I have the option set to "ask me what to do" when a USB device is detected. If the HD is plugged in while running MacOS and I turn on my virtual machine, parallels will not recognize it. (I am running win2000 pro). If I plug it in after win2000 is running, then it will ask me to allow it, I click yes, then it quickly tells me that I removed a device before it was properly put away. WTF? any thoughts? Incidentally, I have tried to install new hardware, using the installation wizard and it detects nothing. I checked with Seagate website to see if "freeagent desktop" HD is compatible with win2000 pro, and it is. No drivers came with the product. I had no problem with Parallels recognizing it when I was running windows xp pro.
