    I had started a chkdsk c: /r on my daughter's computer at her home and it got to 58% and froze up there. Now when she holds down the power button and reboots it it goes into the chkdsk again. How do I cancel that chkdsk? I know you can by pass it at startup but I want to cancel it.

    I found this as far as stopping the chkdsk

    1.Start > Run > regedt32
    2.Navigate to HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Con trol\\Session Manager
    3.Open the BootExecute key
    4.Remove the line that says: autocheck autochk /r \??\E: where ďE:Ē is your drive letter
    5.Exit Regedit and reboot, and no scan will execute

    Why regedt32 instead of regedit? They both seem to bring up the registry. Is there a difference?

    I had her try the above after the first 2 times of by-passing the chkdsk at start up. We got to the point of trying to open the BootExecute key and there was none there. I checked my computer and I donít have it either. And these were supposedly instructions for the XP operating system.

    I am wondering now since she seems to be able to boot without seeing the computer wanting to go into a chkdsk cycle maybe because of by-passing it twice if that canceled the scheduled chkdsk and if that is the reason that key isnít there. More importantly now since I had her try twice to run the chkdsk c: /r I am wondering why her computer refuses to complete it and freezes up on the 4 stage once at the above mentioned 58% and then at 46%.

    Thanks.

    In Windows XP (and Vista and 7 as well), you can use regedt32 and regedit interchangeably. In fact, regedt32.exe is just a stub that starts regedit.exe.

    I can't help with the rest of your questions.

    Take a look at this Microsoft explaination of CHKDSK for some insight into the function and what it does and does not do.

    Thanks and I did read it. I am assuming even though it was written for Windows NT version 4.0 Service Pack 4 (SP4) and Windows 2000 it may be much the same for Windows XP if the disk is formatted as NTFS. I see where it says it can take days but I have never seen that happen. I assume you may be saying that chkdsk did not freeze up even though it stayed on 58% for over a half hour. I would like to believe that so I could have her run it again but it just doesn't seem like that was the case since it is not a big hard drive and really doesn't have many sub folders or files on it.

    What about that find for editing the Registry to stop a chkdsk from continually trying to run if we have to shut it down again to get past a frozen screen again? I wonder why that BootExecute key does not seem to be there.

    Thanks again.

    There is a better explaination here than I could give in this limited space and links to some other more through explainations at the bottom of the page.

    The author of the article states, "This article is only a basic introduction to using the Windows XP Chkdsk utility. In real life it is actually far more in depth than this. For instance when Windows XP reboots after initiating Chkdsk it is actually Autochk.exe that runs on reboot!

    Because Autochk.exe can be controlled by setting or resetting registry settings, it is possible to programmatically schedule volumes for repair using Regini scripts.

    These topics are beyond the scope of the average user so I do not discuss them here."

    [/quote]Thanks and I did read every word of all 3 articles yet I still question if the computer can actually freeze as it appears to be doing because it really has very little on the hard drive by comparison to other hard drives I have run chkdsk on which takes an hour to an hour and a half to complete. Also it doesn't answer the question about BootExecute key in that Registry edit not being there. Her computer may already be messed up but I don't want to cause further damage by having her run chkdsk again if it is continually going to freeze up if, in fact, that is what it is doing. I guess maybe I should go with this from one of those articles. "If you use chkdsk /f on a very large disk (for example, 70 gigabytes) or a disk with a very large number of files (for example, millions of files), chkdsk might take a long time (for example, over several days) to complete. The computer is not available during this time because chkdsk does not relinquish control until it is finished."

    It could very well be that CHKDSK is choking on a larg section of bad sectors on the drive, which would indicat an imminent failure of the HD. At this point, I would have your daughter backup all her personal data just to be sure she can preserve it before doing anything further with this HD.

    She could then download from the drive manufacturers webpage the diagnostic disk utility and that should tell you if the drive is on it's last legs.

    You don't mention at what stage CHKDSK is freezing. Since CHKDSK does more than just check file integrity, but also verifies disk integrity, if it is hanging at Stage 5 (free space check) it would indicate a different problem that file integrity. To find out the stage it is freezing CHKDSK needs to be run from the Graphical Interface (My Computer>right click C drive>select Properties>Tools tab>Error Checking-Check Now button>Check both boxes and click Start Now.

    For a tutorial with pictures of this process thake a look here.

    As far as why that registry key is not present, I can't say.

    Sorry I thought I had said it was in stage 4 that it appeared to freeze. Now that I think about it I may have mentioned it in another thread that I broke this problem out of. I have a heck of a time keeping track of all hers and my own computer problems. LOL

    I am having her start a chkdsk/r and let it run for at least 16 hours starting this afternoon. I will take a look at your other link too. Thanks very much for the help.

    It could very well be doing that choking you mentioned since it has been sitting on 58% in stage 4 for 19 hours now.

    Thanks.
