Zero-Fill a Hard Disk 1. Determine the brand and model of hard disk you want to overwrite. 2. Download a CD ISO image or a floppy disk image (depending upon your equipment). 3. Restart your computer with the bootable media you created in Step 2. 4. Select the hard disk to zero-fill when.
If your drive supports it there may also be an option to perform an Enhanced Secure Erase which will write set patterns instead of zero’s to the drive. Because the erase is performed within the drive itself, this method is considered more secure and thorough than overwriting with a 3rd party utility.
The “clean all” command tells diskpart to write zeros to every last sector of the hard drive, effectively wiping it clean. You will see a little blinking cursor while it runs, and unfortunately it will not give you any kind of indication of how far along it is or how long it will take.
Every time you run the zero fill process on a hard drive, it writes zeros over your existing data. The more times you run the zero fill process, the harder it will be to recover anything. This process is highly recommended if you are planning on selling a device with a hard drive or flash memory.

It is actually just another write cycle that is typically used when you want to secure erase the information on SSD. Zero-filling an SSD which is not TRIM-capable is a trick used to improve write performance. SSD can write data quickly only to a blank (zero-filled) block.
Running a WD 750GB Black drive on a Dell laptop, Windows 7. I want to do a clean install but first would prefer to do a low level format and reset the drive to a factory fresh state. Previously when I’ve tried this, whatever WD software I attempted to use just would not work and Iwas forced to use a third party disc wipe program, (Kill Disk). I’d prefer to stick with WD. Thank you.
