If there is some software that is supposed to keep the info from being
recovered, there is now or will soon be software that can get figure
out how to get past it.

Do you want to use something the "sounds like it might do the trick?"

Just like is used to be okay to remove, then it was okay to put in
recycle bin, then it was okay to empty recycle bin, then it was okay
to overwrite, then it was okay to encrypt, then it was okay to format,
then you needed to low level format, then write all zeros, then write
all ones, then alternate, then random, then you could burn it or break
it, then none of this is good enough anymore as people got smarter and
the need to read became more important, now it is an industry.

There are people that get paid to figure out and write books and teach
classes just on how to recovery your unrecoverable data deleted with
methods that might do the trick. That is all these people do. They
are creative and laugh at things that might do the trick.

Whatever method you choose, chances are somebody is smarter than you
or your method and will know how to piece all or part of it back
together. They know now or they will figure it out if they need to.

Smash your USB device in little pieces, incinerate and melt them in a
blast furnace, add various other elements and compounds, let it
solidify, smash it again and dissolve the pieces in aqua regia and and
dump the solution in the ocean over the starboard side of a cruise
ship a little one day and the port side the next a little at a time
each day on your next month long cruise. That will work for now.

Formatting will not erase the data on the drive. If you find this
incredible, look up "unformatting" utilities.

My question is: If stuff is erased or formatted, etc - Where does it go? I
thought a drive only can hold so much information. Wouldn't it eventually run
out of space?

Are we dealing with nano technology eventhough we are apparently not?

Is all our computer stuff being put into another dimension? I am just
wondering where and if we are dumping massive amounts of garbage or stuff
somwehere. If so I really hope nothing else is there. That would be terrible
if stuff lived there. We would be causing genocide, unknowingly even.

Any answers? Do any mystics, physicists, vast-knowing or all-knowing beings
have any answers?

Surprising and disappointing news, luna. Any clues about the rate of decay?
