This script will provide information on the drive capacities, in the form of total volume, used space, free space and then a percentage of used space.
Assuming that it is being executed on Windows Server 2003+ and the user calling it has permissions to run xp_cmdshell it should run without a problem
The script uses a built in tool present in Windows Server 2003 onwards, however this utility can be downloaded and deployed on other Windows Server operating systems. (Such as Windows Server 2000)
Hope you guys find it usefull!
