  Now, a lot of coffee cups latter, I am thinking maybe it is harder to
"securely" delete a single file than a whole disk or partition... since
with just 1 file, you must overwrite the place where the file is
located, and if we want to erase the whole disk, it should be matter of
filling it up to full capacity with some debris data... there is no need
to "aim" to a specific spot...

  Sure! I know forensics labs can do things amazing (or they are
supposed to be able to do them... once I read they can recover files
overwritten 7 times, without much problems, and after that, it becomes
more difficult, but not impossible). I still think the flame torch can
be the desired solution... or... we can always drop the pieces to a
river... but maybe Deagol can find them...

 Best Regards
