Not really. The right tools would be an electron microscope.

Each bit on a disk is a magnetic orientation. There is some tolerance on the determination of a 1 or 0. However, how would you know if something was a 1 or 0 before if it is in the tolerance of being 0 now?

If you are installing applications that do taxes...you paid for that software...why would you put it on a computer you are going to sell?...If you are doing taxes on this machine...chances are you have already *****d it up with other personal stuff...you should really reformat that with a fresh install.
I'm not talking about leaving it installed....

You do realize that a format does absolutely nothing to remove data, right? If you fresh installed an OS on a reformatted drive, I could easily lift old data from it using any number of free tools. Free-space wipe is a great feature.

Assuming the software performed a perfect zero pass. I've definitely been able to recover some data from "zeroed drives" in the past. In theory (and most practice) though you would need to have erased some really important information for someone to want to retrieve it.

Much sensitive oriented erasure isn't just a single zero pass, right?

Partially true, a quick format doesn't delete anything but a full format will zero.
@OP I've heard bootandnuke works great.

Yes, but I've still been able to pull corrupted MP3 and image data off of a fully formatted drive. I don't think that some software does as thorough of a job as others. I would be surprised if software does any probability analysis of the data when recovering, but I guess that's possible?

Isn't that what spinrite does in recovery?

you need this, download/burn iso to cd/boot from cd =NUKE

read the instructions carefully, and make sure you unplug your other hard drives

and it took me 10 minutes to find a cracked program that could recover 90% of data from a formatted hard drive

It's an SSD.. why all the drama. You don't need to 0 out an SSD. Secure erase removes all data from the Flash memory as well as clearing all information from the SSD's memory controller. An SSD is not like a mechanical drive.

@OP: Download Parted Magic, burn it to a disk, boot to the disk, and run the "secure erase" program on the SSD. The Secure Erase will "zap" all of the cells of the flash memory, emptying them, and restore the SSD to its Factory shipped state.
