how to findout which drive is a cool disk?

[Fred 34]

Is there any function to return the kind of drive?

Hi, I know three ways to get some information on physical devices: 1. using the DriveInfo class 2. using WMI, have a look at the WMI classes Win32_DiskDrive, Win32_LogicalDiskToPartition, Win32_PhysicalMedia, Win32_CDROMDrive; which ones you want depends on the information you need. warning: not everything may be available to regular users under Vista/Win7 without going trough the UAC dialog. 3. using Win32 functions (from kernel32.dll), which requires P/Invoke. Here is an example prototype:

	/// /// Gets the drive type
	/// 
	/// drive name (letter colon backslash)
	/// /// 0 (DRIVE\_UNKNOWN) The drive type cannot be determined. 
	/// 1 (DRIVE\_NO\_ROOT\_DIR) The root path is invalid. (no volume is mounted at the path). 
	/// 2 (DRIVE\_REMOVABLE) The disk can be removed from the drive. 
	/// 3 (DRIVE\_FIXED) The disk cannot be removed from the drive. 
	/// 4 (DRIVE\_REMOTE) The drive is a remote (network) drive. 
	/// 5 (DRIVE\_CDROM) The drive is a CD-ROM drive. 
	/// 6 (DRIVE\_RAMDISK) The drive is a RAM disk. 
	/// 
	\[DllImport("kernel32.dll")\]
	public static extern int GetDriveType(string rootPathName);

For each of these, I refer to the MSDN documentation, Google, and some experimentation. :)
