A disk scrubber and a virtualized disk boot system are not at all related. For example, a
disk scrubber could be bypassed by a rootkit, or even another level of filter driver. And
the virtual reboot doesn't scrub the disk, it reinitializes it, leaving anything
previously on the disk still there physically, even though not logically. The
technologies have almost nothing in common. So if I put my secret data on the computer,
and the next student reboots and installs a disk spy program that can read sectors, there
is a good chance that my secret data could be read, because the bits are still on the
disk, on a place that was not reinitialized. You need to look at the various
virtualization prducts and read what they've disclosed about their technology. I've
talked to a couple of them at trade shows back when I was concerned about administering
student labs. Their role is to protect the computer and the network, not to protect
confidentiality of data.
I didn't bother to read the NTFS paper, so I don't know what its relevance is, but
whatever it has, it can't do any harm to understand it.

Jeff, Do you any thoughts? Thank you again for your interest in this.
At the University I study a at we use a piece of software that rebuilds
each windows XP software system at each reboot. I gather this is a
attempt to prevent viruses from attacking the computer itself. The
computer gets the files from the network. My question is why is my
idea so far off?

I would like to start an open discussion:
I have some ideas as to a method to scrub a hard drive on the fly. Of
course my ideas are just that, ideas. My ideas are subject to change
and hopefully we are able to come up with a reasonable method reduce
the need for the sledge hammer method of data theft.
First, my understanding is that the logical block size is
2048 bytes
Second, although a data can be retrieve for ever using a
Transmission Electron Microscope (TEM) or Scanning Tunneling Microscope
(STM) ... This is what returned to after selling my IT firm...
Third, who cares! Most people look at porn, or are
attorneys, medical offices (Have you ever heard of HIPPA) If one of the
medical offices donates a computer and it ever opened a medical file
the doctor is screwed. CAN I GET AN AMEN BROTHER?
Fourth, The idea
If a file is written that is smaller than 2048 bytes then the file will
fit on one block of a hard drive.
Next write a program that when a user logs off the computers and the
computer then reboots its self and when rebooting a program is
activated. The program the writes the said file until the hard drive
has reached its capacity. When the hard drive reaches its maximum
capacity it then sweeps itself 7 times.
What are your thoughts as to this concept? If you use this idea in the
future please reference me (Jason Spalding)
