I have an external ESATA drive I want to do more than zero, (I would rather clobber with random data, such as the U.S. Department of Defense disk wiping policy), that is free as in GNU/OSS.

Short hand requirements

  • Windows only, x64 preferred but not required.
  • No linux live-CD
  • No virtual OS creation
  • Free/OSS

Surely such software exists, or can exist but my google-foo could not locate it.

Perhaps Windows cannot actually do this? I would imagine it could with a non-system drive, at least.


This question is not an exact duplicate. The linked question (which I read fully before asking) says to use a linux utility. The linked question recommends two linux utilities, only, in the accepted answer! This question is specifically, clearly, and deliberately is asking for a windows only solution, which requires no linux or unix parts. So from my perspective, "exact duplicate" is provably inaccurate. What is the best way to appeal an improperly closed question?

Use HDD Low Level Format Tool and then Sdelete if you want a random re-write... its not necessary though. You should also run HDDScan afterwards.

If it has to be OSS you can use Eraser
