Nice article, Kurt, but this issue is not confined to just NTFS
formatted volumes.  With Windows, and other operating systems,
propensity to create temp files and use memory paging, I would never
trust a wiping application to remove all evidences of a file by just
wiping the file itself.  A complete erase of the disk is the only way to
insure that the data is gone.

In response to data recovery after 57+ formats query

The UK magazine Computer Shopper carried a feature article "Recovery
Position" in its March 2006 issue, which can be found here
http://www.computershopper.co.uk and search for Recovery Position. It 
appears that disk erasing programs do not delete the data, if you have
the 
right tools for recovery; however a hammer does work.

No surprise there.

Pretty much all the programs fail with NTFS alternate data streams,
files 
that are hosted in the NTFS MFT, or simply fail to wipe normal files at
all.
