Can I make windows 7 freeze for a short period of time, during this time I want it to perform absolutely no action. In particular, the OS should not access to any storage device.

My original idea was to crate an interrupt, however, I think that long interrupt will cause a blue screen (which I want to prevent).

  • Why do you want to do this? What are you actually trying to achieve? – Michael Petrotta Sep 12 '11 at 06:19

    Yes, I want to stop all pending I/O operations. I still don't know how to "Pause" the system, therefore, I don't know how to "Unpause" – hamoub Sep 12 '11 at 06:21
  • Michael: During the frozen time, I want to the power of HDD off (secondary HDD, not the OS HDD). – hamoub Sep 12 '11 at 06:24
  • Why do you need to freeze the system for that? – Sergey Podobry Sep 12 '11 at 07:37

    Well, my OS drive is connected on the same bus as the secondary HDD, when I power off the HDD, the OS disk is getting disconnected for a very short time. sometimes, during this period, if the system is performing some kind of action, it freezes, without any option to recover (hard system reboot is required). – hamoub Sep 12 '11 at 07:43

I can tell you for a fact that this is not possible - if you do this to the primary volume the machine will bluescreen because of a watchdog timer, even for a short time. If you disconnect the drive, it will immediately bluescreen. If you do this to a secondary volume, it will be surprise removed.

If you have less than a team of 10-20 very skilled NT kernel developers / testers, this idea is not even beginning to be practical. What is your scenario and what you're trying to accomplish at a high level?

  • I know. And I'm telling you, that this is *not reasonably possible*. – Ana Betts Sep 12 '11 at 19:29
