My 1st 1TB drive cost me $300. This 10TB not much more. When a drive has become old, or dying, my logic says might as well go larger. I think I'm still hopeful that it was some kind of glitch. That windows is merely causing something wonky with the 6TB. I want to be close to it for several hours, while it transfers. I have a road trip today, and a birthday tomorrow. So Monday it is lol Plan to reinstall windows, and go brand new cables. So as to eliminate any other possibility.
