Additional Secure Erase / Wipe Information

After you have copied out or made back-ups of the data you need to save to external media and want to do a complete wipe secure erase of the entire Hard Disk Drive / Solid State Drive, have a look at Step One of the Optimize tutorial below then boot the Windows installation media to start the Windows 7 installation process.

Whether you use diskpart to run either the clean all command to completely wipe a HDD / SSD or just the clean command to remove the format configuration data and don't use diskpart to create at least a single partition to do the installation to, letting the Windows installer do the format, the new Windows 7 System Reserved partition will be automatically issued, if you want to make your own decision whether this partition is added, study these two (2) options below.
  • If you do not want to create the new Windows 7 "System Reserved" partition use the outline in Step Two #2 to create, format and mark Active a single 100GB partition to do the installation to.
  • If you do want to create the "System Reserved" partition use the outline in Step Two #3 to create, format and mark Active the System Reserved partition and then create and format the 100GB partition to do the installation to.
Either way, running the clean all then creating and formatting the partition(s) using diskpart will get you the best possible space to do a clean install of Windows 7 to; you can always extend the Windows partition to include the remaining unallocated space on the HDD / SSD or create additional Primary partitions or an Extended partition after the installation completes if you choose.
