Description
本開示の第1の実施の形態について、図面を参照して詳細に説明する。図1は、本実施の形態に係るディスク装置10の構成の一例を示すブロック図である。本実施の形態に係るディスク装置10は、図1に示す通り、一つの構成例として、駆動部11、センサ12、判定部13、送信部14、記憶部15、制御部16、バッテリ17および入出力インタフェース18を備える。また、ディスク装置10は、スイッチ19を更に備えてもよい。なお、ディスク装置10は、この他に、データを記録するための記録機構(不図示)や外部電源と接続するインターフェース(不図示)等を備える。ディスク装置10がHDDである場合には、データを記録するための機構には、例えばデータを記録するプラッタ等が含まれる。
なお、センサ12が検知した受ける影響の検知結果がディスク装置10の故障に繋がる条件を満たす(悪環境)であることを、管理者2に把握させる方法は、表示することに限定されず、音や振動で知らせる方法を採用してもよい。また、送信部14が送信する情報に、センサ12の種類や異常の程度を表す値が含まれている場合、外部機器32は、センサ12の種類や異常の程度を表す値に応じて異なる方法で、管理者2に対し、検知結果を把握させてもよい。
次に、本開示の第2の実施の形態について、図6を参照して説明する。本実施の形態では、本開示の課題を解決する最小の構成について説明を行う。
