I have to believe that it is more than secure enough for general users who want to be sure that personal and financial info cannot be retrieved from discarded computers and drives. That is three passes of writing, though I don't know if that technically qualifies as a "DoD" wipe as offered by dban and Eraser.
That command will write random data to the entire drive twice, then a third pass writing all zeros. sudo is to have superuser or elevated access to run a command (booting with a live CD or usb shouldn't ask for a password) shred is the program to run the -fvz switches are Force, Verbose, and Zero - the zero means the last round of writing will write all zeros to the drive iterations is the number of passes it will write and the /dev/sdb is the target drive (your drive may vary, use the command "fdisk -l" or "sudo fdisk -l" to list your drives - you should be able to identify it by size). In case someone reading isn't familiar, I will break down that line. I am going to paste a reply to a post from a while ago where the person asking was maybe not as savvy (and I think they had little linux experience): If you can boot with a linux live disk of some sort, you can use shred, which is included in most the common OSs.
First thing you want to do is to put all the hard drives on the server in a raid0 config, then follow the following steps to get the tool to detect the drives:ġ.Boot and run the disk so it comes up with the error that it can't detect any drives, then press ALT-F4 and Enter to get a shellĢ.Go to the /etc/init.d folder and edit the script file named "main"ģ.Search the file for SD_FOUND and modify the "/dev" section of the line to say "/dev/cciss"Ĥ.In the same line of text toward the end, change "sd" to say "c0d"ħ.It will be able to detect and wipe the drives now. However, HP servers do not get their drives detected by this disk by default. Using the "Derrik's Boot and Nuke" cd is the currently accepted way to delete all data securely from hard drives. Here's what I had to do to get DBAN to work on older HP gear: Since at least some of your gear is re-branded HP servers, then you may have the same problem.
