У меня есть внешний USB-жесткий диск с шифрованием LUKS (1 TB HGST Touro S). Если я вставлю диск в новый USB-корпус, это уменьшит число секторов на 1, и я больше не смогу смонтировать файловую систему.
Есть ли способ исправить это без переформатирования жесткого диска?
В старом корпусе USB:
sudo fdisk -l /dev/sdd
Disk /dev/sdd: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xe8070000
Disk /dev/sdd doesn't contain a valid partition table
sudo fdisk -l /dev/mapper/touros_old
Disk /dev/mapper/touros_old: 1000.2 GB, 1000202788864 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953521072 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/mapper/touros_old doesn't contain a valid partition table
sudo fsck.ext4 /dev/mapper/touros_old
e2fsck 1.42.9 (4-Feb-2014)
/dev/mapper/touros_old: clean, 450506/61054976 files, 208726295/244190134 blocks
Теперь, если я заменю жесткий диск на новый USB-корпус, произойдет следующее:
sudo fdisk -l /dev/sdc
Disk /dev/sdc: 1000.2 GB, 1000204885504 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953525167 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xe8070000
Disk /dev/sdc doesn't contain a valid partition table
sudo fdisk -l /dev/mapper/touros_old
Disk /dev/mapper/touros_old: 1000.2 GB, 1000202788352 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953521071 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/mapper/touros_old doesn't contain a valid partition table
sudo fsck.ext4 /dev/mapper/touros_old
e2fsck 1.42.9 (4-Feb-2014)
The filesystem size (according to the superblock) is 244190134 blocks
The physical size of the device is 244190133 blocks
Either the superblock or the partition table is likely to be corrupt!
Abort<y>? yes
