EDIT: any secure wipe is indeed gonna take while because it writes 1s and then 0s and then 1s again onto each byte so as to not leave any "magnetic residue" for lack of better words. And yes 1 wipe/pass is/can usually be enough but, multipass gaurentees it.

I don't know if it was my UEFI bios that was the problem, but I could not get dban to work. It doesn't seem to like any USB hubs attached to the machine or ACHI enabled or god knows what else. After spending an hr of trial and error, (well an hr of error more to the point) i just said to the heck with this.

Anyway, probably good for a boot drive, IF you can get it to work on modern hardware. But for a secondary for which i wanted to wipe, the disk wipe software i mentioned above is what you want !

You're looking at about 6hrs for a one pass on a 2TB.

It doesn't install into the OS like Eraser has. Just an exe, run it, choose your drive (as long as its not the main o/s boot drive) select your method of wipe, el voila ! Couldn't be simpler ! Why waste your time, on your hands and knee's unplugging everything out of your USB ports, unplugging any additional drives internally, fart arsing around in your bios just to get dban to work, when you can use this instead !

Couldn't you just format it a few times?

Well and perhaps someone could provide some insight as to why, just to satisfy my curiosity. After doing the one pass, and reformatting the drive entirely, it's still encrypted with bitlocker.

To remove the password that i added to encrypt, it said it could take a long time, so i won't bother. I guess Seagate will have their work cut out if they want to properly test the drive. biggrin.gif A little thank you for making such a poor product that cost me endless hrs of frustration ! thumb.gif

Anyway, surely i would have thought that reformatting an HD even if it was encrypted would remove the encryption, but evidently not.

Any thoughts as to why ?

Here is what I do:

 

Grab yourself an Ubuntu LiveCD

Burn ISO to a DVD (or better yet, use YUMI and put it onto a flash drive)

Boot from it

Open terminal

Type in the following command 

sudo fdisk -l

 

This will give you a list of your drives. Look for a drive that matches your drive. (if you are not sure, post what it spits out here and I can help you)

Once you know what drive you want to destroy, do the following command 

 

shred -nzfv 5 /dev/<your drive>

 

if your drive is /dev/sdb then you would do

shred -nzfv 5 /dev/sdb

 

This command will shred the data on the drive, then overwrite it will zeros 5 times while showing progress.  This may take several hours.

Same with windows PE, I use a live boot CD at work with tons ot tools packed in some of them require usb devices and ACHI to be turned off, i'm fairly sure it's a driver issues since they are small and lightweight they don't usually have need the drivers to support such things.
