Recently I am getting a mass of "Disk Not Ejected Properly" messages every time my iMac sleeps.
It's running the latest OS version and this is a very recent phenomenon.
Anyone else getting it? Or worked out how to stop it?
You could try leaving a disc in the drive.
Is there actually a disk attached? If there is, check the Energy Saver control panel and untick "Put hard disks to sleep when possible".
There are 4 attached.
I'll try that one.
These are things I suggested in two other posts for different problems, but they are worth trying for this as well:
delete the contents of these folders (it could be a corrupt cache file that's doing it)
Then restart. Then try this
Reset the SMC and the PRAM.
