Abstract
Various methods and systems for in-place unformatting of disks are provided. The system includes a preparation component configured for creating a backup file on the disk and a preformatting component for using the backup file to occupy a predetermined location that defines a backup zone on the disk. The backup file is a space-holder such that the preformatting component copies primal data and file table data to the backup zone. The system further includes a formatting component for formatting the disk storing the primal data and the file table and an unformatting component that copies the primal data and file table data from the backup zone back to their original locations to unformat the disk to a preformat configuration. A safeguard component may also be implemented to ensure that the preformat component is invoked before the format component if the preparation component was executed on a volume.
