Windows XP: chkntfs.exe uses 100% of cpu
chkntfs.exe uses 100% of cpu
by dreyescairo - 8/7/07 11:33 AMWhenever I start up my laptop I get a few moments before my computer begins to slow down significantly. My Sprint Broadband connection stops working and I can't get anything to work at normal speed. When I check the computer processes in Task Manager, I see that chkntfs.exe is running and has hogged between 90 and 100% of my CPU capacity. When I turn off the process, things generally go back to normal. Sometimes one of my svchost (system) iterations also begins to use large amounts of the CPU after I shut down chkntfs. Why is this process working this way, and how can I get it to run normally? I've run antivirus scans and adware scans and they don't help. I've had this machine over 2 years now and never had this problem before.

The DMA mode has fallen down to PIO. Read the next link -> http://winhlp.com/?q=node/10

Must be something else...

Thanks for your help. I tried the manual solution by running regedit but to no avail. After reboot I still had chkntfs running at above 90 percent of CPU load. Before I tried this I checked the device manager and everything was running in Ultra DMA mode, but I figured I'd try anyway. Haven't found any drives running in PIO. Any other suggestions?
Ok, any "extra" chkntfs.exe's ?

As far as I can tell I donīt have any extra instances of chkntfs running or existing on my drives. Iīd read that thread when I was doing my initial research on the issue. I also read somewhere that there is a malware program that uses a bogus version of the file name with some kind of hidden character to make the user think itīs a legit program. Any knowledge of how that might work or how to detect it?

According to this link.It is designed to disable the automatic running of chkdsk on specific volumes, when Windows restarts from an improper shutdown
Maybe for some reason chkdsk is trying to start.
Try chkdsk /f in the command prompt.LINK

chkdsk /f
by dreyescairo - 8/7/07 6:59 PM In reply to: dreyescairo by tomronI get this message:
The type of the file system is NTFS.
Cannot lock the current drive.
Chkdisk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)
What do you think?
No dice...
by dreyescairo - 8/9/07 12:20 AM In reply to: OK by tomronI've tried it, nothing seems to work so far. Is there a way to disable chkntfs.exe so it doesn't run on its own?
OK
by tomron - 8/9/07 1:23 AM In reply to: No dice... by dreyescairoSince your other scans found nothing doesn't mean that there is nothing there.
Check this link Infected With Chkntfs.exe.
You need to run hijack this but cnet doesn't analyze logs,this LINK has instructions.
