Disk Defrag won't complete even in Safe Mode...

Even in safe mode, when I try to defrag a volume which needs it very badly, I get an error to the effect of:

"Volume D has 39% free space but only 1% is available to disk defragmenter. 15% of free space is required..."

How can I ensure that disk defragmenter gets use of the disk space it needs?

You must move enough data off the box to another drive or machine so that you have at least 15% free space.

Try conpressing some of your files temporaily to free up enough space

Also, delete all files in your Temp folder, and clean out your Recycle Bin....

Start > Run > %temp% (OK)  then delete everything you find in there...  (If you have more than one profile on that system, then you will need to do this for each profile..)

Check Your Desk

right-click your system drive > Properties > tools Tab
Check Now > mark the 2 options then restart the machine

You can defrage now

JamesDS, there's plenty of space... I just can't seem to give it to disk defragmenter. I have already don eldardery's checkdsk but that didn't help. I have tons of room, but disk defragmenter just can't seem to use it! Even in Safe Mode! Help!

It sounds like you may have a little corruption of the MFT (Master File Table, what used to be the FAT)

Try running a scand disk or CHKDSK /f before trying the defrag again.

Also you will get this error sometimes if you have one or more files that are bigger on their own than the amount of space you have free.

Cheers

What's the difference between scandisk and chkdsk? This is a win2000 server, and I already did what eldardery suggested before.

sorry, my mistake, they are the same thing.

Have you tried moving the largest data files elsewhere?

Have you tried to run the defragmenter with the command line only, instead of using the GUI?  Use it with the -f switch to force defragmentation...

Usage:
defrag <volume> [-a] [-f] [-v] [-?]
  volume  drive letter or mount point (d: or d:\vol\mountpoint)
  -a      Analyze only
  -f      Force defragmentation even if free space is low
  -v      Verbose output

Make sure you don't have a command line anti-virus running. It will reset the defrag and it will continue to run but never complete.

Good Luck,

Here are the rest of the symptoms on this nearly dead machine:

1. It takes about 15 minutes to boot all the way into windows.
2. It won't defrag... but it's very fragmented.
3. explorer.exe sometimes takes all the CPU but it's sporadic
4. MS Exchange shows up twice in the Add/Remove Programs window
5. The BadMail folder is huge, and I can't delete its contents
6. The Start Menu hangs
7. MS Exchange backup fails
8. Data backup takes way longer than it should.

Try using the Recovery Console to delete that BadMail folder..  You must configure the SET command to allow access to the directory though (I believe)..  Note the following:

Before you can change any of the environment variables to TRUE, you must enable the set command option using one of the following Windows security tools:
The Security Configuration and Analysis snap-in in Microsoft Management Console (MMC)
The Domain Controller Security Policy in Administrative Tools.
The Domain Security Policy in Administrative Tools.
The Local Security Policy in Administrative Tools.
