Go to the third icon of the six on the bottom right corner click system configure>general setting>video log storage "set location" the one with the question mark is unable to store footage so just delete it from the storage options and make a new one if you want I have disks E F H and E doesn't seem to work so I just deleted it and later I can fix it if I want but it will get your footage in the meantime. it will also let you decide what cameras you want the videos stored in specific disks so just check off the cameras corresponding with their camera numbers hope this helps~
