Free space disappearing slowly on DC

Hi all,

I have a Windows 2000 SP4 Domain Controller which went
live at the beginning of May 2004. It is running the
follwing apps/services:

- Exchange 2000 SP4
- Backup Exec 9.0
- Norton AV Corporate 8.1

We have two 36Gb drives in a RAID 1 configuration,
partitioned as 8Gb (C:) and 26Gb (D:). All data and
exchange server databases/logs are on D: drive. The page
file (fixed 1536Mb size) is on C: drive.

My problem is that the space on C: drive seems to decrease
by around 100Mb every month (around 25Mb per week). I have
been running treesize weekly on the drives since
installation to see where the space is going and Treesize
reports that disk space is always around 25Mb less than it
was the week before. However when analysing the size of
each folder individually I see that the only folders to
increase in size on a weekly basis are the WINNT\system32
folder, the BackupExec 'catalogs' folder and the Norton AV
folder. However these folders only go up by around 2Mb max
each so I am confused as to where the additional space is
being lost?

Some of the things I have done to try and find a solution
are:

1. Run a chkdsk with the /r and /f options in case Windows
is not reporting the file sizes correctly.

2. Run a defrag on the C: drive.

3. Checked the sizes of hidden files/folders (e.g. @System
Volume information' and 'C:\recycler' but the size of
these folders is literall 20Kb (the Recycle Bin is emptied
regularly!).

- Disabled Norton AV for a week to see if its Liveupdates
were causing the issue

All of the above options have not yielded a solution. I am
a bit worried that, at the current rate of consumption, we
will be out of space on C: in just over two years! We
started off with 3.5Gb free - now we have 3.2Gb free after
3 months.

Anyone have any suggestions? Treesize's number dont seem
to add up...

Many thaks in advance for any assistance.

Hi Josh,

The reason I am reply to your request is due to me seeing
a very similar problem. However my problem is a lot more
critical. The C: drive free space has dropped at quiet a
rate with tonight only having 11MB's, yes that megabytes,
of free space. Cannot determine where it is all going
to. I will watch this message in the hope someone will
have an answer. My server is a Small Business Server
running W2K on 3 x 36GB Raid configured drives in dynamic
configuration.

Regards,

Ken.

Blatant Plug: WatchDISK by PowerAdmin.com is what you need. It will
take a snapshot of your directory sizes, and then later when you want
to know where the disk space went it will take another snapshot and
very quickly show you where the space is being used. It has a 30 day
free trial which ought to help you solve your problem. Naturally it
has other features, but this seems to be what you need right now.

Hi DN,

Many thanks for that - I will give it a try and see what
happens. I am down to just over 3Gb on C: drive so I
really hope this solves the issue!

Josh.
