摘要： Volumes of a file system environment are taken offline when they require repair for confirmed corruptions. Applications utilize handles, both real and, in environments where proxy file systems are overlaid upon the real file system(s), proxy, to access objects stored on volumes of a file system environment. Real handles are closed when the volume storing the objects for the real handles is taken offline, terminating applications' access to the volume's objects. New real handles are automatically generated for those volume objects that had a real handle prior to the volume going offline for corruption correction processing and which were not altered during the corruption correction processing. Applications accessing these objects can continue to use their original proxy handle, which is subsequently correlated with an automatically established new real handle, to access the objects.
摘要翻译：文件系统环境的卷需要修复已确认的损坏时才能脱机。应用程序利用句柄，无论是真实还是在代理文件系统覆盖在真实文件系统（代理）上的环境中，以访问存储在文件系统环境卷上的对象。当存储实际句柄的对象的卷被脱机，终止应用程序对卷的对象的访问时，实际句柄关闭。对于那些在卷脱机之前具有真实句柄的卷对象，为了进行损坏纠正处理而自动生成新的实际句柄，并且在篡改校正处理期间没有更改。访问这些对象的应用程序可以继续使用其原始代理句柄，后者随后与自动建立的新的实际句柄相关联，以访问对象。

摘要： Perceived corruptions encountered on file system volumes, and which cannot be initially remedied online, are processed to verify whether they are true, existing volume data structure corruptions or, alternatively, false positives. Upon the verification of one or more of a volume's corruptions, error scanning is performed to check for, and attempt to remedy online, all the existing corruptions on the volume. Subsequent to error scanning processing, if one or more verified corruptions continue to exist on a file system volume, at file system boot up time spot corruption correction is performed to attempt to remedy the existing, verified corruptions on the volume. Spot corruption correction is performed to attempt to correct verified data structure corruptions on a volume of the file system while the volume is maintained offline for the time necessary to attempt to correct its prior identified corruptions.

摘要： An extensible file system format for portable storage media is provided. The extensible file system format includes the specification of primary and secondary directory entry types that may be custom defined. The primary and secondary directory entry types can be further classified as critical and benign directory entries.

摘要： A recording method of the present invention includes the steps of: receiving a write instruction which specifies at least a logical sector in which data is to be written; determining whether the logical sector specified by the write instruction corresponds to a recorded physical sector or an unrecorded physical sector (S1111); when it is determined that the logical sector specified by the write instruction corresponds to an unrecorded physical sector, writing the data into the unrecorded physical sector (S1112); and when it is determined that the logical sector specified by the write instruction corresponds to a recorded physical sector, writing the data into an unrecorded physical sector other than the recorded physical sector (S1113), generating a remapping table including remapping information which remaps an original address of the recorded physical sector to a remapping address of the selected physical sector, and writing the remapping table on the write-once disc (S1114).

摘要： Improved methods and systems for granular opportunistic locking mechanisms (oplocks) are provided for increasing file caching efficiency. Oplocks can be specified with a combination of three possible granular caching intentions: read, write, and/or handle. An oplock can be specified with an identifier that indicates a client/specific caller to avoid breaking the original oplock due to an incompatibility from other requests of the same client. An atomic oplock flag is added to create operations that allow callers to request an atomic open with an oplock with a given file.
摘要翻译：提供了改进的粒度机会锁定机制（oplock）的方法和系统，用于提高文件缓存效率。可以通过三种可能的粒度缓存意图的组合来指定Oplock：读取，写入和/或处理。可以使用指示客户端/特定呼叫者的标识符来指定oplock，以避免由于与同一客户端的其他请求的不兼容而破坏原始oplock。添加一个原子oplock标志来创建允许调用者使用给定文件的oplock请求原子打开的操作。

摘要： A file system is enabled to use a Metadata Partition instead of VAT for write-once discs, and is provided by a pseudo-overwrite method with a plurality of tracks especially for metadata and file data. On applying this invention to a drive apparatus that supports pseudo-overwrite media, the file system distinguishes data to overwrite from data to append (S1701). When the data is newly written to a logical sector, the drive apparatus writes the data to a physical sector to which the logical sector corresponds (S1703). When the data being overwritten is data stored in the logical sector, the data is written to the other unrecorded physical sector in the volume space (S1704), and remapping information is written (S1705). The remapping information specifies the original address of the physical sector, and the remapping address of the physical sector in which the data is written.
