How to easilly lose a lot of data

[minesheep]

how to wipe data. Use at your own risk! no data recover service if misused/misunderstood commands lead to data loss

Code:

sudo dd if=/dev/zero (faster, less secure) or /dev/urandom (slow, more secure) of=/dev/sdx(y)

Examples:
Your internal hdd is sda and you want to wipe partition 1 select one of the commands.

Code:

sudo dd if=/dev/zero of=/dev/sda1

faster, secure enough for you

Code:

sudo dd if=/dev/urandom of=/dev/sda1

more secure, slow

Your internal flash drive is sdb and you want to wipe partition 7 select one of the commands.

Code:

sudo dd if=/dev/zero of=/dev/sdb7

faster, secure enough for you

Code:

sudo dd if=/dev/urandom of=/dev/sdb7

more secure, slow

Your SD card is sdc and you want to wipe whole SD card select one of the commands.

Code:

sudo dd if=/dev/zero of=/dev/sdc

faster, secure enough for you

Code:

sudo dd if=/dev/urandom of=/dev/sdc

more secure, slow

Keep in mind that wiping SSD, SD card, usb flash drives, usb SSD or any solid state media wears out after limited amount of program/erase cycles so don't wipe solid state media for fun.
