    Abstract: PROBLEM TO BE SOLVED: To perform access not lowering a performance specialized in sequential media without executing mounting depending on a hardware device on an application side.SOLUTION: In a file system 60, a command processing part 61 takes out an option indicating a file listing method from a command, an index reception part 63 receives an index including a directory name, a file name and a recording position from a tape drive, and an index storage part 66 stores the index in the state as it is or in the state of changing the directory name or the file name according to the listing method indicated by the option. In the meantime, when an IRP reception part 67 receives an IRP (I/O Request Packet) from an OS, an IRP setting part 68 stores the file name inside the index in a buffer of the IRP in the order of the recording position, and a response transmission part 69 returns a status to the OS.

    Abstract: The invention provides a method that detects whether data on a tape drive used in a file system has been altered. The method contains: (a) a step that prepares a first tape cartridge provided with a tape in which multiple files and an index information history have been stored in a WORM partition, and index information has been stored in an R/W partition; (b) a step that reads and compares the R/W partition index information and the index information at the end of the WORM partition; and (c) a step that determines that the R/W partition index information has been altered if the R/W partition index information does not match the index information at the end of the WORM partition.

    Abstract: Die vorliegende Erfindung stellt ein Verfahren zum Erkennen bereit, ob Daten in einem Bandlaufwerk manipuliert worden sind, das in einem Dateisystem verwendet wird. Das Verfahren beinhaltet die Schritte: (a) Bereitlegen einer ersten Bandkassette, die ein Band enthält, auf dem in einer WORM-Partition mehrere Dateien und Archiv-Datensätze von Indexinformationen und in der R/W-Partition eine Indexinformation gespeichert sind; (b) Lesen und Vergleichen der Indexinformation der R/W-Partition und der neuesten Indexinformation der WORM-Partition miteinander; und (c) Feststellen, dass die Indexinformation der R/W-Partition manipuliert worden ist, wenn diese beiden einzelnen Indexinformationen nicht übereinstimmen.
