Shred is dacht ik niet zo goed, wipe is beter, maar dban is het beste,
en dan weet je zeker dat het leeg is.
Je kunt met het programma "disks"(of schijven), ook met nullen overschrijven,
dit kun je bij formateren kiezen,
maar als je zeker wilt zijn, dan is dban het beste.
Via google opgezocht,
dd if=/dev/urandom of=/dev/sdX bs=1M *replace X with the target drive letter.

sudo wipe /dev/sda1
of

dd if=/dev/urandom of=/dev/hda

If you for instance want to wipe /dev/sda5, enter sudo wipe /dev/sda5 command.
It will ask you to confirm the wipe operation. Type ‘Yes’ and
then hit enter to begin the disk wiping operation.

The time it takes to completely wipe the disk depends upon the size of disk.
Once finished, mount the disk again to verify the disk wipe operation.
Apart from permanently deleting the data, wipe command fills the disk with random data.
To quickly wipe the disk, you could use –q switch to instantly perform the operation.
The –q switch makes 4 passes on each file residing in specified location. However,
if you want to specify the number of passes, use the –Q switch. Furthermore,
if you’re a wiping data from a specific location, you can use –r switch to include
sub-directories present within the root folder. The –f switch forcibly performs
the disk wipe operation. It must be noted that –f doesn’t prompt you to confirm
the action, so you need to make sure that you’ve specified the correct device
identifier to prevent loss of important data.
