In-place disk unformatting

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. 提供了用于对盘进行就地去格式化的各种方法和系统。该系统包括被配置成用于在盘上创建备份文件的准备组件以及用于使用备份文件来占据盘上定义备份区域的预定位置的预格式化组件。备份文件是占位符，以使得预格式化组件将原始数据和文件表数
