System and method for metadata modification

摘要

The present invention provides a method for modifying a first storage medium having a plurality of files, the method including providing a first modification tool; operatively coupling the first storage medium to the modification tool, wherein the operatively coupling includes bypassing a first operating system used to access the plurality of files; and dematerializing, using the first modification tool, at least a first file to form one or more dematerialized files. In some embodiments, the present invention provides a modification system for modifying a first storage medium having a plurality of files, the system including a first modification tool that includes an attachment module configured to operatively couple the modification tool to the first storage medium such that a first operating system used to access the plurality of files is bypassed; and a dematerialization module configured to dematerialize at least a first file to form one or more dematerialized files.

1. A method for modifying a first storage medium having a plurality of files including a first file that includes a plurality of data blocks, wherein the first storage medium includes a first metadata structure that describes the plurality of files, the method comprising:
providing a first modification tool; operatively coupling the first storage medium to the modification tool, wherein the operatively coupling includes bypassing a file-system component of a first operating system used to manipulate the plurality of files; constructing a second metadata structure that describes the plurality of files; and dematerializing, using the first modification tool, at least the first file to form one or more dematerialized files, wherein the dematerializing of the at least first file includes:
rendering the first file inaccessible without destroying the plurality of data blocks of the first file and without releasing the plurality of data blocks of the first file for reallocation.
