I have a 2004 Dimension 8400 (with a specific service tag) that will only
defrag to 51% and then blue screen. I received this error message (which is
basically a bunch of hex numbers) and I can’t find a way to fix it.
In this excerpt from

Blue screen on defrag
If defragging your machine causes it to blue screen at some point, I believe
that usually indicates that there’s a physical problem with your hard
You should start by running Chkdsk (CHKDSK /R actually) to test the entire
surface of the hard disk.
Let me back up… what you really want to start with is a backup! You want
to backup that hard disk because clearly you are at risk of losing what’s on
that hard disk.
But after you’ve backed up, then make sure to run CHKDSK /R on it to
basically check the surface for errors and potentially work around any of the
errors that it finds. It may work around some; it may not be able to.
That’s when a utility like SpinRite comes in handy. SpinRite can actually resolve many
errors, hard disk errors, at the physical level, at the magnetic media
Replace the drive
If that doesn’t do it (and you know in all honesty even it does!), if you’re
able to take a full backup of your machine, I’d really, really be tempted to
simply replace the drive.
The drives aren’t that terribly expensive. I would, like I said, after
you’ve backed it up (you’ve got everything on a backup image somewhere),
replace the hard drive, restore the image, and my guess is you won’t have a
But the big risk here is, I believe, that this kind of a blue screen when
you’re defragging really does indicate a problem with the hard disk. I would

case, I’d rather err on the side of safety and not lose any data.
So, be sure to back up and basically consider replacing the
