One more comment:
There is no way to completely clean a hard drive of data that was written to it. This has been proven with a court case where a pervert was sent to jail after a special FBI agency was able to recover evidence from a supposedly 'wiped' hard drive (yes, he used DESWIPE, which had overwritten the drive seven times.) They explained that the head drives something like a six-lane highway, but due to misalignment of the drive's heads and the track it drives, there remains something like a six inch to two feet overrun that the head never writes to again. In this area is where they revovered the evidence.
This is why the government requires removal of old hard drives (at least where I work) before systems are handed over to non-government entities, including the on-base school.

This is the dod application for standard Fly in your Soup issue..
You would still have to remove the data in question.. Remove all the
backups with that Fly..
Then Wipe drive and restore older data..
But one thing is for sure.. If it is military stuff... Better follow the
Instruction or you might find yourself in Ft. Leavenworth..
Not the Visitors section either..
Have fun.

I am simply trying to generate a list of options with pro/con for each
to determine how much effort they are interested in going through to
eliminate data. But to the best of my knowledge in this type of a
situation a tape would be magnetically 'cleaned'...or in the case of
hard drives and such they do a series of 0 and 1 alternating writes to
all blank space to ensure that data cannot be read....thanks for the
response

If you are using Oracle, you can do a table reorganize. This compresses
the data and gives some level of certainty that the data on the physical
device is overwritten.
What do other apps that fall under this umbrella do to clean data from
their databases? Also, how is the data removed from other storage
mediums (tape, replicated servers, etc)?
