Disk not Ejected properly

Suddenly every time my mac goes to sleep, a notification appears saying the one of he disks does was not ejected properly.

Usually it my Time machine external disk I usually have another disk connected at the same, it clones periodically

What causes his sudden behavior. Never happened before

The external disks are connected through a dock - and have been since before the problem sarted

This is a indicator that one of the drives could be failing/operating in a state of failure.

Ouch. You are probably right

I had three external drives give me trouble. I was able to nurse them back using disk uility and disk warrior.

I suppose it is time to retire them At least one is not that old. Two are LaCie one is G-systems

Wonder how / why three (3) disks fail in quick succession. All failed disks are 4tb

I have several 2TB that are okay, so far

Any idea?

@lerogdouglas The people at G-Technolgies say that since the disks are bus driven it must be an Apple problem

What I can't understand is that in two days three 4TB drives would have gone south after having no problem for over a yer I have had this computer. I have several 2TB drives that haven't given me any trouble. One is continuously connected and makes a clone once a day

I erased two of the disk and since I was doing a secure erase with Disk Utility I left it on all night and it didn't eject

Any new ideas, and thanks
