Use disk vendor tools!

If you are an individual worried about other individuals 
reading your data then vendor tools are more than enough.

Each vendor has their own download tool set to partition, format and
check the drive for errors. Look for (demand) tools you can burn
to a stand alone CDROM.... (think .iso file).

These tools are most valueable when repurposing hardware inside
an organization.

Speaking of Burn.... the only way to 100% wipe a magnetic drive 
is to take the media up to and beyond the Curie point -- i.e. 
blow torch to cut it in half...  turn it to slag.


If you are an "agency" then you should not be getting info from this list
so go away or call me for an expensive consultation gig.   Governments
will go to astounding lengths to extract data each group has policy and
procedures to match the needs.

If you are a company (federal contract, human resources personal data,
credit card data or pharmaceutical company for example) then each drive
and the data set needs to be tracked and audited from beginning to end
and more.   By more I mean that it is important to comply with national, state and
local policy and regulations.   Any ad-hock tool is fine and dandy but will not
meet compliance requirements unless it happens to be specified.

If you are a criminal just toss it in the dumpster no one will
find it anyhow.
