1. A method for preventing user-inaccessibility to application data and operating system data stored in a non-volatile storage device within a computer system resulting from corruption of said operating system data, said method comprising the steps of:

  • partitioning said non-volatile storage device into a first partition that stores application data and operating system data within at least one sector, wherein said operating system data includes filing level instructions for managing said application data and operating system data within said first partition;

    partitioning said non-volatile storage device into a second partition that is transparent to said filing level instructions, wherein said second partition includes at least one sector corresponding to each of said at least one sector included within said first partition; and

    writing said application data and operating system data within said first partition to said second partition on a sector-by-sector basis, such that upon an operating system failure, said application data and said operating system data may be restored from said second partition to said first partition without utilizing said filing level instructions.
