I have an old Dell PC that I am going get rid of to someone. Will a factory reinstall (64-bit Dell OEM W7 HPE and its programs) from its DVD be enough to clear my data on its old SATA HDD?
quote:At the prompt, type the following, followed by Enter:
format e: /fs:NTFS /p:2
The format command used in this way will format the E drive with the NTFS file system and write zeros to every sector of the drive twice. If you are formatting a different drive, change e to whatever drive letter you need.
