Не разбивается диск в gparted

Доброго времени суток.
Хочу создать новый раздел на базе sda2, для этого нужно sda2 разбить на две части, что у меня и не выходит (см скриншот 2).
Уголок новичка: Не разбивается диск в gparted

На других форумах люди писали проверить через smartctl -a /dev/sda, хоть я и не понял зачем). Но тем не менее, код тоже привожу ниже:

Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

UPD:
Почему-то скриншот не загрузился, но смысл в том, что диск, который я хочу форматировать /dev/sda2 формата ext4 занимает почти все пространство, и когда я хочу его разбить на разделы, пишет что минимальный размер равняется максимальному, и соответственно его никак не изменить.
