, I get the following output:

How do I get the external HD back, and get it formatted so I can make backups to it please?
I currently have Ubuntu 10.10 on a Mecer Solo Notebook.

TIA,
Chri

Hi ,

if disk has nothing inside then format it to NTFS. Why FAT32 ? FAT32 is for USb-flash . 320GB with FAT32 is waste of time.
FAT32 is so deprecated filesystem.

Try to use Gparted or Disk Utility to format again the drive.

Thanks
