I've been trying to get this resolved for over a year now. Parallels will block my Pegasus R4 from being recognized on my MBP. Parallels 7 Pegasus R4 Windows 7 64 Bit (Bootcamp) Currently, If I want to use my external hard/raid drive I have to shut down parallels, basically force quit, wait for the mac to pick up the raid, then restart parallels. This takes awhile even with I7. Is there any way to tell parallels to ignore all thunderbolt connections?
