View Full Version : Major chkdsk problems with WIN7

18-10-2011, 10:25 AM
I am installing WIN7 on an ACER machine that has am XP pro on one of the HDDs.

I have got through to and installed SP1 (not without problems) but each time I do a download of updates I have to complete a chkdsk /F on the Win7 drive. If I don't, Win7 doesn't go through to Microsoft's update department. This is becoming very frustrating!

Has anyone got a solution? When the chkdsk runs, sometimes many files are deleted and then recovered and then I can download again but then must run chkdsk /f again.

copied since I cant be bothered writing it all out :)

Click on Start, All Programs, Accessories. Right click on Command Prompt and select Run as Administrator

NOTE: the X in bold is the drive letter - So if the drive you want to check is C then the command will be chkntfs /x C:

Type fsutil dirty query x: This queries the drive, and more than likely it will tell you that it is dirty.

Next, type chkntfs /x x: 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 x: /f /r. Reply Y if asked if you want this to happen on the next boot. This should take you through 5 stages of the chkdsk scan on the next boot and will unset that dirty bit. Be patient as this can take an hour or more depending on the size of the hard drive or partition.

Once booted back to Windows, open another Command Prompt and query the dirty bit again by entering fsutil dirty query x: and Windows will confirm that the dirty bit is not set on that drive.

Thanks FT. However the damn installation has now had a hissy-fit. Blue screen saying PC has a problem and will shut-down so back to the drawing board to get the thing working. Will use your method soonest, thanks again.

run a chkdsk /R : to check for bad sectors.

perhaps ??
Download Win7 SP1 rather than trying to update to SP1 via MsUpdates (too painful)
Format the whole drive, clean install of Win 7('custom' option & delete all existing partitions)
