14 Jun 1999TL;DR: In this article, a write protection method for protecting data recorded on a recordable and/or rewritable disc from unwanted overwriting or erasing is proposed, where the write protection information stored on a disc does not match the state of a recognition switch of a case for write protection.
Abstract: A recording medium storing a write protection information, and a write protection method for protecting data recorded on a recordable and/or rewritable disc from unwanted overwriting or erasing. In order for write protection of a disc in a bare state that is usually used in a cartridge having a recognition switch for write-protection, such as a DVD-RAM, write protection information is recorded in a Lead-in area, a Lead-out area or a recording information area other than a user data area of the disc, and the data is protected from unwanted overwriting or erasing using the write protection information. Also, even though the write protection information stored on a disc does not match the state of a recognition switch of a case for write-protection, the data can be prevented from unwanted overwriting or erasing. Thus, the write protection can be ensured when a recordable and/or rewritable recording medium, such as DVD-RAM, DVD-R and DVD-RW, is used in a bare state.

TL;DR: In this article, a workstation 12, acting as a remote management console, generates a wake-up packet 32 or 42 intended for a desktop computer 14 on the LAN 24, and a network interface 64 receives and processes the wakeup packet, and issues a signal to wake up the desktop computer.
Abstract: A method and related apparatus enables one station on a local area network (LAN) 24 to remotely and securely modify sensitive information of another station on the LAN 24. A workstation 12, acting as a remote management console, generates a wake-up packet 32 or 42 intended for a desktop computer 14 on the LAN 24. A network interface 64 receives and processes the wake-up packet, and issues a signal to wake up the desktop computer. In response to the signal, the desktop computer 14 bootstraps. Data indicating that the network interface 64 has issued the signal is stored in register 104. In the course of bootstrapping, the processor 78 examines the register 104 to determine that the network interface 64 has initiated the wake-up of the desktop computer 14. Once this determination is made, the write protection circuitry 76 places the BIOS ROM 74 in an unprotected state wherein the contents BIOS ROM 74 can be modified by the workstation 12.

TL;DR: In this article, a mass storage device protection system is described, where a processor is configured to generate at least one serial write command signal to the mass storage devices via a serial communication link.
Abstract: A mass storage device protection system may have a mass storage device, a processor configured to generate at least one serial write command signal to the mass storage device via a serial communication link, and a storage protector configured for communication with the processor and mass storage device, the storage protector configured to do the following: intercept the at least one serial write command signal, and determine whether the at least one serial write command signal comprises an authorized command signal or an unauthorized command signal.

TL;DR: A blocking device as mentioned in this paper intercepts communications between the host and the storage device and examines any commands from the host to the storage devices, such as commands that may modify the hard drive.
Abstract: A 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 (205) 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.

TL;DR: In this article, a write protection circuit and a write poster are described for a computer system including a write buffer and a cache invalidation mechanism. But the write buffer is not used for the execution of arbitrary operations.
Abstract: A computer system including a write protection circuit and a write poster is disclosed. The write protection circuit provides page description information to the computer system for controlling various operations. Illegal write operations as defined by the page description information are prevented from reaching a system bus and external cache. Internal cache invalidate operations may also be performed transparently to system operation. The write poster accepts write operations in zero wait states and assembles them into fewer more efficient writes to memory. A unique method and apparatus for programming a descriptor random access memory (RAM) is also provided.
