Shredding deleted files

Hi, I really dont know if this is the right spot to ask this question.
If not, pls address me to the right ng or discussion forum )

I am selling my old hardware. I already shredded all recent sensitive
information from my hard disk. However, in the past I used to delete
files with no special precaution, so the disk is full of easily
retrievable old data. My program, Simple File Shredder, only accesses
files that havnt already been deleted.

Do you know a program that accesses deleted files and shreddes them
once and for all? Thanks in advance!

Get a Knoppix boot CD, boot it up, and run the following cmd.

dd if=/dev/zero of=/dev/hda

where /dev/hda is the primary master HDD.

There's plenty that will completely wipe the entire hard drive like
http://www.dban.org/

That may not be what you want to do tho.

Google "free space wiper". Lots of apps listed. A free space
wiper will wipe all empty space and deleted files.

After bootup, go to a console with Ctrl-F1. Best remove/disconnect
all other HDDs. Determine which disks are present with fdisk:

fdisk -l

will list all disks and their partitions. SATA HDDs will show up
as sda,sdb,... IDE HDDs will show up as hda,hdb,...

It is better to use dd_rescue (also in Knoppix),
as it will give you progress output:

dd_rescue /dev/zero /dev/hda

If it the overwtite is very slow, you may also want to activate
DMA with

hdparm -d 1 /dev/hda

This is typically not needed with SATA HDDs, but often needed
with IDE HDDs.

Eraser (http://www.heidi.ie/node/6) is free and will erase both files and
empty space. I like it for its erase option within the context menu of
Windows Explorer. It can also erase the entire disc if the disc is not
needed for the operating system. It comes with the ability to also create a
Darik's Boot and Nuke disk that "securely wipes the hard disks of most
computers."

Yep - I've used Eraser for years. It is great.

Not software, but hardware. A good sturdy hammer, and a screwdriver.
Three or four solid whacks to the top case of the drive to open up the
drive, then score the drive platters with the screwdriver. NO ONE
will ever get at that data again.

Yeah but the person he's selling the hardware to probably expects it all to
still be in one piece and functioning!

Tad difficult to sell it like that, stupid.
