It may be off topic but I have a USB hard drive (Lacie-500GB, FAT system, with close to 400GB free space)Becquet said: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 ?
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...)
