Mint Installer should be able to securely erase a hard drive
Recovery of supposedly erased data from magnetic media is easier than what many people would like to believe. A technique called Magnetic Force Microscopy (MFM) allows any moderately funded opponent to recover the last two or three layers of data written to disk. So, I think Linux Mint installer should give us an option to permanently destroy data on our hard drive and make it unrecoverable so that we can install Linux Mint on any PC we want to sell or donate. It should be able to do what other applications do, namely:
1- Active@ KillDisk http://www.killdisk.com/
2- Darik's Boot and Nuke (DBAN) http://www.dban.org/
3- diskwipe http://www.diskwipe.org/
4- Ultimate Boot CD http://www.ultimatebootcd.com/
5 shred http://www.howtogeek.com/howto/15037/us ... ard-drive/
6- HDDErase (application)
7- Parted Magic (application)
8- Wipe and secure-delete
This would be useful for users and computer manufacturers alike

Yep....what Previous1 said.
But we don't want that built into the installer...'cause then folks would be zero filling their hard drives, unaware of what that means. Then claiming "OMG, Mint ate my data"!

blkid is part of util-linux, that should be installed on any linux distro. What it does is show your various drives, for me it givesZorba wrote:Thank you previous but when I run this command line and I didn't get anything If I want to erase the entire disk which command line should I use? because:

wipes one partition only?
Code: Select all
/sbin/blkid
/dev/sda1: UUID="<somenumber>" TYPE="ntfs"

/dev/sdb1: UUID=<somenumber>" TYPE="ext4"
/dev/sdc1: LABEL="<somelabel>" UUID=<somenumber>" TYPE="vfat"
The actual drives are in the /dev/sd(letter) format, the partitions are in /dev/sd(letter)(number). The root (ext4) partition /dev/sdb5 is the OS partition, ntfs /dev/sda1 is my windows drive (1 data partion only), vfat /dev/sdc1 my flash stick... look at the labels and types.
To blank the drive take the respective /dev/sd(letter), and put it to
