This time for good!

Yep it’s true.

As you probably already know previous versions of Windows a full format did not wipe in any way, all it did is a quick format(resetting the MFT) plus bad sector error checking and correction(1).

So from Vista onwards to Windows 7 full format also zeroes the entire disk, thus making the full format process a lot more secure then before.

I found out the hard way while playing with some recovery tools. 🙂

Random garbage would have been better, but not that needed really, since i don’t believe in recovering, after zero only wipe, strings of more then 5 bytes from 10(0) or so megs, even if doing that magic magnetic polarization thing experts were boasting a couple of years ago. From my experience zero wipe is more then enough, and why bother with dozens of passes of all kinds of garbage that lasts for ages, when people don’t even zero wipe.

So if you ask me, this is nothing but good news from Microsoft. ^^

On 25 Feb. a nice set of documents used by Microsoft in aiding the law enforcement authorities with forensics related to Windows Vista and Window 7 were leaked and first published on Public Intelligence.

They are a good read and explain a lot of what Microsoft does and does not do to keep your privacy in place and what kind of risks you are exposed when using these two operating systems and with a little background in security for your self you can start defending your privacy better.

The documents provide a great forensics insight and if you do care about your privacy then you should read them.
