Utility to wipe hard drive?
 

What utility can I use to zero the hard drive? I don't want to just format or repartition. I need to completely obliterate the data.

Another option to what 2damncommon suggested:

System Rescue CD

You can also use the dd command in Linux but that is kinda tricky to use so you have to be a bit careful.

Depending on the options you use with dd command it can take a few minutes to several hours depending on those options. Also even longer if drive is USB connected.

Assuming the drive that you want to shred is /dev/hda.

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

Then repeat the commands several times.

I second what Electro wrote, and further, boot with

write a shell script according to this post:

like the example about half way down the OP for seven passes of random characters over the entire disk.

Personally I like using shred (from a Live CD or USB memory maybe??); man shred
