Any suggestions on what software I should use?

Like the man said, no need to wipe it, the restore operation will overwrite everything.
If you want to know how anyway, here are two methods.
1. Get an image file for a bootable cd with the diagnostic software on it from the manufacturer of the drive.
There may well be an erase utility on that.
Even if there's not, go ahead and run the manufacturer's long test on the drive to make sure it's not fixing to go bad.
2. Go to mfslive.org and download the zip file of the .iso image for the MFS Live cd v1.4 and burn yourself a copy (as an image).
Do that even if you don't have a TiVo, it's handy to have.
Disconnect all other drives except an optical drive to boot the cd in.
When it finishes booting do
and see what it calls the drive you want to erase.
Probably /dev/hda (for a PATA/IDE drive) or /dev/sda for a SATA drive.
If you put it somewhere other than the first controller it might be /hdb or /hdc or /hdd (change h to s for SATA).
dd if=/dev/zero of=/dev/hda
and let it run
(change /hda to whatever's appropriate if necessary)
or if you want to be able to see what's going on
dd_rescue -v /dev/zero /dev/hda
Eventually zeros will have been written to the entire drive.
Just for fun and enlightenment, before you do the erase (if it's a TiVo drive), do
pdisk -l /dev/hda
and have a look at the partition map.
fdisk -l /dev/hda
also show partition info of the IBM/DOS/Windows variety, make sure it's the drive you think it is but otherwise don't worry about it.
The Master Boot Record and the Apple boot page get written in different enough places that the "table of contents" survives even though the contents themselves have been overwritten.
If the image file you want to restore ends in .tbk, then you'll need the WinMFS program (also available at mfslive.org), and a machine running XP or later.
Otherwise it should end with .bak and you should be able to restore it with the tools on the MFS Live cd v1.4 (which is the successor to the old MFS Tools).
Information and instructions on how to use MFS Live and WinMFS also available at mfslive.org
do not know if you have the wrong drive hooked up or have more than one hooked up and specify the wrong one and they'll wipe them just as cheerfully.
(In the event of something like that on a PC drive, there's a command line utility called testdisk on the Parted Magic cd, a copy of which it wouldn't hurt to have on hand either--also free)
