This can never be ignored and is never a false positive. It means that
the drive knows that 30 of its sectors became unreadable. The data
there, if any — it can still be space outside a filesystem — is lost. If
you have no redundancy (RAID, LVM mirror, btrfs, zfs, …) you may have
lost data.
I thought we said earlier that redundancy wasn't a backup, and
vice-versa, so Bruce better have backups, no?
