Abstract
A medium storage device reads device specific information from a medium to a memory and performs read/write operation to the medium, which allows receiving commands from a host even if a read error of the device specific information occurs. When an error occurs during the device specific information read processing of the medium storage device after power ON, the alternate data stored in the medium is developed so as to recover the power ON error artificially. For this alternate data, the data at factory shipment is saved in a ROM or a system area of a medium in advance, and is developed from here when necessary. Since commands can be received and executed, a disabled startup of the host system can be prevented.
