1) The file is left intact, one or two bytes of data in the FAT (File Allocation Table) are changed to indicate that the file is no longer there. As far as I know, all other information about the file creation date is left intact. And yes, this is the same for the hard disk.

2) Use 3rd party software that traces these files (there is still information about them) and the space they were occupying, and wipes that space. Or, format the disk. Do not use the Quick Format option, as this just wipes the file allocation table, the data from the files is still there.

3) Disk copy only copies the files. It doesn't care whether they're new or not. No, you could have different files in different locations on the physical disk. It only copies by file name, it does not copy the disk "image".

4) No information about the computer or OS, but there are two directories that are created, so they will have a creation date.
 
Deleted files on Floppy & Hard disk -remnants ?
=================================

1) When you delete a file from a Floppy disk
-what information is left about that file ??

I know that the data may remain for the file, unless it is wiped or
overwritten ?

What about the Fille name, does information on that still exist ??
-about when it was created on the Floppy disk ??
-when it was deleted ??

Is this the same for a Hard Disk ??

2) How do you delete all information about a particular file, when the file
it is deleted ??

3) Does Disk Copy of a Floppy Disk do an exact copy ??

-does it only copy Files that exist ??
-does it also copy deleted data ??
-is the copy an exact mirror image ??

4) What information goes onto a Floppy, when it first formatted ??
-is there any information about the computer ??
-is there any information about the operating system ??
-does it datestamp the floppy when it is formatted ??

Thanks
