История такая. В один прекрасный день было замечено что «вывалился» один из винтов в RAID 1. fdisk показал отсутствие «пациента». Онный был извлечен, внимательно осмотрен, прочитаны надписи, гласившие «Seagete Bararcuda 1000Gb Model:ST1000DM003». Далее для успокоения души «пациент» был подключен по средствам переходника sata-usb в обычную рабочую станцию. И, о чудо! f-disk сказал:
