Segment Usage/Freespace by device.

I need the ability to monitor my segment usage by device in MB for data growth.  The scripts I have found/developed are not providing the information I need.   At a minim the devices are separated by data and index.  Would any one have a good script for this?

Example.

Database ScoobyDoo.

database_name database_size

------------- -------------

ScoobyDoo 284536.0 MB  

reserved           data                 index_size    unused    

------------           -----------           -----------          ----------
