In an effort to support removable media devices in SyncXpress I’ve had to do a bit of learning about WMI in .NET. It is actually quite cool how much information you can get from WMI about ANY piece of hardware attached to your system, and even INSIDE your system. So in my case I want to find out information about a logical drive device in Windows. Using the System.Management namespace we can access the ManagementObject classes that will allow us to query the WMI services to get information about our device. Here is an example of getting information about your C:\ drive.

ManagementObject wmi;
string serialNumber, name, freeSpace;

wmi = new ManagementObject("Win32_LogicalDisk.DeviceID=\"C:\"");

serialNumber = wmi["VolumeSerialNumber"].ToString();
name = wmi["Name"].ToString();
freeSpace = wmi["FreeSpace"].ToString();

For more information on what data can be queried on a logical device see http://msdn2.microsoft.com/en-us/library/aa394173.aspx
