I have two Time Capsule's - a 3rd gen and 4th gen both running firmware v7.6.1.  1 is used as a TC (4th gen) and the other (3rd gen) is in bridge mode simply used as a NAS.  That said, the TC only spins up every hour as expected to perform the backup.  The NAS TC in bridge mode spins up VERY briefly every 5 minutes then immediately spins down.  Resetting this TC fixes the problem for several hours then it magically returns.  My question is, since both TC's are running the same firmware, why is one behaving different from the other?  Could this issue run deeper than just firmware?

    Yes, it is deeper issue.. 7.6.1 is not great on the earlier hardware..


    Most people who ask about it find that flashing firmware back to 7.5.2 will fix it without causing any issues.. Simply hold the option key when you select firmware update.. and turn off the weekly check for firmware upgrades.. although it will still occasionally flash amber asking to update to the latest worstest firmware.


    And it is good you are taking it seriously.. the hdd will be ruined with continuous spin up and down and particularly parking of heads which some of the green drives are renowned for.. they blow up in fairly short order after that.

    Later Gen 4 cannot be flashed back to 7.5.x firmware.. the first production run did come out and they still work.. but apple changed the later ones.. simply cannot be flashed back.


    For early OS up to SL I recommend sticking with 7.5 firmware but later ones it depends.. apple added a few functions like the btmm via icloud.. although if your TC is older one.. even if gen 4 and can be flashed back.. if it is bridged it won't hurt being back at 7.5.2.
