Abstract: Described are a storage system and a method for adapting to an incompatible disk drive that has been installed in a storage enclosure. An adapter board receives a signal from a control board that indicates a type of the control board. In response to the first signal, the adapter board determines whether the type of the control board is compatible with a disk drive that is installed in the storage enclosure. If the control board is of an incompatible type, the adapter board sends a signal to the control board that causes the control board to bypass the installed disk drive.
