Moving files to second internal harddrive, not copy
I have 2 harddrives in my 2010 MacBook Pro, running MacOS. One drive is an SSD and is my startup disk with minimal data and of course the OS on it. The 2nd drive (installed where the superdrive used to be) is a 1tb HDD I use only for data storage. If i want to move a file from my ssd to my hdd, it always wants to copy, instead of move (exactly like the behavior of putting files on an external harddrive). Is there a way to change this behavior for this hdd so that it moves the files by default instead of just copying them? My user has read&write permissions on the HDD and ive already done the "apple to enclosed items" AND checked the box for "ignore ownership on this volume" but don't havent help.
Any help here is appreciated.
MacBook Pro, macOS Sierra (10.12.1)
