IDENTIFY DEVICEコマンドによるHDD情報の取得

More than 3 years have passed since last update.

■IDENTIFY DEVICE

ATAのIDENTIFY DEVICEコマンドにより、HDDやSSD等の固有情報や現在の設定値などを取得できる。
取得できる項目一覧(の一部)を以下に抜粋する。

IDENTIFY DEVICEの情報を見るには専用ソフトが必要で、フリーソフトのCrystal Disk Infoが有名。
ベンダー固有の項目や、現在では使用されていない項目もあるので、以下は参考程度。
Word型(2byte)単位で表示される項目が多いが、1bitごとに意味を持つ項目もあり、
「何Word目の何bit」の形式で各項目は表記される。
