What is chkdsk /f.? Small happen when I try to defragment, how can I get rid of this?

When I'm trying to do a disk defragment, I get a message that /f chkdsc.  is planned.  I don't know what it is, how do I get rid of it or go around it, defragment my disk?   Thank you!

When you try to defragment a volume and Disk Defragmenter reports:

Disk Defragmenter has detected that Chkdsk is scheduled to run on the volume: (c :))
 
Please run Chkdsk /f.

This means that the volume that you want to defragment was marked 'dirty' XP.  This is not necessarily all of the data has been lost on the volume, it simply means that XP thinks that the volume should be checked to find errors because of something that happened before.

You won't be able to defragment the volume until the dirty bit has been removed.

This does not mean that a disk check is scheduled to run, and you can't cancel what needs to happen in this case because this isn't the problem.

Also the dirty bit is not set on a volume, you can still run a disk defrag with a record of date of arrival in the meantime (try).

Entry of commands to reset or erase a disc awaiting review is therefore a waste of time - that is not the problem.

A volume can be marked as dirty, if the system underwent a power interruption (power failure, pulling plug, removing the battery, button / stop), abandoned restart or an abnormal termination.  One of these events?

When XP starts, it automatically checks the bit of impurity on each volume.  You can also tell XP to ignore the bit of impurity on any volume, but this probably isn't a good idea in case there is a real problem that needs to be fixed.  If you have a hard drive where the dirty bit will not disappear, you can tell XP not to check.

If the starting XP detects that the volume is dirty, it will be automatically run the check disk with error correction (chkdsk/r) and try to fix the problems detected.

If the chkdsk command succeeds, it clears the dirty bit, and then you can defragment the volume.

You can check the status of your bit of impurity from a command prompt window.

To do this, click Start, run and enter in the box:

cmd

Click OK to open a command prompt window.

For example, to query the bit of impurity on drive C, type:

fsutil dirty query C:

The sample output:
Volume c is dirty
Volume C: is dirty

Is the volume of your sale or it is not dirty?

You cannot use fsutil or chkntfs from a command prompt to delete the bit of impurity on a volume.

The only thing that can clear the bit of impurity on a volume is chkdsk /r (or chkdsk/p).  You could tell XP not to check the bit of impurity on a volume where the dirty bit does not erase, but this probably isn't a good idea since there is some sort of problem on the volume.

You will be not also solve this problem by editing your registry database (pay attention technical support engineers and moderators of Forum)-is not the problem.

Once a volume is marked as dirty, the only way to clear the dirty bit is to run "chkdsk/r" or "chkdsk/p" when the volume is not in use.  The only way a volume can not be used while XP is just starting to load or from the XP Recovery Console.

If XP will not run chkdsk correctly when your system restarts or the dirty bit will not erase as it should, you need to look in the Event Viewer log chkdsk and see what is happening and fix it.

If XP will not always clear the dirty bit, you need to run chkdsk/r of the XP Recovery Console so you can look and see what works and run it again until it works.  If your hard drive fails, you may never be able to clear the dirty bit, in this case, you can also say XP never check the afflicted volume dirty bit.

Saying XP not to check the bit of impurity on a volume would be risky behavior because there would always be some kind of problem with your hard drive.

You can manually program the disk with error correction check to run at the next reboot of the system, but if the dirty bit has been set, XP should run check disk automatically with error correction during the next reboot.

This is usually the case that after a reboot, the problems will be resolved since XP will automatically run check disk on the Sales volumes when it restarts.  If you do not check that the chkdsk results of newspapers after his execution on a restart, you will never know what problems are corrected or remain.

When you choose to run the check disk with error correction in the Tools menu of disk properties, you will be prompted with a message similar to the following:

The disk check cannot be performed because the disk check utility needs exclusive access to some Windows files on the disk.
These files can be access only by restarting Windows.  You want to schedule the disk check to occur the next time that you restart Windows?

Answer Yes, if you want to schedule the check disk on the next reboot of Windows.

When you choose to run the check disk with error correction in the command prompt window, you will be prompted with a message similar to the following:

The type of the file system is NTFS.
Cannot lock the current drive.

Chkdsk cannot run because the volume is in use by another
process.  You want to schedule this volume to be
check the next time the system restarts? (Y/N)

Answer Yes, if you want to schedule the check disk on the next reboot of Windows.

When XP restarts, let the disc over to check and correct the problems, he could find.  Do not interrupt the disk check.  It can take a long time (hours or days) to complete or they seem to be "stuck".  Be patient.  If the HARD drive light flashes, it's something.  Keep an eye on the amount of the percentage to be sure that it is still making progress.  It may even seem to go back sometime.

If there is a problem with the chkdsk command that works on reboot and it doesn't really seem to do something (too fast) or not to clear the dirty bit (check the dirty bit again), the command chkdsk which took to restart results in the Event Viewer Application log.  Look there to see what happened.

When chkdsk runs automatically reboot, you may wonder where to find the results.  The results appear in the Event Viewer Application log.

You will need to get there after the disk check performed and XP has finished loading for the results and all the problems.

To view the logs in Event Viewer, click Start, settings, Control Panel, administrative tools, event viewer.

A shortcut to the event viewer is to click on start, run and enter in the box:

eventvwr.msc

Click OK to launch the event viewer.

Look in the Application log for a proposed Winlogon event, something like this successful race:

Event type: Information
Event source: Winlogon
Event category: no
Event ID: 1001
Description:

Checking file system on C:

The type of the file system is NTFS.

A disk check has been programmed.

Windows will now check the disk.
39070048 KB total disk space.
25151976 KB in 78653 files.
48256 KB in 10264 index.
0 KB in bad sectors.
237080 KB in use by the system.
65536 KB occupied by the log file.
13632736 KB available on disk.

Windows has finished checking your disk.

If you see errors - same errors that are corrected, you must run the disk checking with correction of error again (chkdsk/r) until you see no error.  You should have no errors.  Check again the dirty bit.

If the chkdsk command that runs on every reboot XP does not clear the dirty bit, you must run chkdsk/r from the XP Recovery Console and see if that will clear things upward.  It is a good idea because you can watch chkdsk as it works and see the results on your screen instead of looking in the event viewer connects or wondering what happened (she also just 'feels' better when we see that it works).

If you have no authentic XP bootable installation CD to boot into the XP Recovery Console, you can create a CD bootable XP (no XP media required) Recovery Console, and then run chkdsk /r manually.

Need instructions on how to create a CD of bootable XP Recovery Console to run chkdsk/r manually?
