Hello Ellen,

If you like, you could open a command prompt at boot from your installation media, then run a "clean all" command to do a secure delete of your hard disk drive.

If you had an install dvd you could run the clean all command.

No disk is ever completely clean.

I wouldn`t worry about it, they will wipe it.

Wow, we are quick

how to wipe disk clean, con't

My goodness, you all are fast and so very helpful. When the guy at HP said they'd make sure the drive was clean, I had my doubts: One billion AT&T accounts hacked by an inside employee. In any event, I might try the command prompt thing just in case. Thanks again ever so much to each of you, as always. ellenc

I use CCleaner to wipe drives (in fact, it's the only thing I use CCleaner for). One pass is all that's needed adequately wipe a disk (although I use multiple passes to torture test new HDDs).

I would ask them if the you can either remove the hard drive without voiding the warranty or if they can send it back to you if removing it will void the warranty
