Win 7 Home, Dell Dimension 9100 desktop.  I have purchased a 2TB WD hard drive to replace a 640GB WD drive.  The old drive has a lot of confidential business information on it that I am planning to delete.  Even after deleting I realize that it actually still there and could be recovered by someone wishing malicious intent.  If I copy or clone the drive to the new one, will deleted fragments be copied to the new drive?  I am considering using Norton Ghost or WD's program to transfer my files.  Afterward I would use a wipe program to completely remove the file fragments from the old drive.  I just want to be sure that I am not copying this info (or fragments) over to the new drive where there would be any chance of recovery.

Unless the copy is done block-by-block, the deleted file fragments will not appear on the new disk -- IF -- the deleted files have already been emptied from the Recycle Bin.  Disk cloning programs operate much faster by copying only valid files, so this is the normal method of transfer.  Block copy / image copy mode usually must be enabled as an option.

Do not wipe the old drive until you are completely sure that everything that could conceivably be needed has been copied.  Then wipe it using Secure Erase, MHDD or your preferred disk utility.
