Chances of recovery on the hard drive are exactly the same if you continue
to use it. The likely hood of retrieving the file from the flash drive is
probably 100%.
What was the gist of your question?
I think he means if he moves a file to a flash drive, as opposed to deleting
it, will the file still be recoverable from the HDD.
The answer is yes. When you move a file it is the same as copying, then
deleting the original.
You need some kind of secure delete program to get rid of the file left on
the HDD (used several times).
Basically Windows uses a Table Of Contents (like an index in a book) to
point to the location of the file on the disk. When you "delete" a file
under Windows the "listing" if the file in the TOC is removed, but the file
is left and the space it occupies on the disk is marked as free space (ready
to be over written).
This is akin to erasing a reference to X in a book index, but leaving the
pages of the actual X in the book. So when the index is examined, there is
no reference to X, but if you leaf through the actual pages you will still
find the X material there.
This is basically to save wear and tear on the physical hard disk AFAIK,
also means you HDD is available for read commands.
