What happened:
The "Bad sectors" and "Current Pending" report "-1", but smartctl reports this raw value at 4294967295.
What I expected to happen:
The reported raw value should be as reported by the disk (4294967295).
What seems to be the problem is that this raw value (pretty_value) is of uint64_t type in libatasmart/atasmart.h (typedef struct SkSmartAttributeParsedData), but it casted to gint when printed by gnome-disk-utility (gnome-disk-utility-2.30.1/src/gdu-gtk/gdu-ata-smart-dialog.c: 1615). Some SMART data seems not to keep the real count of sectors, but their own raw value.
smartctl output:
