Not a BIAB problem, but do any of you using BIAB with the Drum and RealTracks on a USB external drive sometimes have problems getting Windows 10 to recognize the disk? I keep that port powered, but this occasional nag of a problem seems to be happening more often. And, of course, if BIAB doesn't see that drive it defaults back to C: so I have to go back into Preferences and re-establish the path. Oh, it's on a pretty high end (at the time) Lenovo laptop for the past 4 years.
