Q: Disk Drive ejecting itself

My Time Machine disk drive has been "ejecting" itself since I installed Snow Leopard. I'm not unplugging it, or turning it off. I'm not touching it.
I'm getting the following error message:
"The disk was not ejected properly. If possible, always eject a disk before unplugging it or turning it off."

My question is why would a disk drive be "ejecting" itself. I've turned off the auto backups, and unselected the drive as the backup disk. It is still "ejecting" itself which leads me to believe the problem isn't with Time Machine but with something else - something connected with Snow Leopard because this wasn't happening five days ago before I installed SL.

    +1.

    Several external USB powered HD's ejecting spontanously, sometimes when reading from disc.

    Very annoying and bad for my data.

    Verified data integrity, permissions etc. with several pro tools. Everything checks out on the HD side.

    Definitely an OS issue. Please get on this people.

    Yes, everyone should open a bug report ticket with Apple. Nothing has come from mine (they asked for some logs, adn that's the last I heard).

     

    Data Robotics just posted a KB article about this issue, mentioning a patch to work around it:

    (Drobo provided me with a patch for 10.6.7 to resolve the USB eject issues. They said the patch came from Apple, and will be part of 10.6.8.)

    10.6.8 has now come out. Has anyone install it and want to test it before we all install it?

    I installed 10.6.8 an hour ago but for some reason, I cannot now get past the spinning gear (they're actually stuck!) so I am resintalling the OS. I can't get into safe mode, tried the PRAM thing, etc. but no joy. GRR!

    I have now installed 10.6.8 and was successful with the install from 10.6.4. I have repaired permissions and now will begin testing (my computer and drobo are "on" 24/7). If it drops, I will report immediately. Wish me luck.

     

    BTW, after installing, after the first restart, I saw the gray screen that lasted about 3-4 minutes, then saw my log in screen. After logging it, it took another 4-5 minutes before I saw my desktop. My drobo appeared on the desktop without any problems. Drobo dashboard is working nomrally.

    I have installed 10.6.8 and attached the new USB drive that was constantly umounting. I am doing things like syncing my iPad, which used to almost always cause things to lock up.  So far so good.

     

    Now, does anyone know if I can get the previous external drive that was destroyed by the constant unexpected unmounting and re-mounting replaced by Apple?

    Correction: It seemed much better at first, I downloaded a few GB of updated apps via iTunes, but the drive has mysteriously stopped responding twice while doing other things in iTunes and locked iTunes up.....Maybe better, but not fixed.....

    Grrrr! Not fixed! Unless my external harddrive has succumbed to being dismounted so many times!

    I'm experiencing the same issue, and PARTIALLY RESOLVED.

     

    I have two different brand external HDD enclosures, using USB cable, with two different size HDDs:

    1. Some cheap generic brand enclosure + Sam Sung 750GB, never experiened this problem.

    2. MacAlly G350SUA + Sam Sung 2TB, constantly getting ejected drive message in 15-20 min, even when not doing anything.

     

    My fix:

    Swapped the case -- used the cheap enclosure with 2TB HDD, and no problem -- I'm doing TM on it. 

    (Haven't tried 750GB with MacAlly's yet if the problem persists with different drive.  If so, it's the case problem.)

     

    Not sure...

    - Is it possible that this is the external HDD case issue?

    - Or, when I first had this problem, after trying many things, I gave up.  Then a couple of weeks passed then tried swapping the case.  Not sure if there was any OS patch was applied between the time.

    for what it's worth, I switched from a LONG usb cable to a very short one. I'm not sure it's related but no more auto-ejects - 2 weeks going strong...

    I had ClamXAV scan my usb drobo all night (has over 1 TB of data). So far no drop (however, scan is still running, it is a lot of data). I also have a external USB WD Passport Drive (1 TB) that is used as a Time Machine. I just noticed that after upgrading to 10.6.8, that Time Machine has not run since yesterday,  even though the Passport Drive was selected as the TimeMachine, it did not run (icon was colored "Orange"). I went to the system preferences, and went to TimeMachine and selected the WD Passport, and TimeMachine is now running again (Now has "Green" color icon). I will report if it drops.

     

    I have now turned on my USB Samsung Story 1.5 TB external drive (has two partition, Clone of my internal drive, and another TimeMachine). I will report if this drops.

     

    So far, no problems. (runnning for over 12 hours).

    Happy to say 10.6.8 seems to have resolved an issue I traced to my particular USB chips inside my iNEO drive.  Read back or search my name to get the gory details.

     

    I think this "problem" was nothing more than certain USB chip makers taking liberties with the USB interface specifications, that had the effect of dropping the ball when a lot of data was flying around.

     

    They (Apple) likely just added a more generous timing to work around it.  Odd no menrtion of any USB bus changes in the description - tch tch.

    Just tried the problematic USB enclosure (MacAlly G-S350SUA)+HDD that I never had this ssue. -- Same result. "eject" problem.  It's the case.  May be USB chip in it, as someone wrote.  I'm applying the latest OS update right now, and will see if that fixes the problem.
