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.

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. The directory entry types can define whether a cluster chain corresponding to a file can be contiguously allocated.

摘要: This document describes tools capable of enabling an entity requiring exclusive access to data and metadata of a volume to have that exclusive access while also permitting another entity to have access to data and metadata of that volume. The tools, for example, may permit a ChkDsk program to detect and correct data/metadata integrity errors while permitting users to maintain access to a live volume having that data and metadata. In one embodiment the tools create a copy of a logical volume, permit exclusive access to the copy while permitting access to the live volume, and, when the exclusive access is no longer needed, merge the copy and the live volume.

摘要: A method and system for computing disk space used by a directory and its descendants that may proceed while input and output are occurring that involve the directory and any of its descendants. A calculation of the total amount of disk space consumed by a set of objects is commenced. While performing the calculation, changes to the objects are monitored. If a change to one or more of the objects affects the disk space consumed by the objects, the calculation is changed so that the total reflects the change to the one or more objects.
