erasing the hard drive

Postby Linda on Fri Feb 12, 2010 9:49 pm

I would like to pass on my old Gateway laptop to my daughter. How do I erase all passwords, credit card numbers, etc?

Linux Mint is funded by ads and donations.

It depends on how thorough you want to be. Running GParted and creating a new partition table then reinstalling Mint will eliminate all addresses and directories but the data itself can still be retrieved by anyone with the right knowledge and software.

Programs like Active Killdisk( http://active-kill-disk-hard-drive-eraser.filecart.com/ ) and Darik's Boot and Nuke ( http://www.dban.org/ ) will overwrite the disk with anything from one pass of all zeros to 34 passes of random characters followed by one pass of all zeros. The idea is, the more times the data is overwritten, the harder it is to retrieve.

The downside is time. It can take 1-3 hours to do a single pass all zeros wipe, depending on the size of the drive and the speed of the computer. And, of course, more passes means more time.

also please keep in mind that what aging technogeek suggested will leave your computer with no operating system and you will need to either have your windows install disk or your "Recovery disk" to reinstall Windows or you can go the Awesome way and put linux! :wink: hint hint. :D
