Selling T43p -- how to wipe C:\ but keep recovery partition?

[thefultonhow]

Long story short, I have a new computer, I am selling my T43p, and I want to make sure I don't have any sensitive data on the computer before I ship it off to its new owner. Is there a program that I could use to wipe just the C:\ partition but keep the MBR and recovery partition intact?

Why not restore it to the factory-shipped image....? You'll be overwriting the disk (some of it), and you can use third party programs to zero out the blank areas.

I was planning on doing that, but I needed to know what kind of third-party program would do what I needed it to. Killdisk didn't work, BTW -- it froze during the boot process, which is apparently a relatively common problem. I ended up just writing a number of large image files to the entire drive.

Google for something called a "wipe disk" utility, Norton Utilities used to have a superb one (worked from a bootable floppy, even). You simply need something that overwrites the unused space with 1's, then 0's, then 1's.

what kind of hdd? if it's a hitachi, you could use the dft utility to test and wipe the drive prior to doing a reimage from product recovery disks.
