    Disk Corruption (WinXP Pro SP1)

    Booted my computer this morning and noticed it was doing a scandisk or chkdsk. Everything flashed by quickly before I could take note of any messages, other than something about "Administrative Tools". When booting was complete I checked and, sure 'nuff, the Administrative Tools folder was empty. I did a "chkdsk" of the affected drive (D and it picked up some corrupt sectors in a couple of files I can easily recover. A quick examination of the disk shows I have a new folder called "found.000" with a subdirectory called "dir0000.chk" containing some files that look like the contents of the Administrative Tools folder (see attachment). I don't know if all the original files are there. I haven't noticed anything else missing or corrupt. Computer seems to be operating normally.

    How can I recover or recreate the Administrative Tools folder? Is there anything else I should be looking at given what happened?

    Cheers,
    Regards,

    Paul,

    The Found.000 & dir0000.chk are the files created by chkdsk where it finds corrupted data and puts these fragments in those folders, supposedly to be used to recreate or fix the files.
    I have NEVER been able to utilize these files or the data scraps in them. I delete them almost automatically. I'm not sure if there was EVER any problem after dumping these things.

    You can download and restore the Administrative Tools from MS at ADMIN TOOLS

    Running system file checker may insure all your files are intact and you keep running smoothly. You may not need it, but it won't hurt you, and a case could probably be made to run it every once in a while on a busy machine. The next time you run chkdsk I'd run a chkdsk /r from the recovery console as the most effective chkdsk.

    What makes the console version more effective?

    Re: Disk Corruption (WinXP Pro SP1)

    I don't have bench studies or the compelling stats that the statement begs for, and of course the why or what makes it effective if true is key. I've said this 6 or so times. It's offered frequently in groups, and others have found it chkdsk /r from the RC to have the most efficacy. I've compared it with other switches from chkdsk/gui or any command prompt other than RC, and hope you will if the situation comes up.

    Last week Raxco's Windows Technical Windows Manager spoke on topics inclucing disk maint./repair and defrag. He's one of 6 MS MVPs on Win Storage/File Mgt. and agreed with this. I didn't get the why because so many were hitting him up with questions, but I will and I'll also try to get to people at MS who deal with the RC. It should be defined if an advantage and I'll try my best.

    Re: Disk Corruption (WinXP Pro SP1)

    Yeah, it seems like a bit of overkill to me. Running the Recovery Console should be necessary only for "recovery" of some kind, not routine "disk maintenance." Opening a command prompt window to run CHKDSK is intended for routine disk maintenance and error repair. Works perfectly well, including the boot partition, which you know requires the completion of the check at a reboot.....

    Re: Disk Corruption (WinXP Pro SP1)

    Several disk experts stipulate that the Recovery Console has a broader role than back to the wall "recovery" as does Microsoft from 811150. It can be the only effective tool to clear up some "fsutil query" dirty bit problems and endless loop problems when Autochk.exe is called by the kernel and then like the energizer bunny refuses to quit, i.e. Chkdsk runs on start and won't stop. This is showing up frequently in the MS disk and storage groups, and disk and XP sites. Raxco Perfect Disk had their MS Windows Manager, one of 6 disk MS MVPs in for a lecture and he portrayed it as far from "overkill" but instead as a valuable tool. I will to contact MS RC personnel and get the Raxco Microsoft Disk MVP who is Manager of Raxco Windows Support to clarify this himself in the Lounge.

    There have been prior situations in the lounge and ubiquitous on the web when gui chkdsk non RC command prompt chkdsk would not solve the problem and RC chkdksk /r would. This is a far different situation than other RC deployments such as bootcfg to modify boot.ini of a powerful, valuable tool that should be handled with care whose results are not guaranteed.

    Efficacy aside, I think that using the recovery console method would apply to isolated cases. For day to day use, the standard tools do what 99% of users need - and certainly for purposes of this particular discussion.

    Re: Disk Corruption (WinXP Pro SP1)

    I would definitely agree, Mark, and I think experts would and my experience is colored by two "special" times where I have had the problem that I interpret as autochk.exe not quitting--where the ntfs command situation you're familiar with is often evoked to stop it--that people sometimes call an endless loop. This is where the system keeps rebooting and running chkdsk. In other words I don't have any evidence that in normal situations you're doing a better job of finding and fixing disk errors by reaching for RC chkdsk instead of chkdsk from the gui or command prompt and unless and until I do I should not imply it's superior for all chkdks runs.

    218461: Description of Enhanced Chkdsk, Autochk, and Chkntfs Tools in Windows 2000

    In those special situations though, it may be better and I have been helped by going to the RC when I couldn't get out of the situation using a regular chkdsk switch even "r" outside the RC. I want to try to get to some disk experts and ask when is it most effective to use chkdsk from the RC besides a situation where you can't get into Windows?

    Re: Disk Corruption (WinXP Pro SP1)

    Experts.... you use this term frequently, but the word itself implies a lot of things. We are all experts to one another in some form. I heard the term "another Word guru" applied to me the other day at the office, and I contested it. Sure, I know my way around Word, but all I have to do is point that person at the Word board here in the Lounge. Conversely, the person that used that term is, to me, an expert in Oracle PL/SQL.

    My point: don't put so much stock in what "the experts" say. There are a lot of experts, and it is determined by an individual's perspective or level of personal experience. Someone that may be an expert in your own eyes could be or feel like a complete neophyte in the larger picture.

    Re: Disk Corruption (WinXP Pro SP1)

    Thanks for the responses. As it turns out, my D disk is toast and I have replaced it. To clarify my initial post, the folder I was concerned about was the Documents and SettingsAll UsersStart MenuProgramsAdministrative Tools folder that contains the shortcuts that show up in Control Panel/Administrative Tools and optionally on the Start menu and the All Programs menu. The administrative tools/utilities/applets themselves were OK; I just lost the shortcuts to them. I had a friend email me the contents of his Cocuments and SettingsAll UsersStart MenuProgramsAdministrative Tools folder, dropped them in my folder. Everything was OK for a while until my D disk got progressively worse.

    I had done a chkdsk with the /r /f and v switches. It did find and reallocate a number of bad sectors, but I think it was too little, too late.

    One question: chkdsk has a /L:size switch that changes the log file size. Presumably there is a default size. Where is the log file located?

    Cheers,
    Regards,
    PaulB

    I'm not aware of chkdsk having an "L" switch - where did you see that?
    For an XP version of the MSKB article, see
    314835 - An Explanation of the New /C and /I Switches That Are Available to Use with Chkdsk.exe

    I'm also unaware of chkdsk creating a log file. There are some tricks you can try to get it to dump the report to a text file - a search should pull them up or shout if you can't find them.
