Advices and additional info on Wiping Hard drives
- If you use one of the bootable tools which I have noted above, the wiping procedure will be independent form the OS. This also means that you can use exactly the same process to wipe a hard drive if you are using Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, Linux, or any other PC operating system.
- Since the introduction of Windows Vista, the format process has been altered and to each standard (non-quick) format a single write zero pass is applied. In case a single write zero pass gets the job done for you, then you can assume that the drive has been wiped clean even after regular format in Windows 10 all the way to Windows Vista. But if you insist on something safer, then you can safely continue following the hard drive wipe instructions above.
Remember that you are wiping only the partition which you are formatting. If your physical hard drive has more than one partition, then it will be necessary that you format those additional drives.
In order to ensure that all of the files you have just deleted will be permanently gone, then it is recommended that you use data wiping tool. You can check this list Free File Shredder Software Programs for suitable programs to “destruct” individual files in accordance to your needs.
