How to Zero-Fill a tough Drive With the Format Command

Start at Step 6 if you would like to write down zeros to a drive aside from the first drive in Windows Vista or later; you will need to possess an elevated prompt window open and prepared .
1.Create a System Repair Disc in Windows 7. As we mentioned earlier, you will need access to a Windows 7 computer to make a System Repair Disc. However, it doesn’t got to be your Windows 7 computer. If you do not have a Windows 7 PC then find a lover that does and make a System Repair Disc from his or her computer. If you do not have already got or can’t find how to make a System Repair Disc then you will not be ready to write zeros to a drive during this way.
See our Free Data Destruction Software Programs list for more options.

2. Boot from the System Repair Disc and await the Press any key else from CD or DVD… message after your computer activates , and make certain to try to to that. If you do not see this message but instead see the Windows is loading files… message, that’s fine.
3. Wait for the Windows is loading files… screen. When it’s over, you ought to see a System Recovery Options box. Change any language or keyboard input methods you would like to then select Next >.

5. Select prompt from the System Recovery Options screen.

6. At the prompt, type the subsequent , followed by Enter:
format e: /fs:NTFS /p:2
The format command utilized in this manner will format the E drive with the NTFS filing system and write zeros to each sector of the drive twice. If you’re formatting a special drive, change e to whatever drive letter you would like .
Important : A single pass of zeros to a tough drive should prevent all software based file recovery programs from extracting information from the drive, which the format command in Windows 7 and Vista does by default. However, you would possibly do two passes via this method just to be safe. Even better, if you want to guard yourself from more invasive ways of recovering data, choose a real data destruction program with more advanced options.
