Methods and systems to access data in a computer system independent of an operating environment of the computer system, including to recover data to a remote system, to overwrite data, and to copy data to a hidden partition. A management system may directly access a storage device of the computer system and communicate with the remote system over a data channel that is secure from an operating environment of the computer system. The management system may access the storage device on a block basis, using a device driver associated with a storage device controller, and may include a virtualization engine to access the storage device. The remote system may include logic to request meta-data, to identify disk blocks corresponding to files of interest from the meta-data, and to construct the files of interest from the disk blocks.
