So here is a good one. Used Samsung Magician to go to a EVO 860 drive and my signal went down to 66% from 92%. Thinking I'm losing it I switch the boot up drives back and sure enough back to 92% on the HDD. Found a post with google about if its near the card blah blah it can cause issues. Thing is this drive has been in there for a bit over a week just idling before I made the jump. Ideas!? EDIT: This is under Windows 7 x64.
