Hard to believe no one has more up to date info on what is safe given drives are so large now and file system improvements. I'd think having a TB or two would be plenty, regardless of percentage, but not real sure. Don't want to risk data testing the theory either. Update: The new drive came in. It passed all the tests and is online. dfc looks like this now for Data. %USED USED AVAILABLE TOTAL MOUNTED ON 66.4% 37.1T 18.8T 55.9T /home/dale/Desktop/Data May have to start adding two drives at a time. o_O 18Tb and larger drives are to pricey still.
