Недавно я купил жесткий диск объемом 3 ТБ, который я вставил в корпус внешнего USB-накопителя и подключил его к linux debian.
К сожалению, теперь он показывает 2 отдельных физических диска: один с 2,19 ТБ и один с 801 ГБ.
Понятия не имею почему.
Я обновился до wheezy и ядра 3.2.48, но без разницы.
Вот мой вывод dmesg:

Теперь я могу просто создать два отдельных раздела и добавить их в одну сборку lvm, но, поскольку я понятия не имею, почему это происходит, я сначала хочу знать, почему.
