In my previous article on PC Inspector File Recovery and SuperShredder, I showed how easy it is to recover or “unerase” supposedly deleted files. I also showed how equally easy it is to completely erase files so they can not be recovered.
Darik’s Boot and Nuke (”DBAN”) is a self-contained boot floppy that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.
I always use this program when I am about to sell a hard drive or a computer. All I have to do is insert the floppy disk, restart the computer, and type “autonuke” in the prompt. It will do the rest.
Take the precaution to “please clearly label your DBAN boot media [floppy disk or CD-r] because it is dangerous.” The data will be completely unrecoverable. DBAN uses complex algorithms used by different security and government agencies. It utilizes the data wiping schemes of the following:
These wiping schemes are different methods organizations repeatedly and randomly overwrite data. In addition, DBAN will also do a Quick Erase scheme which just fills the hard disk with zeros.
So, this concludes my discussion on data recovery and proper data disposal. Use PC Inspector File Revocery to easily recover data. If deleting individual files, use SuperShredder. But, if entire partitions or hard disks need to be erased, use
