Windows 7 and chkdsk on boot
It appears that the CHKDSK wants to run almost every time I reboot my computers with Windows 7. It happens on desktops and laptops as well. Any help? Udi Burg www.unisfair.com

You could well be experiencing a 'drive consistency' problem. If so, then I'm afraid the best course of action is to first completely wipe the drive and start over. Delete all partitions and then create new ones and start over with a fresh install. If the problems still continue then it's best to replace the drive.Manufacturer diagnostic tools are also useful to run a better 'check' on the drive than Windows provides.If the behaviour is indeed happening as I've described here then it's happening because Windows is perceiving the drive as having bad sectors. Those may or may not be genuine. In some circumstances a corrupted install can cause Windows to perceive a reliable drive as 'bad'. It's best to thoroughly check before assuming that the drive actually is an unreliable one.

This sometimes worked on XP and should also work on Vista or Windows 7. Click on Start then Run , type cmd and press Enter . Next type fsutil dirty query x: where x: is your boot drive. This queries the drive, and more than likely it will tell you that it is dirty. Next, type chkntfs /x c: . The X tells Windows to NOT check that particular drive on the next reboot. Now manually reboot your computer, it should not do a chkdsk and should take you directly to normal Windows login. Once Windows has fully loaded, bring up another Command Prompt and enter chkdsk c: /r . Reply Y when asked if you want this to happen on the next boot. This should take you through 5 stages of the chkdsk scan and will unset that dirty bit. This can take an hour or more depending on the size of your hard drive, be patient and let it complete. Once booted back to Windows, open another Command Prompt and query the dirty bit again by entering fsutil dirty query c: and Windows will confirm that the dirty bit is not set on that drive.

Steps provided by Ztruker is worth to have a test. Before that, we can first test to run a Check Disk in Safe Mode. After that, reboot the computer to see if issue still exists.

Udi Burg www.unisfair.com I have a similar issue but it happens after Event Error ID 55 is logged (NTFS). Can you check your logs and see if you have this ominouserror occur as well?My subesquent CHKDSKfinds no! erros(s).

How do you run a CHKDSK in Safe mode? You invoke a chkdsk c: (Systemdrive) which runs before Win starts on it. I fail to understand this suggestion.

get into Safe Mode, input CMD in Search, run it as Administrator. Type: CHKDSK C: /f /r

get into Safe Mode, input CMD in Search, run it as Administrator. Type: CHKDSK C: /f /r I still don't get this hocus pocus: It will still only execute CHKDSK C: /f /r on reboot/restart the same.

This issue can be caused by the same problem as described in the http://tinyurl.com/w7corrupt post. The program in that post clearly reproduces this issue without causing real disk problems.

I followed all your instructions carefully. It took me more than one hour to complete (with a hard drive of 220 GB) and my problem is solved! Thank you a lot!!!

This worked for me on a Win 7 machine - thanks :)

Ztruker I am a relative novice with Windows 7 and have just experienced this problem, but when I run cmd and fsutil dirty query x: I get a message saying I need administrator privileges. Can you tell me how I can make that happen either before I enter the cmd prompt or after? Sorry to be dense

I'm having the same problem with an Asus netbook running Windows seven, however, when I run the dirty query, I'm told that c: is NOT dirty. Chkdsk doesn't run on every boot, but often enough for it to be really annoying. Every time I let it run the check, no errors are found.

Thanks Ztruker... worked like a charm for my win 7 - 64 bit installation!

Hi alittleoldman, If you click start then type cmd in the search box. Wait for cmd to appear under "Programs" and right click the icon, selecting "Run as administrator" Best, Randall Kent | The Sevaa Group | www.sevaa.com

I have recently enlarged my system partition to fill out the entire drive. Since then I have had the same problem, no errors, but still chkdsk on most boots.

Sorry to be dense You will need to go to C:\WINDOWS\System32 and then, right click on CMD.exe and hit: Run as administrator. This will do the trick.

Above from Experts Exchange Hi, I have the same issue as described below but my issue is a little more weirdo than that! I just imaged my HP Z200 with Windows 7 Pro x64. It's a brand new HDD also (500go Seagate) and as soon as I'm finished imaging my HP, I can log in the computer, join it to the domain... etc! I reboot it on first time, chkdsk starts on startup for no reason! Then, it's doing its stuff and then reboot. At reboot, it loops on startup repair for ever and I can't do anything. I tried Bootrec.exe /all_switches_without_luck! I've done some changes to my PC to check for any hardware problem. - I changed the HDD (Samsung 500go for a Seagate 500go) - No luck - Swapped the Video card (nVidia Quadro 580FX for a Radeon EAH4350) I suspect the mobo to be in problem, maybe the HDD controller... Is anybody have seen this before? Thanks so much! David.

I used the first solution and it worked, but now I get BSODs that restart my computer. They have happened when I press the back button in my browser, when I link two items together in Yahoo Pipes, or when I'm away from the computer entirely. Should I try resetting the dirty bit? How would I do that?

After having done all of that, including doing plain old chkdsk c: on safe mode, it continues to send me to the same error screen, insisting that I do a system restore because there is a recently installed program preventing my chkdsk. Thing is, I can't do a system restore because it won't let me do that either. I can't format it either. It allows me to do all the preliminaries, but it won't erase the HP drive completely as when I reboot, I return to my system as if none of my formatting had taken place. Also, I've run the Malwarebytes, but that yields nothing and two other spyware programs won't update their files to the computer either. All of this seemed to take place when I downloaded Firefox a few months ago. I didn't really notice it much until i wanted to download Skype, which download works, only I can't communicate from the platform to the network on the computer when I enter my password. So, I'm thinking that these communications problems and my problems logging on with software based on my computer, or receiving updates for my windows and firefox are all related. Please advise.

Umm... As I read it, doing the chkntfs /x c: disables chkdsk from *ever* running again at boot. Is this wise? Keith De La Rue

Sorry for my bad english, its not my first language anyway. I have the same problem, everytime i reboot CHKDSK appears. I was reading your comment above really carefully, followed it step by step, CHKDSK is no longer there on the reboot but when i get to the stage where you said to bring up another Command Prompt and enter chdsk c: /r as soon as i press enter on the cmd window its says that the drive cannot be locker or something i cant remember and then i have a blue screen saying that the computer crashed then its loading some files and reboot its self and then it will ask me if i want to run it on safemode or normally. Just bought my gaming rig 2 months ago and i had to took it back twice already because it was crashed almost everytime after that CHKDSK. I do not understand what could be the problem and the other thing is that my computer freezes for like 30 seconds in every 10 minutes. I was thinking about to buy another hard drive but if i can fix it by this way i would not waste any money. Im really hoping that you can give me some advice. By the way i have Windows 7 Professional which was installed after they fixed my computer. Thank You

For almost a year I suffered from this problem. Included was Event Error ID 55 is logged (NTFS) in the event logs. On occasion, a day pass without the event. Typically there would be multiple entries on a single day. I was confident it was not a bad drive because it was new. I attributed my problem from using EASEUS Disk Copy to migrate to a larger disk drive. I was beginning to loose the faith in Windows 7 I followed the steps as outlined - CMD , run it as Administrator. Type: CHKDSK C: /f /r Reboot and let it complete. I did this several times but it did not resolve the problem. Last week I found this forum. I then decided to try it in "safe mode" - nothing to loose right ?!?! The computer started in safe mode, It appeared to stop loading the necessary files for safe mode, but I could hear the disk drive working. Kinda funny, it even stopped displaying the sys drivers on MUP.SYS. To my astonishment, the computer had restarted in normal mode, and since I have not had the problem re-occur. It may be my hopeful attitude, but the computer seems to boot much faster now ! I don't know what happened, but I do know the problem has ceased. I Agree with WIN7INE whats safe mode got to do with it when chkdsk is executing before windows starts. I have to give a thanks to the suggestion in safe mode.

There is no Run to click on Windows 7 start menu, that I can see. I can type run into search, then click run, then type cmd and press enter. fsutil dirty query x: requires system administrator access. It's my pc, I am prompted and can give get access with other commands like chkdsk/f but not with this one. Why am I typing chkntfs /x c: next and go through another reboot, if I'm just going to bring up another Command Prompt and enter chkdsk c: /r ? Not very good instructions for this windows 7 user. =(

Hi guys If you have problem using chkdsk why not try and download a hard drive utility specific to your drive direct from the drive maker like ( SeaTools for Windows ) or maxblast for maxtor, these utilities sometimes work when windows crap doesn't im actually doing one now and windows wouldn't do it plus it takes the pain out of trying to direct chkdsk to the drive you wanna do as im sure your aware. these are worth a try that is providing you have a os up and running, that is!. regards CS

RickeyV, I don't know if you have looked under "Start > All Programs > Accessories>" but under here you will find the CMD.exe, you can Right Click on this and select "Run As Administrator" then the commands work =) -LMAOIMH

I am having the same issue with the chkdsk problem; however, mine is a little bit different. I cannot get into my Windows at all and cannot get into Safe Mode to attempt to follow the instructions to fix it. Even if I hit a key to cancel the chkdsk, I keep looping around. It does ask me if I want Windows 7 or a previous version (XP) and I choose Windows 7...I shouldn't even have the option as my previous version of XP became corrupted through some viruses and someone installed Windows 7 instead. I had a bunch of errors about some files in Windows 7 and then when I started up the next time, this is all happening!!! I'm stuck and cannot get on my laptop (work computer) at all right now.
