 +|  5|Reallocated_Sector_Ct|ハードディスクが読み・書き・検証エラーを見つけ、代替させた不良セクタ数。通常、代替セクタが発生しても気が付かないが、より多くのセクタが代替されるほど、ディスクの読み書きに影響を及ぼす。|
 +|196|Reallocated_Event_Count|不良セクタから予備領域にデータを移した回数。データ移行に失敗した数も成功した数と同様にカウントアップされる。|
 +|197|Current_Pending_Sector|不安定なセクタ数。代替セクタに再配置されるのを待っているセクタの総数で、正しく読み取りできたばあいは除かれる。但し、エラーが発生する場合は代替セクタに移されて、不良セクタはマークされる。この値がゼロで残るならば、対応する領域の質が低いことを示す。|
 +|198|Offline_Uncorrectable|修復できないセクタの読み書き時のエラーの量を示す。この値が増えることは、ディスクの欠陥・機械的なサブシステムに問題があることを示す。|
