Решил попробовать сделать таблицу разделов на GPT. И после перезагрузки получаю
kernel: sdb: unknown partition table
kernel: sdc: unknown partition table
kernel: sdd: unknown partition table
kernel: sde: unknown partition table
kernel: sdf: unknown partition table
Захожу в gdisk /dev/sdb
GPT fdisk (gdisk) version 0.8.6
Caution! After loading partitions, the CRC doesn't check out!
Warning! Main partition table CRC mismatch! Loaded backup partition table
instead of main partition table!
Warning! One or more CRCs don't match. You should repair the disk!
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: damaged
****************************************************************************
Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk
verification and recovery are STRONGLY recommended.
****************************************************************************
Problem: The CRC for the main partition table is invalid. This table may be
corrupt. Consider loading the backup partition table ('c' on the recovery &
transformation menu). This report may be a false alarm if you've already
corrected other problems.

Всё нормально.
Но после перезагрузки он опять не видит разделов. Как лечить?
