We got 2008 server running with 68GB D drive (Raid 1 with 72 GB & 142 GB) HDD's in PROLIANT DL 380 G5
Page file configured with 24 GB
Program files \ <Application> occupying 20 GB
apart from above we are unable to identify which folder is consuming remaining disk space
Tried using a tool called space monger(No luck) .Also tried with local admin account (Still No luck)
Ran Chkdisk in read only mode.Could message " Error Found run check disk in fix mode"
Please suggest is this is because of disk errors .
What tools can be used further and what else can be checked
Note : Checked with HP support regarding array configuration and been told that shouldn't be a concern.
