Windows 7: chkdsk will not run.......error 766f6c756d652e63 3f1

26 Dec 2011   #31

Check for any installed security software

I don't think if the post author mentioned the message before the 766...3f1 message. I see that error number appear after a message that speaks of some recent software installation (no further description) and to use the system restore functionality to return the system to when the unspecified software was installed (really useful).

I inferred that the software was security related. I was using Norton Security suite at the time. At some point I uninstalled Norton and validated my suspicion that Norton was causing my problem--but the uninstall/reinstall Norton process was unusable to deal with the occasional but not unusual chkdsk problem. I went to their tech support whom couldn't cope with the issue. (They claimed nobody had ever reported the problem before and wanted to do some special tracking, access to my machine, etc., but chkdsk's are a fairly random problem.) There may be (if not, should be) a Norton functionality to adapting the technique I describe below in the context of said 766..3f1 messages; if so, I can't explain why tech support didn't describe it during my abandoned tech support message chain.

At some point I decided to install Outpost Security Suite Pro. I have discovered a two step procedure which always got past my 766...3f1 messages and allowed chkdsk to run as expected in subsequent system boot up (because chkdsk will tell you it can't fix the Windows partition with Windows up):

1) Schedule chkdsk to run after the next system reboot. The reason I do this is because the chkdsk message at boot (with the 766...3f1 message) can be inconsistent, but I knew chkdsk has to be run, so I schedule it: right-click the C: drive (via My Computer or other disc icons), select Properties, click on the tools tab, click the Check Now button in the error-checking region, and click both boxes (fix file system, scan for...bad sectors) and process. Eventually the system will come back and tell you it can't do it right now, would you like to schedule it? Confirm approval.

2) Suspend the security program until reboot/system startup. (I think, for example, Outpost Security Pro has a right click suspension menu item with 3 options, including the reboot.)

Chkdsk will now run (on least on my HP Win 7 x64 machine) with the security software intact when I subsequently log into Windows.

Windows 7 64

I was having this problem as well - my solution was to uninstall Magic Disk (virtual CD drive program) and this allowed autochk to run and repair the problem at next boot.
