硬盤格式化工具 標記壞扇區

If you start encountering bad sectors on your hard drive and decide to format it, will it “remember” those bad sectors afterward or not? Today’s SuperUser Q&A post helps answer a curious reader’s question about bad sectors and formatting.

如果您開始在硬盤驅動器上遇到損壞的扇區并決定對其進行格式化，它是否以后會“記住”這些損壞的扇區？ 今天的“超級用戶問答”帖子有助于回答好奇的讀者有關不良扇區和格式的問題。

問題 (The Question)

SuperUser reader chris wants to know if a hard drive remembers bad sectors after formatting:

超級用戶閱讀器克里斯想知道格式化后硬盤是否記住了壞扇區：

On an NTFS-formatted hard drive with some bad sectors, does the hard drive still remember those bad sectors after Windows diskpart clean is used to remove the NTFS volume? What if clean all is used?

在具有某些壞扇區的NTFS格式的硬盤驅動器上，使用Windows diskpart clean刪除NTFS卷后，硬盤驅動器是否還記得那些壞扇區？ 如果使用全部清潔怎么辦？

Does a hard drive remember bad sectors after formatting?

硬盤格式化后是否還記得壞扇區？

答案 (The Answer)

SuperUser contributors Ben N and harsh have the answer for us. First up, Ben N:

超級用戶貢獻者Ben N和harsh為我們找到了答案。 首先是Ben N：

NTFS remembers bad clusters. A cluster is considered bad if any sector in it is not accessible. Since the bad cluster information is stored in a specific file ($BadClus), that information will be destroyed if the NTFS volume is removed. clean and clean all are essentially the same in that regard. clean all does a more thorough job of destroying the disk’s data while clean just wipes the partition table.

NTFS會記住不良群集。 如果群集中的任何扇區不可訪問，則將其視為損壞。 由于不良群集信息存儲在特定文件( $ BadClus )中，因此，如果刪除NTFS卷，該信息將被破壞。 清潔和清潔在這方面基本上是相同的。 clean all可以更徹底地銷毀磁盤數據，而clean只是擦除分區表。

進一步閱讀： NTFS系統(元數據)文件

The hard drive is what remembers bad sectors. Exactly how it does that depends on the model, but most modern hard drives automatically detect and remap dead sectors so that the operating system does not even know there is a problem. In that case, nothing the operating system does can affect the disk’s internal bookkeeping.

硬盤是記住壞扇區的地方。 確切的操作方式取決于模型，但是大多數現代硬盤驅動器會自動檢測并重新映射死區，因此操作系統甚至都不知道存在問題。 在這種情況下，操作系統不會做任何事情來影響磁盤的內部簿記。

Followed by the answer from harsh:

其次是苛刻的答案：

If the operating system is encountering bad sectors, then the hard drive’s internal bad block table is probably full (as Ben N pointed out) and it is time to retire the hard drive. Hard drives typically do not stop failing.

如果操作系統遇到壞扇區，則硬盤驅動器的內部壞塊表可能已滿( 如Ben N所指出的 )，是時候退役硬盤了。 硬盤驅動器通常不會停止故障。
