External hdd won't eject properly since El Capitan

No it did not, I had the problem occur as soon as my Mac fired up after installing the update. I did notice my Notification problem was fixed though and I got the calculator back.

So hopefully the next update will fix it.

Latest update did not fix the Time Machine problem for me either.

I'm having the same problem - ever since the El Capitan os x update my external drives WILL NOT eject. My one backup drive was corrupted to the point Apple Genius Bar could not do anything with it (damaged internal software; could NOT unmount the drive). Thankfully I had done a backup before I came to the store - I bought a new 5T drive and I did a TimeMachine backup. The Genius bar wiped my laptop and restored from the newest backup, BUT I'm having the exact same problem. If my working drive (or my new backup drive) became corrupt that would be absolutely horrible, since I'm a photographer - loosing someone's wedding photos would basically not be an option...

I tried adding BOTH drives (the working one and the new backup) to the privacy thing, and that's not fixing anything. Still the same problem. Any other ideas? I've already had my OS X resinstalled..

To make the matter worse, I only have an El Capitan backup, so the Genius Bar told me that I cannot roll back to Yosemite for OS X, because it will not let me restore from an El Capitan backup...

HELP PLEASE?!

Gosh this is getting serious, I do hope my back-ups have not been corrupted, how does one check this anyway. I have entered Time Machine and all looks Ok. I suppose one must delete a file and then go to back-ups and replace it and see if all Ok.

If not how do we check the back-ups are good.

Today it happened to me soon after I woke the Mac up, it again replaced my back-up drive icon with another Mac hard drive one and put my back-up icon on a different part of the desktop. Resulting in two mac hard drive icons neither of which would eject.

I am thinking that it is happening more since the recent update of last week. I am leaving things as they are for a while as usually I reboot my mac to put things back to normal, going to see if I get another event ending up with three mac hard drive icons.

I hope everyone who is suffering this have put in a "Bug Report" to Apple as I was advised to do and did. Here's hoping for a fix asap. Quite annoying.

I finally had enough today... I ended up restoring my Macbook pro to the Yosemite (which was NOT easy - my husband ended up having to custom make a restore file on an SD card...). I am just loading everything back from a backup drive and performing new backups in the Yosemite. That OS is so much more stable, I've had problems with literally everything since the upgrade. I finally decided to roll back. I'd advice the same after my drive being corrupted (first time in my life such a thing has happened). I simply cannot risk more stuff like this happening.

More info, I just entered TM to have a good look around and after returning to normal screen I noticed the extra Mac Hard Drive icon had gone, so all at the moment is normal.

From my look see in TM all seems to be OK but later I will delete a pic or something and restore it and see what happens.

I am really hoping Apple will fix Time Machine in the next update, it is very important. Fortunately I have more than 1 backup, including Norton Online Backup, which backs up both my Macs weekly, and it does work with El Capitan.

My sentiments exactly. Something has changed in El Capitan to create this situation so Apple, I am sure will issue a fix in the near future.

I do feel that after all the beta issues to so many testers out there that these issues should really not happen. My question is "exactly what do they test and how come these things are not picked up?" they are not minor issues so how come they were not noticed.

I invite everyone dealing with this issue to report it to Apple if you haven't done so already at http://www.apple.com/feedback/macosx.html

For those with a developer account, please file a bugreport.

The more people send it in, the higher the chance (theoretically) that Apple will work on a fix. Just posting in the forum unfortunately is not enough.

Thanks.

Not a solution for everyone but an observation that could help finding a cause for this issue:

I recently put an SSD in my iMac where I cloned my System from the original HD on. The issue is gone whenever I boot from the SSD.
