I will split the drive into 20G and 60G partition

Will format it in NTFS

Why do you feel the need to split it into two partitions?

Dban is used it wipe hdds clean, there are others, as long as the wiping of data is 7 or more times for a really good clean, then no data is capable of being recovered, usually they come as standard, like DoD settings and yes that Department of Defense which is 7 times the program overwrites the data.
in comparison to Dban evidence eliminator is rubbish.

Uses several advanced shredding algorithms (Dod 5220-22.M, US Army, Peter Guttman) to securely wipe data.

forgot to mention diskwipe is freeware
