    摘要: According to one aspect of the invention, methods and systems for operating a magnetic storage media drive to perform read/write operations to magnetic storage media in an overwrite protected mode are provided. In one example, a method includes receiving a write request and associated write data and determining if the magnetic storage medium is overwrite protected. If the storage medium is overwrite protected the method includes writing the write data to the storage medium followed by an EOD marker associated with the end of the write data, allowing write operations to the storage medium after previously written data, and preventing write operations to the storage medium prior to previous EOD markers.

    摘要: A controller for a well facility has at least one electronic control module (20) and at least one power switching module (21, 22). The power switching module may provide either a wholly hydraulic or wholly electrical output. The distributed electronic and power switching controls facilitate their removal and replacement by a remote operating vehicle. The modules are preferably housed on a subsea well tree (31).
