Unavailable to whom?

To you, yes.  To a corporate spy, or government sponsored spy, not a chance.

What is the data worth to someone else?  And, what are the
consequences of someone getting the information?

The only DoD acceptable wipe, at all levels of secrecy, is complete
physical destruction.

And never forget that sparred tracks can never be wiped!  No program
or operating system ever has access to them without modifying the
disk's firmware.  When was the last time that you intentionally or
accidentally updated the firmware on a harddisk?

If your client is worried about confidentiality at DoD levels (and
there are many), you better be very clear on what level is required,
act responsible, and do the right thing -- there are consequences!
