Choose one of the following:

• Connect it to my Mac . New external devices are automatically available for use with Mac OS X applications.
• Connect it to the active virtual machine . New external devices are automatically available for use with Windows programs. If Windows isn't running, the external device is connected to Mac OS X.
• Ask me what to do . Each time you connect an external device, you're prompted to choose whether you want to connect the device to Windows or the Mac.

Set a Particular External Device to Always Be Used With Mac OS X or Windows

If you know you always want a particular external device to be available to either Mac OS X or Windows, you can set it to do so by following the instructions below. The device must already have been connected to your Mac at least once.

1. Click the Add (+) button towards the bottom of the window.
2. Select the device from the list.
3. Double-click the word (either Computer or some form of Windows ) in the Connect To column. The word becomes a pop-up menu.
4. Do one of the following:
   • To set the device to always be available to Mac OS X applications, choose Computer from the menu.
   • To set the device to always be available to Windows programs, choose Windows from the menu.

To remove an existing assignment, so that the device no longer automatically connects to Mac OS X or Windows, select the device in the External Device column and click the Remove (-) button.

Important: To be able to use an external device with Windows programs, you may need to install Windows drivers for the device. Typically you can download drivers from the manufacturer's website.

Mount Windows-connected external NTFS drives to Mac
