files?

A “normal” format actually goes out and overwrites all of the data
on the disk. You’ll know you’re performing a normal format as it takes
a long time.

If you’ve done a quick format, then there may be hope. You’ll need
to investigate “unformat” utilities or file recovery software. Normal
“undelete” utilities will probably not work, as they often assume that
you’ve simply deleted a file. Here you’ve deleted everything. A utility
like GetDataBack might be called for.
(There are others as well. This isn’t something I’ve done a lot of, so perhaps readers
will chime in with some utilities that have worked for them.) These utilities actually scan your entire
hard drive and try to piece back together that which was erased. If not
a lot has changed or otherwise been damaged, you can often get a lot of
your data back.

This is why I say “stop using the drive”. The more you use it, the more
the contents of the drive changes, and the less likely it will be that
your data can be recovered.

You’ll notice I’ve focussed on “Quick” Format, and that’s on
purpose. It happens to be what most people do, which is fortunate,
since data recovery from a complete format gets much trickier. In fact,
in order to recover data from a true, data-overwriting normal format,
you’re typically talking data recovery services and a lot of money.
