Abstract
Various embodiments of the present invention are directed to systems and methods for 'attaching' a virtual hard drive to the physical computer hardware by implementing a specialized disk controller driver for the host operating system that is recognized by the host operating system as a disk controller driver but which in fact also emulates the virtual hard disk it is 'attached' to. When the host operating system sends requests to read and write sectors from the virtual hard drive, the specialized driver (the “virtual hard drive controller driver”) directly accesses and manipulates the back-end file mentioned above. Thus the virtual disk is “attached” and recognizable by the host operating system and can be manipulated thereby (and applications executing thereon).
