Unable to run scandisk- Win XP Pro

By badair ·
I go to run scandisk, with fix errors box checked, & I get a msg that a process has access to the drive and that scandisk cannot fix errors. This didn't used to happen, wonder if the NAV product could be doing this? The system is: NEC GT100, 450mhz, 256Ram, XP Pro (upgrade from 98SE), trying to make a dinosaur live a little longer before extinction! How can I determine what may pgm or process has access to the drive, and safely stop that process from starting, so I can fix any errors on the drive? I believe that I have tried unchecking the fix errors box & running scandisk at startup, don't think that I was able to fix errors however. F1,F1!

Normal behavior for Checkdisk with both options checked, program says: "the disk check could not be performed because the disk check utility needs exclusive access to some windows files on the disk. The files can be accessed only by restarting windows. do you want to schedule this disk check to occur the next time you restart your computer?"
So you say yes and the reboot. The disk check operation runs before windows loads.
Now if yours says something else then you had better purchase a new hard drive soon.

If you only have one HDD in the machine the above is correct that is what should be happening as Scadisk will only run when Windows isn't.

When it does run it automatically fixes errors that have been made to the HDD if it isn't then try running a Disk Checking Utility from the Drive maker to check the HDD is still all right and not on its way out.

At one place where I did some work they had a computer on a desk that wobbled and it was causing the heads to contact the platters when they ran a BJ printer. They wouldn't listen until the drive died and then they bought a new desk and HDD. No problem since.

chkdsk /x /f ... /x forces dismount of the volume /f fixes errors. may want you to reboot for complete access to the volume.

Windows XP doesn't have ScanDisk !! However, it does have CHKDSK, which is similar. Unfortunately, the interface of Chkdsk is very limited - you only see a progress bar and not what is going on until the end, where you receive a limited report with the Command Prompt Chkdsk - and no report with the Windows-based Chkdsk.

NOTE: as far as Chkdsk is concerned - the boot partition will always be locked and chkdsk can only make repairs upon reboot !!

you can run Chkdsk to simply "check" the partition
you cannot run Chkdsk "directly" with "fix errors" enabled. However, if you try to run it with "fix errors" on the boot partition, the system will give you the option to run Chkdsk upon the next reboot and then it will run and fix any errors. You can run Chkdsk with "fix errors" enabled for any non-bootable partition and it will run without having to reboot !!

Chkdsk from the Command Prompt

Start/Run . . . cmd
chkdsk x: /f - where "x" is the drive letter, and "/f" (fix errors) is optional

Chkdsk within Windows

NOTE: Scandisk is not the same as Chkdsk, although functionally they do the same thing !!! Chkdsk will only run during bootup, and will only run if the system detects a cold boot or power off.

1) double-click My Computer
2) right-click on the drive you want to run scandisk on
3) click the Tools tab and click "Check Now" next to "Error Checking"
4) to fix errors, check the "Automatically fix file system errors" box - and
to run a surface scan, check the "Scan for and attempt recovery of bad sectors" box
5) If the drive is the boot drive, reboot and Chkdsk will run during the boot process before Windows starts. If the drive is not the boot drive, Chkdsk will run without rebooting.

dmiles is correct, in XP, it is chkdsk, I did tell it to run during boot up, but the system did not reboot on its own. I got a failure msg. because apparently it was looking to boot from the CD/ROM drive, & told me to insert the startup disk, so I shoved in the Win XP upgrade disk (all I had, as this O/S is an upgrade from 98SE) & after it copied a bunch of installation files, I responded for it to do a Recovery of installed windows, the system then displayed C:\Windows & sat there, didn't do squat, so I entered "Exit" to get out & restart PC, then it rebooted off of the upgrade CD OK & ran the chk disk, no errors were found, I then took out CD & rebooted, weird, but it ran. Next time I think I'll just shut the old boat anchor down rather than a warm boot.

You should try Spinrite, it checks&fixes hd errors from a dos floppy, w/o interference from the os.
