Здравствуйте, уважаемые! После нескольких месяцев нормальной работы вдруг стал отваливаться внешний винт Seagate srd0nf2. Пару раз помогло вытащить и вставить назад, но теперь так просто он заводится не хочет. Во-первых, не с первого раза обнаруживается в lsusb, а если и обнаружится, команды вроде
mount -v /dev/sdf1 /mnt
ls -l /mnt
#fdisk -l
...
