GetDiskData

 GetDiskData is a sample application that shows how to retrieve the main disk data

Remarks

1. Getting Data from the different drives of a machine could take a long time according to the current status of the drives:
it does not change a lot wheter or not the floppies are ready in floppy drive
the same is True for CD-Rom
however, it could take a while if network disks are unconnected before the OS give up and considered them as not ready.
2. Some functions of Windows are not able to handle disk larger than 2GB. Trying to get informations about large disk returns invalid data. In those cases, the capacity and free space are set as '>= 2GB'.
