Disk not ejected properly

After installing Lion yesterday I keep getting a window popping up from time to time with the red excllamation point saying the disk was not ejected properly.

But at no time had I disconnected anything. Just woring on the iMac.

There doesn't seem to be a way to find out what supposed drive/disk was ejected.

Any ideas or anyone else seeing this or know how to figure out what disk/drive the error message is referring to?

while your approach helped you the connection does not appear to be the solution.

i have replaced the backup drive, USB cables and the USB plugs in the computer.

I also note that the old drive works perfectly on windows machines as I passed it on to a co-worker.

the old cables also appear to work perfectly as they were passed on too!

I also note that this happens on both my iMac and my Mac book pro!


so to sum it up:

1. new hard drive in computer - still problem!

2. new back-up drive - still problem!

3. new cables - still problem!

4. new USB plugs in Computer - still problem!

5. connecting thru firewire plug - still problem!

6. service center - for check up - they gave up! still problem!

7. reloaded OS numerous times - still problem!


I am convinced that it seems to be a OSX problem.


I also note that I contacted Apple and they said they never heard of this problem. Hmmm!


Maybe there was more than one reason that Scott Forrestal, who developed time machine and the maps application was fired.


Yes, I am mad about this. been going on for about 4 years now. sometimes it will go for days without ejecting, then sometimes it will eject 5-6 times in a session.


i am glad you seem to have had an improvment, but believe it or not the problem will still exist.

Partyguy, you're so right. I'm trying it now.


My particular problem is a USB 3 card inside my Mac Pro. When the computer sleeps the card sleeps too (I'm told) and so the drive loses contact with the computer. When it wakes the computer tells me the disk unmounted incorrectly each time and though it mounts itself back, I have to OK click the window that announces that.


The same drive connected to an eSATA card wouldn't remount itself and so it was far more tedious to get it going again.


So far - with one test of the app (they allow 5 days trial) it does it's thing. It does all the external drives at once - which I don't need - but they all seem to come back online well and true.


Thank you Partyguy.

In the past few days, after installing latest Lion security update, I've been having several external hard drives experiencing what appears to be bad sectors. Disk Utility chokes when trying to repair as well as Disk Genius 3.

Luckily I have backups and had to erase the offending drive and restore from backups.


I use CCC to do archive backups of my main drives, 6, to external BUs each night.


This morning both one of the main drives and its backup had bad sector errors during CCC backup.


What's going on? Appears Apple has an OS X problem they are not owning up to.
