compatible external drives with Time Machine
Where can I find a list of compatible external hard drives that will work with Time Machine. Also I have an older Airport Extreme base station and I would like to know if it is recommended to connect the external drive (that will be used with Time Machine) directly to my iMac or should I connect it to the Airport Extreme or does it not matter?
iMac (27-inch Late 2009), OS X Mountain Lion (10.8.2)
