Well if that title was not a mish mash I don't know what is. Here goes.
I have run into three cases lately where Diskeeper is running on the suspect machine. Funny, in two of the cases (Lenovo laptops) the owner did not even realize the Lite version of the program was even installed. The other was a server.
In all three instances large portions of what I wanted to examine were files full of zeros. I want to run some tests to see if I can document what Diskeeper does when it is moving files around while optimizing the discs (does it write zeros?), or if this is even a Diskeeper issue (I did not find any wiping tools).
My test OS would be a couple of VMware machines, 1 XP & 1 W2K3. What I want to do is write all FFs to the drive so I can easily see changes. But I am trying to think out loud about the best way to do this. Should I get a drive and write FFs to it and then setup the VM environment or should I setup the environment and try to write FFs to the free space in the virtual machine?
Again, just thinking out loud here so any thought or suggestions or obvious Duhs that I might be missing, please comment. And if I am totally off base on my methodology, jump right in. Thanks.
