Да, видимо где-то на этапе разметки возникла ошибка.
Отформатировать диск (раздел) из командной строки можно по примерно такому сценарию:
1. Создать таблицу разделов и основной раздел на новом диске:
bubnov@zentyal:~$ sudo fdisk /dev/vdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x91bb71f5.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command (m for help): o
Building a new DOS disklabel with disk identifier 0x76d22220.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
bubnov@zentyal:~$ sudo fdisk /dev/vdb
Command (m for help): n
Partition type:
p primary (0 primary, 0 extended, 4 free)
e extended
Select (default p):
Partition number (1-4, default 1):
First sector (2048-16777215, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-16777215, default 16777215):
Using default value 16777215
Command (m for help): w

bubnov@zentyal:~$
После создания раздела он появится в выводе:
bubnov@zentyal:~$ sudo fdisk -l

2. Отформатировать наш раздел:
bubnov@zentyal:~$ sudo mkfs -t ext4 /dev/vdb1
mke2fs 1.42.9 (4-Feb-2014)
Filesystem label=

bubnov@zentyal:~$
3. Смонтировать новый раздел:
bubnov@zentyal:~$ sudo mkdir /media/test
bubnov@zentyal:~$ sudo mount -t ext4 -o rw /dev/vdb1 /media/test
bubnov@zentyal:~$ df -h
Filesystem Size Used Avail Use% Mounted on
...
/dev/vdb1 7,8G 18M 7,4G 1% /media/test
bubnov@zentyal:~$
Выше приведён вывод реального сеанса подключения нового диска к виртуальной машине с Zentyal 3.5. В Вашем случае пункт 1 скорее всего не нужен.
И да, вместо /dev/vdb будет /dev/sda
