Hi, I need your help.
I'm just newbie in using Conquest Dicom Server,
And for now, i have a problem with my storage, i think the partition get something wrong.
i just use 250GB harddrive with 2 partition. The first partition (C) is use for Windows system and it works normall.
The second partition (D) use for storage dicom image.
But now, i will add new 500GB harddrive, and make it for default storage for dicom images.
Can you help me to configure it, so all dicom images will be store in new harddrive.
Below it my dicom.ini config :

# This file contains configuration information for the DICOM server
# Do not edit unless you know what you are doing
