I want to copy the files from a USB 3.0 8TB mirrored drive pair (hardware mirror, not Storage Spaces or other software) to a single 12TB USB 3.0 drive, reformat the mirrored pair, then copy everything back, in order of largest file to smallest.
Why? Because the files are an extremely fragmented mess and defraggers tell me it'll take a very long time to sort the mess. I know it'll take 2~3 maybe 4 days to do the copy then copy back.
The fastest defragger I've tried so far is the old MyDefrag. I could let that chew on the mirror pair for as long as it takes - except it has that pointless translucent window that tells what the different colours mean. That window cannot be closed or minimized. I figured I'll just use Task View, launch a second desktop then run MyDefrag there. NOPE! That un-closable window shows on *both desktops*. That's some Microsoft Clippy level of horrible, annoying software design. Since MyDefrag's author quit on it back in 2009, that "feature" isn't going to be fixed.
I'm tempted to temp setup a second monitor to see if that "helpful" window duplicates onto both physical screens.
