    摘要: A partition manager enables the dynamic creation, reconfiguration, and deletion of logical volumes as non-removable storage devices are connected, reconfigured, or disconnected in a computer system by assigning partitions on a connected device to volume managers which create the logical volumes, and by removing the assignment when the device is disconnected or reconfigured. The partition manager receives notification from the operating system of the arrival of new volume managers in a system. When new partitions are created on a non-removable storage device in the system by a device driver, the partition manager intercepts the partitions before they can be registered with the operating system. The partition manager queries each volume manager, in order of their arrival in the system, as to whether the volume manager handles a particular new partition and assigns control of the partition to the appropriate volume manager. The partition manager associates the partition with the appropriate volume manager in an in-memory partition manager database. The partition manager also removes a partition from the control of the associated volume manager and disassociates the partition from the volume manager when the partition is inaccessible.

    摘要: A method and system for avoiding the overwriting of drivers by subsequent versions or other commonly named drivers includes generating a unique identity for every eligible driver package. Driver files from the driver package, or the entire driver package itself, are then installed in a subdirectory location in a common storage based on the unique identity. The driver files may be loaded to a memory from the subdirectory location. Thus, multiple driver packages and driver files having the same name may be installed and loaded side-by-side.

    摘要: A method and system that protects selected system and other files, by preventing changes to those files. In an asynchronous alternative, the change is prevented by copying back the original file when a protected file is changed, as known via an asynchronous notification. In an alternative synchronous embodiment, the change to the file is prevented from occurring. In the asynchronous notification alternative, a directory change notification notifies a file protection service whenever a file that has possibly changed is closed, providing the file identity as part of the notification. The file protection service determines from the file identify whether the file has been deemed protected. If protected, the file protection service prevents any actual change by verifying whether the protected file changed, such as by analyzing the file's contents against known valid contents. If not valid, the file protection service restores a saved copy that is itself verified.

    摘要翻译: 通过防止对这些文件的更改来保护所选系统和其他文件的方法和系统。 在异步替代方案中,通过在受保护文件更改时复制原始文件(通过异步通知已知)来防止更改。 在替代的同步实施例中,防止发生对文件的改变。 在异步通知备选方案中,每当关闭可能更改的文件时,目录更改通知通知文件保护服务,提供文件身份作为通知的一部分。 文件保护服务从文件确定文件是否被视为受保护。 如果受保护,文件保护服务可以通过验证受保护的文件是否已更改来防止任何实际的更改,例如通过根据已知的有效内容分析文件的内容。 如果无效,则文件保护服务将恢复已自身验证的已保存副本。
