Another utility available on Source Forge will allow you to delete ALL of the files in free space and the entries that are flagged as deleted in the MFT. Recuva will no longer list them. It is Eraser 5.86. I tried others (of note PGP and Sdelete) to no avail. Eraser worked for me.
'If you erase a whole drive, Eraser will not clean the MFT/FAT. To do that you need to format the drive - think this is what BCwipe does. Formatting is the only way to safely remove the ghost entries from the MFT/FAT. So after erasing a drive you need to finally format it. Equally you will be able to recover 'data' from these files but only the erased information and not the original data.'
and this....
'You can choose whether filenames are cleared or not, and Eraser can even clear names of all previously deleted files (when erasing unused disk space).'
I suppose it depends what clean, clear and erase means. I haven't the foggiest, as I don't use eraser.
