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)

I'm having the same issue with a USB 3.0 single drive enclosure. Mavericks keeps ejecting the drives and then I see the "disk not ejected properly" message. This is critical since these are my backup drives. It happens when my iMac goes to sleep or restarts.

I just got a voice mail from a Apple representative about this issue.

Unfortunately the connection was a little bad and the call kept interrupting, so I couldn't make out the email address he asked me to contact him...

If you are reading this, please do contact me via email. As of this morning, before I left for work, the problem still persisted.

Thanks

iPhabio, did you ever get an answer on this?

Ever since I upgraded to Mavericks on my early 2009 MacPro, upon wake up I get warnings that my usb3 "disk did not eject properly". I have tried everything suggested in this thread. I have contacted Seagate and have performed their firmware updates, but the problem persists.

With so many forums asking this same question, how is it that no one can get an official answer from Apple??

Apple-do, Where are you???

I too had the same issue. Apple support didn't have a solution. Bought the app "Jettison" and it totally solved the problem.

Just had a chat with Apple Support. They suggested enabling Power Nap. I'll give it a try this weekend (with a non-critical drive) and post whether or not it helps.

I don't believe the Power Nap option will work. I have the same problem and have had that enabled for a while. If you get better results, let us know.

No combination of energy saver options worked. I tried them all, using a non-critical drive. I then tried connecting the drive via USB rather than thunderbolt/fire-wire-800, which was worse. The drive kept connecting, then disconnecting, once per minute, with the dreaded "disk not ejected properly." Don't know if the issue is with the port on my drive or the system.

I did buy jettison for $2 on the app store, which seems to work! The only exception is when putting my iMac to sleep via the power button. I did have to change some of the defaults to prevent auto disconnect of network shares on sleep.

If a $2 app, helps this much, it would seem that Apple should be able to implement a quick fix.

Sounds like you took the same path that I took. I too purchased Jettison which seems to be working. And yes, you would think that Apple could provide an even better fix - long overdue IMO

Thanks tons for the follow-up. I too have tried all the power-saver options, most just made the problem worse, even ejecting my Drobo during backups. I'll have to try Jettison- maybe I can hook my drives back up again!

MAYBE A SOLUTION !

Unfortunately, I feel like an innocent who just caught Alzheimer. I had the problem and I solved it, but, believe it or not, I don't remember ho. I have a Seagate Expansion Drive that failed to mount at startup (unproperly ejected and so on) and I changed things in POWER NAP SETTINGS, then the problem disappeared.

ENERGY SAVER CONTROL PANEL:

My settings now are (originally in french so I may not translate properly)

1) Suspend disk activity when screen is off (checked)

2) DON'T suspend disk activity as soon as possible (unchecked)

3) Reactivate when accessing the network (Checked)

4) Automatically restart after a power failure (Unchecked)

5) DON'T Activate PowerNap (Unchecked)

SOLVED THE PROBLEM

I have a 27" iMac 2010. The hard drive was replaced last year. Using a Western Digital back-up drive. I have the same problem.

I do have this problem with Mavericks. I lost a 2 TB harddisk which canot be repaired anymore two weeks ago; it still mounted, at least.

Same problem appeared yesterday with another external disk, this time it can't be mounted with any repair software but accessed with Data Rescue only. However the disk is beeing ejected even during the recovery process (and whilst i am working on the machine). What a terrible hassle because i have to keep comparing the files already copied! ***??

I am having the same problem with a Seagate USB drive and a WD eSATA drive. The Seagate was plugged into USB 2.0, but just installed a USB 3.0 PCI card and am now using that. It ejects on either USB speed. The eSATA ejected itself (just added it yesterday) and it isn't even showing up in Disk Utility right now. I think this has only happened in Mavericks. It is very frustrating because I am not in the habit of having to remember to eject a drive before my Mac goes to sleep and I don't want to. My Mac Pro is an early 2009.

After having Jettison for several weeks now, I can't say it is really an end-all solution. I frequently see pop-ups that tell me Jettison is "working" but I am still getting "disk not ejected properly" errors. The integrity of my disks remains in tact - so far so good, but it's still irritating.
