free disc space vanishing on XP

  PeterSR 19:30 12 Jul 07

I have a problem with my PC running XP (SP2)

When I boot the PC, it shows I have 23GB (45%)
free space on my main partition (C:). As time
passes, this figure steadily drops until
eventually it shows 0MB free space. When I reboot
(doing nothing else), it returns to the original

Stopping all applications except disc manager to
display the Free Space and repeatedly selecting
"Rescan Disks" shows Free Space dropping by about
0.01GB each time.

I have run disc checks that never show any

This issue means that I have to reboot every few

Any suggestions?

Check whether you have this file:

I do not have a file C:\windows\system32\logfiles\wmi\trace

I was too quick. There is a file trace.log:

I had already tried turning of restore points.

The tracelog suggestion seems to have made some
difference. Now, repeated calls to Rescan Disks do
not nibble away at the free space. I'll have to
see what happens tomorrow to determine if the problem
has been resolved.

Thanks for you help.

Since making the tracelog change you suggested the problems has disappeared.

Thanks again
