Getting rid of a computer or a hard drive? Does it have sensitive data on it? Just deleting it does not do the job. Even reformatting the hard drive is not good enough.
Deleted data is simple to recover, especially in Windows XP. A data recovery program, often free, is all that is needed to undelete data. What can be done to ensure that prying eyes will never see your data?
Plenty.
Boot and nuke an open source program will completely wipe out any data on a hard drive. It is a dangerous program (i.e. there is no turning back once it erases) so be careful in using it. It meets the DOD (Dept of Defense) requirements for complete eradication of data. A bootable disk or CD is created then the computer in question is booted up and goodbye data.
Some entities such as some government agencies and private parties use drastic measures such as saws, sledge hammers, and grinders to ensure no data is left behind. While this may do the job the hard drive cannot be used again…it is off to the land fill.
There is an easier way to get rid of your data but still be able to reuse the hard drive. In Windows XP you can encrypt all your data files, reformat the drive and you are done. This erases the encryption file keys forever. Perhaps the encrypted files can be recovered but without the decryption key all is lost.
Don’t forget to securely destroy CD/DVDs used to store data. Several paper shredders have a feature for chopping up a CD/DVD. We do not think this is a good enough solution. Once the CD/DVD is chopped up, separate it into several piles and dispose of them separately.
