На домашнем NAS под управлением Ubuntu 14.04 три диска: 60Gb, 1Tb и 2Tb. Самый большой перестал работать.
При этом биос его видит, но некорректно определяет размер. С lshw ситуация аналогичная:
$ sudo lshw -c disk

Команда df его не видит:

При выполнении fdisk -l тоже пусто:

Если попробовать получить по нему данные через fdisk возвращается вот такая ошибка:
$ sudo fdisk -u /dev/sda
fdisk: unable to read /dev/sda: Input/output error
SMART прочитать не удаётся:
$ sudo smartctl -a /dev/sda
