Task Log.

" Error The program does not have the required permissions to erase the unused space on disk. Run the program as an administrator and retry the operation. "

What should I do ?

It may be off topic but I have a USB hard drive (Lacie-500GB, FAT system, with close to 400GB free space)
after 5hrs and 30min using Eraser to erase free space using 1 pass, I can recover tons of deleted files by Recuva software fast scan ( over 80K files...)

Did the task finish?
And was System Restore enabled on the drive?

There are circumstances in which your results would be quite typical. The free space erase only overwrites space that the FAT has marked as free. I think many users would be surprised to learn how much space is not marked as free! Usually, the better check is to discover whether something that you explicitly wanted erased is, in fact, recoverable.
