Our current invention is an improvement of our pending U.S. application Ser. No. 09/961417. As previously disclosed, the blocking device (203) provides read and write protection for computer long-term storage devices (205), such as hard drives. The blocking device is placed between a host computer (201) and the storage device (205). The blocking device (203) intercepts communications between the host (201) and the storage device (205) and examines any commands from the host to the storage device. Certain commands, such as commands that may modify the storage device, may be discarded. Our current invention improves Ser. No. 09/961417 by enabling multiple host computers (1011, 1012, 1013 . . . ) to communicate to the blocking device (203). Our current invention further improves Ser. No. 09/961417 by selectively blocking only specified host computers.
