Manage-bde ­WipeFreeSpace|-w [] [-Cancel] [-computername] [{-?|/?}] [{- help|-h}]

Wipes the free space on the volume removing any data fragments that may have existed in the space. Running this command on a volume that was encrypted using the “Used Space Only” encryption method provides the same level of protection as the “Full Volume Encryption” encryption method.
