7.6 firmware causing USB disc spin up/down?

Hi

I have an Airport Extreme which has a USB disc and two printers hanging off it.

 

The Disc has two partitions, one of which is a Time Machine backup; the other has some shared files.

 

Time Machine causes the disc to spin up every hour, and sometimes when I use the Finder or an Open Dialogue, the disc will spin up to access the other partition. In either case the disc spins down after about 30 seconds of idle time.

 

Since installing 7.6 firmware, the USB disc spins up every couple of minutes, and as soon as the disc heads have loaded and the disc has finished rattling - perhaps 2 seconds after the whirring has reached running pitch - it spins back down.

 

I've done all the obvious - rebooted all the Macs sharing this disc, rebooted the Airport, powered down the disc and added it back in. All to no avail.

 

Does anyone else here see the same behaviour, or is this just a horrible coincidence occasioned by something else I may have changed?

 

Thanks!

iMac, Mac OS X (10.6.8)

    Since installing 7.6 firmware, I am observing the same behavior on my Time Capsule.

    AppleCare led me through the following steps, which solved the problem:

     

    1. In Airport Utility, select the Time Capsule.

    2. Select Manual Setup

    3. File -> Export Configuration File -- save it somewhere

    4. Base Station -> Restore Default Settings

    5. Wait for it to restart with default settings

    6. File -> Import Configuration File -- use previously saved file

    7. Press the Update button

    8. Wait for it to restart.

     

    You may need to re-enter the various network passwords. Be sure to use the same ones as before, or you will have to change the password on all your computers and devices that access the Time Capsule / Base Station.

    I have the same issue here. Since installing the 7.6 firmware the external USB drive of my Airport Extreme is spinning up and down like crazy, every 1 or 2 minutes. And for a very short time, just when finished spinning up, it spins down again. Very annoying and for sure not healthy for the drive either.

    Same issue here, too.  External drive powers up and down every couple of minutes.  I also get a very brief (1 second) dialog that says "Server Connection Interrupted".  I'm able to access the Time Capsule as normal and the light stays green.  Bus, as goligo says, above, this can't be good for the disk.

    I also tried the steps described by DESF. While it first looks like the issue was gone (no more spin ups for the evening), the next day the spin ups were back. I noticed just restarting the Airport Extreme and reconnecting the drive has the same effect. It remains silent for a few hours, then starts to spin up and down again.

    Downgraded to 7.5.2 again. It's very easy, just open Airport Utility, chose "Base Station" from the menu and then "Upload firmware...". The configuration is preserved.

    Following advice posted here, I downgraded to 7.5.2 as well.  While this did solve the problem of disk spinning up/down, the other Airport Expresses on my network did not come back online.  I was able to rectify this by rebooting my Airport Extreme and each Airport Express again.  Everything working perfectly now.  Thanks to all posters for your help.

    In case Apple Support people are keeping track of the number of people that are having problems, I wan to add that I am experiencing the exact same symptoms. Started with the update to 7.6.

     

    I don't have a hub, I have an external drive connected directly to my airport extreme time capsule.

     

    I'm concerned that the constant power cycling of my external drive is going to shorten its lifetime.

    Yep, count me among the masses downgrading to firmware 7.5.2.  Thanks for the input on how to downgrade.  Not sure I'd have found that on my own.

     

    7.6 indeed needs to be fixed.

    Having the same problem (Server Connection Interrupted), but not sure how you all are downgrading to 7.5.2. I can't find the software hosted anywhere to download. Did I miss a link in the above thread?
