My iMac (late 2009, current OSX) often gives me the "Drive not ejected properly" message when I have not knowingly attempted to eject a (USB 2.0) drive. This happens with both hard drives & USB thumb drives. I can usually unplug the drive & plug it back in with no loss of data. My Drobo/RAID, which seems to have issues of its own, often is difficult to re-start.
iMac 27" & Macbook (White), Mac OS X (10.6.2)
I eject a drive by either dragging the icon to the trash, or (more often) ejecting from within Finder. However, these "Drive did not eject properly" messages appear when I have not ejected the drive. Until recently, this was only a minor nuance & had never happened while I was saving a file. However, my last backup (using SuperDuper) failed when the backup was interrupted. A 2nd attempt yielded the same result. The backup was of 2TB+ of RAW photos from the Drobo. With the old (late 2009 USB 2.0) iMac, this is a very long backup - about 10 hours. I have not tried the SMC & NVRAM resets. This is a great suggestion & I will give it a try. Thanks
No - I have not attempted a restart in safe mode - another good suggestion that I will try. While I can attempt this & the SMC and NVRAM reset, my backup drive is safely stored in a bank safety deposit box - unavailable to me until the holiday weekend is over. Additionally, since this is an intermittent problem, I will be unable to determine if the problem is truly fixed for a while. Thanks for the (very) helpful suggestions.
Have you attempted to restart in Safe Mode?? If not please use Use safe mode to isolate issues with your Mac - Apple Support
Explain how you eject it as there are multiple methods. Also have you done a SMC and NVRAM reset?
