I would say still not really. The point of the zeroing process from the VMware point of view is to guarantee that no old data stored on the SAN could be accessed through a new VM. This means the zeroing has to done, just sooner or later (eager or lazy).
Inside Windows it might be the same, but I have never seen it published if Windows does on-demand-zeroing for new files. With a full format in Windows 2008 and later it is however guaranteed that no old data remains.
IF Windows does indeed do a zeroing before new files are located and it keeps track on what has been and not zeroed, and if a full format would change this behavior, then it could be comparable, but unfortunately it is unknown to me.
And thanks for this valuable Info. But why it is different in windows 2003 and windows 2008?
Sometimes behavior changes in the operating systems. Many people using Windows 2003 and earlier might have thought that a full format actually deletes data, but it did not. Perhaps was this the reason to begin to really zero the disk in Windows 2008.
