I would like to schedule a task to perform scandisk, does anyone have any suggestions on how to use chkdsk to do that? Thank everyone very much for any suggestions1 person got this answerI do too

You can run chkdsk in Windows, but you can't repair errors unless you schedule it to run on boot up. Then it will correct any errors it finds, then boot into Windows.SC Tom-There's no such thing as TMI when asking for tech support.

Could you please give me any suggestions on how to set schedule to run chkdsk on boot up for every Sunday at 12 PM?I prefer using schedule task, which has option to startup window under hibernation mode.1) startup window under hibernation mode using schedule task2) restart window and run chkdsk3) after chkdsk, go back to sleep mode using hibernationDo you have any suggestions on how to code a batch file to perform above task? Thank everyone very much for any suggestions

Not sure how you would set that up in Scheduled Tasks, but here are some of the commands you'd need to;1. Restart Windows: ""%windir%\system32\shutdown -r -t 01"2. Hibernate Windows: "%windir%\system32\rundll32.exe PowrProf.dll, SetSuspendState"Both of these would be without the quote marks.This all brings up the question, what is happening to your PC that makes youfeel that it needs to be checked weekly? XP does a pretty decent job ofmanaging itself without user intervention.SC Tom-There's no such thing as TMI when asking for tech support.

Do you have any suggestions on how to code batch file to restart window for running chkdsk?Or can XP run chkdsk without restarting window? so I can hibernate window after chkdsk?Do anyone have any suggestions? Thank everyone very much for any suggestions

If you let it run it should find and correct any disk errors and Windows should boot normally after the disk has been checked.You don't need to run chkdsk as a regular maintenance routine on your disks, chkdsk only needs to be run if you suspect disk or file system problems, you can run for years without running a chkdsk.Use two batch files to restart Windows and run chkdsk on the boot volume (the Windows drive, assumes C:) and hibernate the machine after chkdsk is done.The first batch file will shutdown the machine and run chkdsk. The file will also set the machine to run a second batch file and hibernate when the machine starts after chkdsk is done.Batch file #1, (Copy the stuff between the --- lines ---): -------------------chkdsk.bat-------------------------------echo y|chkdsk C: /Fschtasks /create /tn Hib /sc onstart /tr c:\hib.bat /ru ""shutdown -r -f -t 0------------------------------------------------------------ Batch file #2. This is the hib.bat batch file that is scheduled to run when the computer starts after the chkdsk is done. The Schtasks command in the first batch file schedules the file to run. You must place the file in the location called by the Schtasks command, in the above command the file is called from C:\, place in that location or if you want to save it in another location change the chkdsk.bat file accordingly.-------------------hib.bat------------------schtasks /delete /tn hib /fPowercfg /h onRUNDLL32.EXE PowrProf.dll,SetSuspendState------------------------------------------- John

Thank everyone very much for any suggestions

Chkdsk cannot run onthe Windows drive because Chkdsk needs an exclusive lock on the driveand it cannot get that exclusive lock while Windows is up and running,that is why the chkdsk must be scheduled to run at boot time.In the case of a data drive chkdsk can easily dismount the drive and getan exclusive lock on the drive, if you run the above "echo y|chkdsk D:/F" on a data volume it will dismount the volume (if files are open) andit will then proceed to immediately run chkdsk on the data drive whileWindows is up and running, there is usually no need to schedule chkdskto run at boot time on data disks.What you are wanting to do is becoming increasingly complex, you wouldneed to have the batch file open a file on the data drive then you wouldhave to pipe the output of the chkdsk command and use "IF" statements in the batch file to answer the questions asked by chkdsk.There are two ways to have Chkdsk run when the computer starts, Autochkwill run if you schedule it to run or by default it will run if thevolume's dirty bit is set. If the operating system detects problems itwill automatically set the dirty bit and the volume will be checked atthe next startup. The dirty bit can also be set manually with thefsutil command but it is best not to do this and to leave the setting ofthe dirty bit to the operating system. Once set the dirty bit cannot bechanged and while the boot time check can be skipped it cannot becanceled, on the other hand, a scheduled Chkdsk without the dirty bitcan be canceled at any time. Scheduled disk checks are recorded in theregistry at the BootExecute value at theHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager key.You can export the value for scheduled chkdsk then merge them at anytime to re-schedule them. To schedule a Chkdsk at the next reboot:On the Windows volume, assumes the volume is C:At the command prompt issue:chkntfs /d(this will reset the BootExecute value to its default and cancel any disk checks that may have been previously scheduled) then run the chkdsk commands:chkdsk c: /fChkdsk will return a message telling you that it cannot lock or dismountthe volume and ask you if you want to schedule a Chkdsk at the nextrestart, answer Yes.For dismountable data volume D:Open a file on the volume, or explore the volume with Explorer. Then atthe Command prompt issue:chkdsk d: /fChkdsk will inform you that the volume is being used by another processand it will ask you if you want to force a dismount on the volume,answer No. Chkdsk will then ask you if you want to schedule a Chkdsk atthe next restart, answer Yes.Now the drives are scheduled to run at the next restart. To do this ina semi-automated manner, after doing the above:Using Regedit export the[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager] key.This exported file will be fairly large, edit the saved file andremove/delete everything except the BootExecute value, the edited filewill look like this:==========================================================Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager]"BootExecute"=hex(7):61,00,75,00,74,00,6f,00,63,00,68,00,65,00,63,00,6b,00,20,....... with a long series of numbers.=====================================================(Leave a blank line at the end of the file.) You only want to save theBootExecute value, nothing else!Save the edited .reg file and when you want to schedule the Chkdsk mergeit to the registry, for example:regedit.exe /s "c:\BootChk.reg"If you want to cancel all scheduled Chkdsk at the command prompt issue"chkntfs /dYour first batch file could now be like so: Batch file #1, (Copy the stuff between the --- lines ---): -------------------chkdsk.bat-------------------------------regedit.exe /s "c:\BootChk.reg"schtasks /create /tn Hib /sc onstart /tr c:\hib.bat /ru ""shutdown -r -f -t 0------------------------------------------------------------- Without having to muck with registry files you can set the dirty bit on volume D: instead, the batch file could look like this: ------------------chkdsk.bat-------------------------------echo y|chkdsk C: /Ffsutil dirty set d:schtasks /create /tn Hib /sc onstart /tr c:\hib.bat /ru ""shutdown -r -f -t 0------------------------------------------------------------ John

Just do following once a week (usually before going to bed) [save as btch file e.g. ckdkwk.bat]---------------------------------Start /wait CHKNTFS /d C:CHKNTFS /d D:CHKDSK /f /v /r /x D:CHKDSK /f /v /r /x C:===================You can add E or F if you have more partitions. Waht this does is it thouroughly checks your hard drive bit-by-bit to make sure you do not have orphaned file (or corrupted files). This command may take 2 to 8 hours depending on you hard drive size.Also use DEFRAGGLER to defragment drive once a week. If oyu have downloaded say files > 500MB, it can fragment your $MFT into 3 or more. To defragment $MFT, use PAGEDEFRAG which is part of SysInternal Suitehttp://technet.microsoft.com/en-us/sysinternals/bb842062.aspxhttp://download.sysinternals.com/Files/PageDefrag.zipDEFRAGGLER: http://www.piriform.com/This way you would not have problem checking disk but weekly or twice a month.

What is the purpose of starting the first command in the file in a separate window (Start /wait CHKNTFS /d C:)?Why use multiple chkntfs commands when a single one can globally reset the default behaviour on all the drives?Why use the /v switch when running unattended chkdsk?Assuming that C: is the boot volume (the Windows drive) then the CHKDSK /f /v /r /x C: command will choke as it will go unanswered. Furthermore, your batch file has no command to restart the computer so the boot volume will go unchecked until a manual restart is initiated.Downloading large files will not fragment the MFT unless the disk is running out of space, in which case the file system will relent and yield space for the files within the MFT zone. A large file uses no more MFT space than a small file, each file uses one MFT record and information which cannot be stored in the MFT entry is store in an non-resident attribute (ouside the MFT).PageDefrag cannot defragment the MFT.For most users defragmenting and running chkdsk on a weekly basis is excessive and a complete waste of time.

If I only chkdsk D: drive, which is data drive, can I apply your coding for scheduling task?I only need to do it one per bi-month for checking disk for any error.Batch file #1, (Copy the stuff between the --- lines ---): -------------------chkdsk.bat-------------------------------echo y|chkdsk D: /Fschtasks /create /tn Hib /sc onstart /tr c:\hib.bat /ru ""shutdown -r -f -t 0------------------------------------------------------------ Batch file #2.

If you are only wanting to check the data drive and then hibernate the machine when done then the following single batch file will do it:-------------------chkDatVol.bat------------------chkdsk d: /f /xPowercfg /h onRUNDLL32.EXE PowrProf.dll,SetSuspendState-----------------------------------------------------The /X switch instructs chkdsk to dismount the volume if necessary.Do chkdsk /? at the command prompt for more help on chkdsk.The second Hib.bat file is only needed if you chkdsk the Windows drive, that is because the machinemust be restarted to run a boot time chkdsk on the boot volume, after chkdsk is done Windows starts normally, so you need an additional task to then hibernate the machine.John

[OS] The format for C: drive is NTSF, when I try to scan C: drive, it will only perform scanning when window restarts next time.[Data] The format for D: drive is NTSF, when I try to scan D: drive, it will only perform scanning when window restarts next time.[Data] I get another Z: drive is also NTSF, but when I try to scan Z: drive, it will perform scanning immediately without restarting window.It seems to me that Z: drive will work with chkDatVol.bat file, but D: drive will work with chkdsk.bat, because it requires restarting window, when I do it manually.I would try both files at this weekend to see how it works.Do you have any suggestions on why some data drive perform scanning immediately, but other requires to restart window to perform scanning?Thank everyone very much for any suggestions
