Is it safe to access the same virtual drive (data only, no OS installed) from multiple Parallels virtual machines at the same time? For a bit of extra security I have the data accessed by my XP virtual machine installed in a second virtual drive that only contains data. I often have more than one version of Windows open at the same time for testing, and it would save space if they could all access the same data virtual drive, instead of each having their own drives. I'm just a little hesitant to do this before I'm absolutely sure that it's safe...
