I have a Verbatim Store 'n' Go drive which by default comes with software in a partition which password protects the drive. I want to erase this partition, as it only works on Windows (I'm having to look at it now through a virtual machine on my Mac).

I've tried using KillDisk to totally wipe the whole thing, but it doesn't seem to work, and this password-protecting partition always remains intact.

Is there any program which will completely wipe a flash drive, no questions asked? Or is there a way to do it through the Verbatim software? I have the password and everything, I just can't find a way to fully format it.

Cheers.

Windows can also do this with the diskpart utility. You'll want to delete all the partitions on the drive, then zero out the drive, and finally create a new partition and format it.

A quick search shows that the drive you mentioned might have U3 on it. You can use the Mac version of the U3 removal software to get rid of it.

Pop the drive in your Mac and run dd with the input as /dev/zero to fill it with zeros:

you'll probably need to mount it first:

mount /dev/sda1 /mnt

then wipe it:

dd if=/dev/zero of=/mnt

change the drive location accordingly.

Hi. It appears to be already mounted: "/dev/disk3s0 on /Volumes/V-Secure (cd9660, local, nodev, nosuid, read-only, noowners)". When I try: "dd if=/dev/zero of=/dev/disk3s0" I get "dd: /dev/disk3s0: Resource busy". If I "sudo -s" and "cd /Volumes/V-Secure", I can view the files in the V-Secure folder, which do the password protection. Not sure if I can delete them - if I can, will that work? –  Anonymous Nov 23 '09 at 20:57
    
It should wipe it. Make sure you aren't in the directory while formatting it and no devices are accessing it (eg. it's open in finder) –  John T Nov 23 '09 at 21:02

I would recommend gparted. It has a really easy to use GUI and has never had any trouble with anything, even if I couldn't get it to work with anything else: http://www.brunolinux.com/01-First_Things_To_Know/Windows_Tools_-_Gparted.html
