At least with bigger SATA disks I see regularly checksum errors on btrfs/ZFS and a rising bad sector count. The disk usually replaces the sectors on the next write but when reading it returns either zeros or wrong data. It's nice to know what files are affected from bad sectors. It's not common but common enough to have it.
- userbinator 10y agoWhat sort of "bigger SATA disks" are you using, or how are you treating them? If I see one bad sector develop on a disk for no obvious reason, it's getting replaced ASAP because it's a sign that more will follow very soon.
