Abstract
Systems, methods, and devices for nondestructive data transfer are disclosed. A method comprises monitoring commands directed to a storage device and evaluating the commands to determine whether the commands are harmful or benign. Benign commands are presented to the storage device. If a command is harmful to the contents of the storage medium, a replacement command is presented to the storage device, and a response expected from the storage device is emulated. A device implementing the method may include an intercept logic, a bridge unit and an isolate switch. In an embodiment of a system that implements the method, the device is coupled between a storage device and a computing device. The method may be implemented in software instructions stored on a machine readable medium and executed by a processor.
