To open a physical hard drive for direct disk access (raw I/O) in a Win32-based application, use a device name of the form

\\.\PhysicalDriveN

where N is 0, 1, 2, and so forth, representing each of the physical drives in the system.

To open a logical drive, direct access is of the form

\\.\X: 

where X: is a hard-drive partition letter, floppy disk drive, or CD-ROM drive.
