отменить rm в gparted - восстановить раздел? отменить операции?

Я случайно удалил раздел на основном разделе. Я думал, что на съемном диске. Я явно должен был обратить на это больше внимания ... Я не "сохранял" или "выходил" из parted, но похоже, что раздел пропал! Есть ли способ отменить это? Parted просит меня сохранить при выходе, и я могу просто сказать нет?

[root@localhost ~]# parted

В соответствии с предложением ниже я запустил testdisk. Однако из-за того, что это зашифрованный раздел, testdisk не нашел конец раздела должным образом. Теперь я вижу это:

You have to reboot for the change to take effect.

Из руководство:

Только после выхода из Parted ядро ​​Linux узнает об изменениях, которые Parted внес на диски. Однако изменения, вызванные вводом ваших команд, вероятно, будут внесены на диск сразу после ввода команды. Однако кэш операционной системы и аппаратный кеш диска могут задержать это.

Вы можете выйти, а затем попытаться восстановить раздел; учитывая приведенную выше информацию, это должно быть очень просто.

Если parted не может восстановить раздел, я бы предложил использовать testdisk: http://www.cgsecurity.org/wiki/TestDisk

Существует довольно подробное руководство для testdisk Вот: http://www.dedoimedo.com/computers/linux-data-recovery.html
