I have a new Sony Vaio CS118 that I am selling, however I need to have the data overwritten or erased. I have found a program called "Eraser" but as far as I can tell, that will only work with data that hasn't been deleted yet. I deleted everything already. What would you guys recommend?

I'm not sure what other information you need. I want a good program (preferably free) that will wipe data on your harddrive. With Eraser, you have to choose your files and then it will overwrite them for you. I have already deleted the files so I don't have access to them. Problem is I just deleted them regularly through Recycle Bin.. I need something that can permanently erase them.

Be careful you don't wipe out the recovery partition

Having grandkids is God's way of giving you a 2nd chance because you were too busy working your butt off the 1st time around

It's not clear if you want to wipe the whole drive clean (includes your data, registry, program settings you made, all programs you have, most recent file use, your favourites, cookies, etc), OR, as I gather garmanma thinks - just your data and leave the system recovery intact.

To wipe the whole drive so nothing is left, no system, no trace, nothing, DBAN is it

It takes hours for all the military standard passes, so a desktop fan makes sense to have on hand :thumbsup:

Either of the two applications will do a good job, as far as what it was designed for. Short of taking a torch to the hdd there are forensic techniques using an electron microscope that can retrieve information. Unless this information is very sensitive I would just overwrite it once and let it go at that.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
