several times of emergency shut down mybook, I want to make sure that there is no disk errors. Please tell me step by step how to do it.
There's usually no reason to do a manual fsck, because it should be run automatically at system startup. All errors are corrected by replaying the journal. So, your data should be safe even if you unplug the device…
Yeah but it would be good to know how! … fsck cannot be found on the White Light ones. However e2fsck does work but I dont know how to use it properly
