Tyler, it's a complex task, but data recovery is a widely-used and known thing. A simple reformat simply marks all the data as being empty space on the drive, ready to be written over. It DOES NOT remove the data or magically make it disappear. The 1's and 0's, represented upon the HDD platters in what amounts to magnetic grime, doesn't change. The data can all be easily recovered.

A reformat is like going into a library and removing the dewy code from the spine of every book on the shelves. The books are still there and it doesn't prevent anyone from accessing those books, it just makes it difficult to find them. Your OS can't understand until things are cleaned up, and that isn't very hard for any low-watt data-recovery app or person.

There are only two options for completely destroying the data on a drive. The first, and most obvious, is to destroy the drive. For most people, just breaking it and tossing it in the trash is enough. The FBI, NRO, and the military branches, grind their drives up to a powder.

The other way is to use a data-shredder, which is a generic term used for any deletion method that perminantly destroys data without destroying the drive. At the low end, these are usually just tools that over-right files or drives with a single binary digit (1 or 0). More advanced processes overwrite the file/HDD with several passes of randomly generated 1's and 0's. The effect is like taking a JPEG, then randomly arranging the pixels. Then randomly arranging them again, and again, and again, until yer left with nothing but a gray picture with no details or paterns left.

Done deal. Take your pick.

I did an "idiots delight" and reformated and installed windows on a back up HD containing 6 years of recording studio audio sessions (they were 80% backed up to DVD) but two new CD projects were not! So with the drive reformatted and XP pro reinstalled.....I thought thewave files and sessions were toast! I bought a program called GetDataBack for NTFS file recovery. It ran for 3 hours and 99% of the data was recovered flawlessly! Whew. yep, it's still there if you get stupid!!

overall i think the general idea of wiping is for those who are selling their hard drive, i have succesfully recovered data using software after a reformat so thats definitly no good, 1 wipe is all anyone should bother with less your doing illegal work.

although its expensive, i have seen in news of hardware forensics being used on kiddie porn freaks. also one in great britain i think on some hacker...also if your suspect in releasing a virus that has cost alot of money.
so even though forensics is expensive, dont doubt they wont afford it if your a suspect in almost any computer crime. if so just drill a hole in it, burn it then bury it in the woods

don't forget to put it in a paper bag before you bury it!

no, you don't need a magnet or anything that will damage one's hard drive to "permentantly" erase one's harddrive.. just need to over write it enough times so that any ghost file remains is killed..
you right the goverment standard is 7 time. Partition Magic wipes it 10 different ways so they go over the government standard

I wanted to know if anybody know how to erase a file completely instead of just right clicking and selecting delete and goin to recycling it...
it looks like you want to wipe something clean within windows.

as killian 45 posted an article about it, Evidence Eliminator is the best, because as long as you are not into kiddie porn, nobody is going to go through the effort to recovered those files.

or you can google shredder programs
