Patrick and rest of the list:
I know of only one way to 'destroy' data and that is to destroy the media it is on. This is accomplished with the use of a 10,000 TON press (yes that is right 10K TON.) Drives are stacked on special pallets and then crushed. It is 'fun' with the new glass platters as they make a real mess. However, you should see one of the old metal platters after being crushed. Then the whole mess is melted in to a 'blob'. I would like to see a data recovery company recover data from this.
However, you can use a 'wiping' program if you want to remove the data from the hard drive, if you plan on reusing the drive. Remove the offending data, back it up to backup media, wipe the drive and then restore. Before going through this process, and it will take a lot of time, you might want to mention that it may be less expensive to replace the drives and destroy the old one's.
If you are in the DOD/DOE operations arenas, you may have no choice but to replace the drives.

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)?
