I'm not sure when this issue stared. Maybe with latest os x update.
When I boot my mac mini, I hear a click click click that makes it wait to proceed.
The click noise come from my wd external USB 3 drive that I use for TM.

After that mac mini boots I don't have any other issue.
Time machine disk works fine.

I try disk utility from recovery but didn't solve the issue

What can I try?
