Get rid of a CDFS partition

Is there a way to get rid of the backup software that comes with click free hard drives on a CDFS partition.

First of all, it's impossible to remove the partition by formating the drive with disk utilities because it's not seen as a real drive.

I also tried to delete the partition using pdisk (on terminal) :

pdisk /dev/disk2

it told me : "Floating point exception"

(I found out that disk2 was the name of the drive)


I even tried to wipe everything on the drive with :

dd if=/dev/zero of=/dev/disk2

but it told me : Permission denied...



Feel free to ask questions if i'm not being clear enough!

solution

For those who have a clickfree hardrive and wonder how to remove the automatic backup software installer partition on the drive..

I figured that this software was not on the actual hard drive.
It is apart on a flash drive or something.

So the only way to get rid of it is to open the hard drive enclosure and to physically remove it **What will void warranty!**.

It is possible to wipe the whole drive booting on debian and using the dd command :
dd if=/dev/zero of=/dev/nameofthedisk
**be carefull to write the right name of hard drive!
If you write an other hard drive name,
you will loose every data you had on it.**
(You can find the name of the drives using the command : fdisk -l)

(you need to be in root mode, type : sudo su)
You will write zeros on the whole drive.

So you will be able to use all of your drive's space.
You will only have to manually mount the partitions you want and to unmount the software installer disc (flashdrive or whatever) when you plug in the usb device.
