Okay I am losing it-
C:\ drive on my Windows 2003 Server is partioned to 8.5GB with approx 8.15GB
usable disk space, This server runs just about every application Exchange
2003, SQL2000, Veritas 9.0, IIS program files and data files are installed
on the D:\ drive of the server.

When I highlight all the folders and files located on the C:\ drive the OS
calculates it to be under 4GB, however when I look at Free space I only see
649MB !! When the entire drive is 8.5GB

The pagesys file resides on the D:\ drive. Folders are setup to view all
files including system and hidden files. I have used just about every third
party application to view the directory size I cant seem to find where the
other 3.5GB is hidden

Any comments/suggestions greatly appriciated-

Consider that every file and directory listing (no matter what size) takes
up at least one cluster. Slack space is the area between the end of the file
and the end of the cluster. It can be calculated roughly by taking 1/2 of
the drive's allocation unit (cluster size) times the number of files, this
is the average wasted space. If you have a lot of small files then the
wasted space figure could be larger.

From a command prompt at the root of the drive in question;
chkdsk
to find out your cluster size (allocation unit)

Do you have explorer set to show hidden and system files? If not, you're
not getting an accurate reading of the file system size.

One thing you might want to do is get a copy of TreeSizePro from JAM
software - it may help you find what you're looking for. They have an eval
on their website - google it.

Hi you say you are running exchange do you have a policy that retains
all old email for atleast 60days? What about deleted mailboxes are those
deleted as soon as you remove them or do you have a policy to retain
mailboxes as well, I remember reading that if these policies are
impletemented then the disk space size is not represented properly.


hth,
