In cases of selling or disposing the hard drive or any external drive overwriting the drive for several times is recommended for security purposes. Many government institutions have specific wiping standards for data wiping. Particularly, the U.S. Department of Defense specification 5220.22 standard says a file must be overwritten three times.

Drive wiping is beneficial for data privacy, since most delete functions don't really delete your data. When a file or folder is selected for deletion, the operating system designates those sectors that your files reside in to be re-writeable. However, using data recovery software those deleted files can be easily restored. Even if you have saved new data to your drive or reformatted, there's still a possibility that the partition can be rebuilt and files can be restored.

Due to these selling or disposing off a PC creates a serious threat. If you haven't properly erased the disk, others can reopen and rebuild your personal data. Hence, Remo Drive Wipe erases the drive data permanently such that no recovery software could ever retrieve your data. Moreover, the tool is available free of cost.
