Mac Mini wakes every minute with screen sharing on. 10.9.2

Anyone have any suggestions to fix this?

Not sure when it started, possibly after the 10.9.2 upgrade.

About every 72 or 73 seconds my mac mini (2011) wakes up the external disk drive attached.

I narrowed it down to where:

IT ONLY HAPPENS WITH SCREEN SHARING ENABLED.

Using command: syslog |grep -i "Wake reason"

Mar 5 16:38:22 Mac-Mini kernel[0] <Debug>: Wake reason: ?

Mar 5 16:39:35 Mac-Mini kernel[0] <Debug>: Wake reason: ?

Mar 5 16:40:48 Mac-Mini kernel[0] <Debug>: Wake reason: ?

But the screen DOES NOT come on, just the drives spin up.

Soo Annoying, It will kill my external drive stopping and starting every minute.

Turning off screen sharing is the work around but why?
