According to one embodiment, a data storage apparatus includes a read module, an error detector and a controller. The read module is configured to read data from a flash memory, more precisely from a rewrite area and a write-back area, both provided in the flash memory. The error detector is configured to detect errors, if any, in the data read. The controller is configured to keep rewriting data, without correcting the errors the error detector has detected in the rewrite area of the flash memory.

Data storage apparatus and method for writing data

Among plural types of signals sent/received between a computer (PC) and a extension unit (extension adapter), a predetermined signal group is converted to a serial data and delivered through a serial bus, and a specific signal directly affecting the operational-speed is directly delivered through a direct signal line so that the number of connection signals between the computer and the extension unit is reduced while keeping the operational-speed from lowering, a connector can be made smaller, and the device constitution of the entire system can be compact.
