"No media drives available" when attempting import

Hi-

MC 8.6.4, OSX 10.11.6 running on an 8-core trashcan Mac Pro. Media drive is a G-SPEED Studio XL 48TB RAID.

Can't import media, can only link. Trying to import gives the "No media drives available" message and will allow shot logs only.

Dragging to the bin works.

Linking is fine, previously imported media is fine, import settings are correct, drive filtering on or off makes no difference.

I can make the problem go away by quitting MC, unmounting the media drive, launching MC and then mounting the drive. It will then import correctly until the next relaunch. Kind of a pain.

Any thoughts?

Thanks,

Chyld King
