When trying to run a boot-time defrag, using Diskeeper 9, it fails and
displays


"Couldn't open NTFS volume; Most likely cause: couldn't get exclusive access

Diskeeper boot-time defrag cannot occur safely when another process is
accessing the volume, so boot-time job requested will not run.
Try again later.

.........
.........
.........

Failed to initialize for volume C: -- volume probably not mounted or is not
NTFS
Exiting"

Can anyone help me resolve this?

Restart your computer and it should work.

You perhaps have Norton GoBack or similar software installed?

PS. I am running Windows XP Home and my drive file system is NTFS.

PS. I am running Windows XP Home and my drive file system is NTFS.

Sorry but I didn't say that the message that I get happens when I restart,
at which time the boot-time defrag should run.

No I don't have Norton GoBack installed.

WHY? That may be the problem. Turn off that option and run it when you
want, AFTER the system has had a complete chance to settle down (and
nothing is accessing the disk, like a few of minutes after bootup).

Maybe Zone Alarm. You have some software installed that is causing it.

Thanks for your reply.

The Boot-time defrag is designed to run at bootup to defrag things that
can't be defragged while online. Such things as the MFT and the Paging file
are not defragged while the system is in its normal state. They can only be
done when the drive is inactive i.e. at bootup before windows etc is
running.

But I have now tried it after a full Shutdown rather than a Restart with the
same result.

Many thanks for your reply.
I do have ZA installed and have updated it to the latest build but the
problem remains. I did think of uninstalling it to see if the Boot-time
defrag will then work. Do you think that is a good idea?
