A bad sector on a HDD means one or more bad blocks are of out of spec on the disk magnetic surface area. The only way to locate those blocks is to try to read every single block on a hard drive. HDDs are slow so that will take a lot of time. For example, a modern HDD has real world read throughput around 130 MB/s, so a modern 4TB disk will take around ...

If the files copied over successfully, without errors, it is highly unlikely that you will have problems with them. With that many sectors failing I would certainly prepare to replace that hard-drive before long, go ahead and start doing backups for an important documents or media just to be safe. Generally if a file is being copied from a corrupted sector ...

Why do damaged hard drives freeze entire system? They don't have to (in general). It's really depending on the particular file system how a disk failure is dealt with. Consider ZFS, which is designed from the ground up to deal with quite some fault tolerance. Here's a demo video (and one with more explaining) where they place running drives on an ...

As was stated above, the issue with system freezes due to a bad hard drive is primarily due to long attempts by the drive to recover unreadable data from bad sectors. One of the selling points of enterprise drives is the very short read timeout for failed sectors. Using an enterprise drive can mitigate your issues to some degree, but will not solve them. ...

I think the problem you are encountering is a low-level part of the OS tries numerous times to read bad blocks before giving up. This routine is implemented at a low-level in case it is needed during booting or other standalone operation, and hence it is difficult to make it re-entrant. The operating system will page continually during normal operation and ...

This is one of those areas where SATA is suboptimal. The problem is at the storage device interconnect protocol level, and thus not related to what software you are running. Using another file copier or another operating system won't magically make things better, except that it might try to set different timeout values to reduce the impact of the problem ...
