When Windows 7 is manually put to sleep, or an automatic sleep commences after a period of time set in the Power Options, chkdsk will automatically run upon the next startup of the computer.

To be clear here is an example:

  1. I put the computer to sleep for say 3 hours while I go in another room.
  2. I return back to my computer, waking it up.
  3. After say another few hours of operation I shutdown the computer.
  4. Upon booting up next time chkdsk runs, and always finds no problems.

Running fsutil dirty query c does not indicate the c drive is dirty, and similarly running the command for the external drives connected to the computer does not indicate they are dirty either.

I'm a bit lost as to what to do really. It seems this problem is unique compared to other chkdsk related problems I have read about. Perhaps it has some correspondence with windows being put to sleep?

i sleep my computer every day and only reboot/shutdown when it needs to, to install updates. I've done this since Windows 7 came out and i have not experienced this behavior, so i tend to think it is not related to sleeping the system by itself. have you queried the SMART status of your drives, to ensure they are not physically indicating a failure? – Xantec Mar 25 '11 at 22:04
I can check the SMART status. Not done so before so Any recommended tools and what I am looking for specifically? – camelCased Mar 25 '11 at 23:31
a program like DiskCheckUp should work for monitoring the SMART output of a hard drive. Also, if you know the manufacturer of the drive you can check out their website to download any tools they may have available for checking/testing/monitoring hard drives as well. – Xantec Mar 26 '11 at 1:01
Thanks for the suggestions everyone. Having run the Western Digital Data Lifeguard Diagnostics tool both the external hard drives and one internal drive pass everything. Any more thoughts? – camelCased Mar 26 '11 at 18:49
