The so called smart ass solution is the ONLY sure solution.
No erase program will totally wipe all the data.
Dban is one of the best, and people have been able to still see data, after days of running it, and they are using simple programs, not what the FBI has.
Maybe if you wrote 0s to the drive for a year, it would get everything, but I doubt it.

wekk thats interesting... but even so, it will erase some of the data... and being able to actualy recover it and compile it together will require quite a lot of time... if someone has the patience and time to sit for hours and days tring to recover it, then go right ahead. people at agencies get paid for doing stuff like that...
cant sell a laptop with a broken drive you know...

What happens when you "erase" or "delete" a file in Windows is the entry in the file table is deleted, and the area previously occupied by a meaningful file is designated "free space" which can be overwritten at will by any program that needs it. Both HDDs and SSDs work identically in this regard with OSes like Windows.
When you use a "drive erase" like with CCleaner, what the utility does is write random 0s or 1s on top of all of the storage space so that it's difficult, but not impossible, to recover the previous state of the files. That's why we're saying that the only sure way to prevent anyone from ever getting any data from your storage drive is to physically destroy it.

Just to add to the difficulty in erasing, even if an area of the drive is completely filled, or for that matter the whole drive is filled, that doesn't hide all the previous data.
The places that the drive writes to the disk is only a general area, and it doesn't write to all the area of the disk when it is full.
Every time you fill the disk, it writes to different random areas, leaving previous data.
You have to be careful with SSDs and use the right program.
Erasing wares them out to some extent.
Edit
I agree for the average sale of a laptop or a desktop, erase programs are just fine, I just didn't know how secure you wanted.
