HDD: Total capacity 500GB partitioned to C & D equally. O S: Windows Vista Home Prem. installed on C. Actual space on C: About 223GB. Space occupied : About 73GB. Free space on C: About 150GB. So shows the properties of the partition. Tried to make another partition out of the free space of C. After calculation, report showed only 66MB available. Astounded. Why only 66MB out of 150GB? One of the procedures of RSS installation is to format... Is the 66MB problem because of the installation of RSS? IF it is, how to resolve it, please?
