问题

超级用户读者chris想知道格式化后硬盘是否会记住坏扇区：

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?

格式化后硬盘是否会记住坏扇区？

答案

超级用户贡献者benn和harsh为我们提供了答案。首先，Ben N：

NTFS remembers bad clusters. A cluster is c***idered 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.

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.

接着是哈什的回答：

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.
