Enumerate Drives

Problem : You want to get a list of all drives installed on the system.

Solution: The DriveInfo class provides static methods to retrieve this information.

DriveInfo[] drives = DriveInfo.GetDrives();
foreach (DriveInfo info in drives)
{
    Console.WriteLine("Name: {0} (RootDirectory: {1}",
                      info.Name, info.RootDirectory);
    Console.WriteLine("DriveType: {0}", info.DriveType);
    Console.WriteLine("IsReady: {0}", info.IsReady);
    //you'll get an exception if you try to read some
    //info when the drive isn't ready
    if (info.IsReady)
    {
        Console.WriteLine("VolumeLabel: {0}", info.VolumeLabel);

        Console.WriteLine("DriveFormat: {0}", info.DriveFormat);
        Console.WriteLine("TotalSize: {0:N0}", info.TotalSize);
        Console.WriteLine("TotalFreeSpace: {0:N0}", info.TotalFreeSpace);
        Console.WriteLine("AvailableFreeSpace: {0:N0}",
                          info.AvailableFreeSpace);
    }

    Console.WriteLine();
}

This code produces the following output on my system (edited to show only unique drives):

Name: A:\ (RootDirectory: A:\)
DriveType: Removable
IsReady: False

Name: C:\ (RootDirectory: C:\)
DriveType: Fixed
IsReady: True
VolumeLabel:
DriveFormat: NTFS
TotalSize: 160,045,199,360
TotalFreeSpace: 81,141,878,784
AvailableFreeSpace: 81,141,878,784

Name: F:\ (RootDirectory: F:\)
DriveType: CDRom
IsReady: False

Name: H:\ (RootDirectory: H:\)
DriveType: Removable
IsReady: False
