I was working with a client recently who needed a quick report to provide free disk space information for all of their Unix/Linux systems. I ran across this link and was really impressed with the report that they had put together as it provided information for the Unix/Linux drives and a very readable format: http://www.scomgod.com/?p=42. I was however really positively surprised to find that this same report also works for windows computers (see the graphic below for an example).
As a note, I did have to point the report to the existing data warehouse as shown below for the data source in reporting services.
The actual report can be downloaded from: http://www.scomgod.com/wp-content/uploads/2012/11/LogicalDrives.FreeSpace.Report.zip
