Wiping Free Disk Space


Attention! Wiping free disk space for SSD devices is not required in most cases. Read the File Erasure on SSD and HDD devices page for details.

R-Wipe & Clean disables wiping  free disk space on such devices by default. You may enable it, but you should understand what you are doing. The only important part that should be cleaned even on an SSD device is MFT on NTFS disks. The best wiping algorithms for that are zeros or pseudo-random numbers.

Disk data you can wipe depends on your user account type and Windows version.
