I've had my vista Parallels running for a while now and have been slowly moving data from my external HDD, slowly being the key word there! If I plug the drive in another vista PC the data moves on and off it at a decent speed, yet from within parallels it's dire! Same is true for memory sticks, got a 1gb kingston, which again, in a friends dell copying data to and from is quick in the VM, took 15 mins to copy 400mb! Running the latest build of parallels and Mac OS, any hidden tweaks etc that might help?
