Q: Disk not ejected properly

Hi I'm having this issue since I upgraded to Mavericks where almost every time I put my computers to sleep I get the "Disk not ejected propoerly" message and every disk but the system one is not mounted and cannot be found by Disk Utility.

 

I have a Mac Mini late 2009 and a Macbook Pro 15 mid 2009 and I'm having this issue in both machines. Never had any issues before in any of my machines, not in Leopard, Snow Leopard or Lion.

 

On my Mini I have two external USB drives and on my MBP I have a SSD, where the system is installed, and a HD (I replaced my optical drive with a bay to install the extra disk).

 

I researched the issue and found a couple of threads where people sugested to buy a 3rd party app that would unmount the disks at sleep and remount them at wake, but I think this shouldn't be a issue, since it never happened with any version of OSX I had used before.

 

Is anybody else having this issue as well? Is there any word from Apple on this subject? Can I hope for a fix?

 

Thanks

MacBook Pro, OS X Mavericks (10.9)

    Apple still has no answers after 32 pages of complaints? Pitiful. I have two brand new Macs with El Capitan on my domain and have the same issue. Every morning, I come into the office and check both new Mac Desktops and see this error message, Disk not Ejected Properly. I only have one ext hdd plugged in on both Macs, strictly for Time Machine backups. If I cannot backup my Macs, then what is this new OS really for? We need answers and/or a fix. Both macs are updated with the latest Apple updates, yet still receiving the same error message every morning after waking up both computers. I disabled sleep mode and kept them on overnight. This did not resolve the issue at hand. I come in every morning and still see this same error message. I have 6 other Mac Pro desktops with Yosemite installed and no problems with the same ext hdds plugged in for only Time Machine backups. Please fix this Apple!!!

    Its very sad to me that due to this issue happening every day on both my quite expensive macs that I have had to revert to booting up with bootcamp and using Win10 instead.  At first to prove that this was not a hardware issue,  which I have now proved its not,  windows logs show no disconnection of usb devices, and overnight backups are always successful.  My macs do not just do this when sleeping as none of them were set to sleep and it often happened while copying files to hard drives.  Apple's non response on this issue has been really annoying and quite disgusting as its obviously an issue and being forced to go to Windows to make it work is quite pathetic.

    One part of this I dont get,  why "pull the system configuration folder to the desktop",  this folder cannot be moved nor deleted as the system will not let you,  so making a copy of it on the desktop seems pointless.

    I can't see how this solution will accomplish anything other than confusing my Mac naming.  I have had the "disk not eject properly" problem for several years, and have over that time spent tens if not hundreds of hours with Apple on the phone trying to fix it.  I should note that only reluctantly would support allow my question to be passed along to technical.  At that time, about a year ago, I was told that it was the fault of my external drive or external hub.  I have an external HD (raid) running as TM which has (fingers crossed) worked now for several months without more than a handful of dneps.  Likewise, my image archive HD, a WD MyPassport plugged into the iMac worked fine until several weeks ago.  Then in the last few days it repeatly and sometimes rapidly dneped.  When I hooked it into my external powered hub, it worked fine for almost a day.  Then the same thing started happening.  Apple has never addressed this problem wholesale; hasn't included any simple means of diagnosing the problem (if it is one with the drive or connections - my disk utility said the WD was fine).  If the problem relates to some kind of machine address cache which gets dumped in the process of changing the machine name, then Apple should provide a more direct way of deleting that cache.  While I appreciate you effort, I am not about to spend hours reconstructing files etc., if it doesn't work.  Apple should address this issue directly.  At one time I was told they would be; others have gotten a similar indication, but nothing has come of it.

     

    Given the complaints about El Capitan so far, I am leery to update from Yosemite to it.  If, however, it would accomplish the same effect as your workaround, I am almost more comfortable in doing that than the workaround that some Apple employee came up with.  (PS - did she say if this would have to be done each time there is a dnep?  Have you had any more dneps?  What's your OS X?)

    I get them all the time with El Capitan, pretty much every day when I come in to work.  It is pretty bad that Apple has never addressed this problem.  Thankfully it doesn't actually seem to cause any harm, at least so far...

    I put a new connecting cable from the Mac to the ward drive. No problems whatsoever since, but it did it 100% of the time before.

    As with alisonfromulverston I replaced the USB 3.0 cable on my external RAID and haven't had a single DNEP error since. You should try it.
