Yes it can. ZFS will only notice next time you scrub or read the sector.

  Sure, but your ZFS pool will have redundancy, and ZFS will know which block was corrupted. This lets it recover from the error.

    If the corruption occurred on disk, yes. If it occurred in memory then it will write multiple incorrect copies to disk.

      This is why ECC is important. Many many people poo poo the idea that it's needed. But by not having it you have left a single vital part of the data path unprotected. And ram and disk is cheap, losing your data is not. The risk simply isn't worth it to save literally a few dollars.

      That's no argument against ZFS, or backups, or any other form of redundancy. Only the insane would buy computers without ECC.
