Before you went to bed
we were at the point where you recovered the partition table of the drive and had the whole of it as unallocated space.
From that point, use Gparted to create your partition(s) with the ext3 filesystem.
Right click on the drive and select "New" and select ext3 as the filesystem.
If you just need one partition, use all the available space.
If you need more than one, adjust them according to your needs.
The first partition will be a primary one.
Next one will be an extended one containing one or more logical partitions.
When you're done, click "Apply" and Gparted will create them and format them with the selected filesystem.
No need for an extra format as I wrote in my previous post.
