Cannot defrag C: drive....

[geronimo]

Its WinXP SP2. There is a very high amount of fragmentation on C:
drive. When I try to defrag with Windows defragger or a third party
defragger, it says that it cannot, as there errors on the drive. It
says that a scan is scheduled for the next time Windows reboots.
However, when I reboot Windows, scandisk does NOT run.
So I tried to go into safe mode to command prompt and manually run
scandisk. Well, I can no longer get into safe mode! The system files
load normally until it loads MUP.SYS. Then the message "press escape
to cancel loading D347BUS.SYS" pops up. Whether or not I press escape,
it never goes any farther in loading process. The hard drive light
just flashes almost continuous without ever going on. MUP.SYS is as
far as it goes. I also tried selecting safe mode rather than safe
mode w/command prompt, but that gives the same results. Next I tried
booting up from the XP CDROM into repair console. I think this should
have taken it to a command prompt. Went OK until it asked which OS I
wanted to boot (there was only one listed)--- and when I pressed
enter, it immediately rebooted the PC.
Until I can get into a DOS mode outside of Windows, I will not be
able to repair the errors on the C: partition. Am out of ideas.
Is the only solution a repair-install of Windows? Geronimo

Windows XP doesn't have Scandisk - that's why it doesn't run it.

DOS mode will do you no good whatsoever if it's a NTFS drive.

Boot into Windows. Run chkdsk on the drive. Failing that, it's a repair
install BUT the big question I'd be asking is what caused the errors in
the first place?

Start - run - scandisk
'Thorough' will take SOME time
Defrag from safe mode and see if the same error occurs

Before you do anything else, the first thing you do is make sure you
have copies of any important files from your hard drive.

Good luck.

Try booting to safe mode command prompt then run chkdsk /F

You should've been able to run chkdsk /F from the repair console. Not
sure why your system rebooted when you entered 1 for your operating
system. Try again.

Mup.sys is almost always the last thing you see when you're stuck in safe
mode but it's the next module being loaded that's a problem. You
could review system events for clues about which modules are causing the
problems. I rename problem modules D347BUS.SYS -> ORIGD347BUS.SYS to
temporarily get pass some problems.

FWIW, D347BUS.SYS is a Daemon Tools module that causes havoc on some XP
systems. Some people say it's not a problem others say it is a problem.
I'm with the latter since it cause DVD access issues on my system.

To be safe you should run a registry cleaner also System Mechanic is a
decent general purpose tool but there are some trial versions of registry
cleaners that might work.

A repair install may or may not solve the problem. You may be facing a
reformatting and fresh installation of the OS.

 

[geronimo]

I tried uninstalling Daemon Tools, since this(so I thought) was
making the safe mode boot pause (with option to bypass) D347BUS.SYS,
and maybe causing it to fail. However after unistalling it, I tried
safe mode boot again, but it made no change. Still pops up with query
as to whether you want to load this file or not, and it never gets
past MUP.SYS whether you press escape to bypass or not. Maybe I need
to try removing my capture card and other hardware? As long as the PC
still runs in normal mode OK, I am sure not going to risk a repair
install!
Maybe some other boot disk I could get would get it to boot up
sucessfully into safe mode? Right now all I have for bootable disk is
Windows XP disk.

any integrated peripherals? if so disable them

Did you search for the DBUS347.SYS and rename it?
Have you scheduled chkdsk /F for the next reboot?
Has system events shown a what errors occurred when you tried to
defrag?

 

[geronimo]

1) that is a great idea, will try to eliminate it that way.
2) Whether you run CHKDSK from the cmd line within (normal mode)
Windows, or you try to scan C for errors via Property/Tools menu
within Explorer, you get same results. It says it cannot scan the C:
drive, it is in use, not locked, would you like to schedule a scan on
next reboot? I always opt to do so. But never on reboot does it carry
out the disk scan!
3) No error event is occurring, nothing for Windows to log.

I found a website with free boot disk for NTFS file system/Win XP
PCs. I will try booting up the PC with this, and hopefully since
Windows will not even be running, I can then get chkdsk or whatever
error-checking utility it has to scan and fix the errors. (Then just
hope that Windows still runs!) Plan to make a full backup of C:
using Acronis before doing this.
