    The drive connected to the AirPort Extreme would be considered a "network" drive....while the drive connected to the iMac would be be considered an "external" drive.


    If you are asking about Time Machine backups, Time Machine stores the backups differently for each type of drive location.


    And...Apple does not officially support Time Machine backups to a drive that is attached to the USB port of the AirPort Extreme, so best to connect the drive directly to your iMac if you plan to use Time Machine for backups.

    When a drive is plugged into the AirPort Extreme, the base station shares it over the network if it can. This makes it more easily accessible to other machines on the network(if it was plugged into a computer, that computer needs to be on and awake to share it) but also prevents it from being repaired from a computer. Drives connected to an AirPort base station need to be formatted as Mac OS Extended, FAT16, or FAT32; the filesystem capabilities of the computers on the network don't matter.
