Dc3dd is truly an impressive tool, not only can it be used to image a drive but also to wipe it. Previously, I made extensive use of DBAN for erasing data from drives until I came across a problem where DBAN could not see them. Now I use dc3dd, below are the three available options that that users can choose for how the drive will be overwritten.
- Overwrite using zeroes, this is the basic and simplest form you can use for wiping a drive:
- Overwrite using HEX pattern:
dc3dd wipe=/dev/sdb pat=009900
- Overwrite using Text pattern:
dc3dd wipe=/dev/sdb tpat=ireallylikecake
Which ever option you choose the output will look like the following.

If you like you can start multiple instances of dc3dd and wipe more than one drive. Take caution, you don’t want to wipe a working drive by accident. Feel free to comment, I will answer in a timely manner.
