3.2 Unmounting Drives

For the safe removal of your drive and to ensure that no data is lost, always eject or 

unmount the corresponding disk(s) from your operating system before powering off. 

You can use the methods described below to safely unmount your disk(s).

Mac OS X:

Each of the methods below will produce the same result.

•  Drag the icon for the disk you wish to unmount to the trash can. 
•  Right-click the disk icon on the desktop, then click ‘Eject’.
•  Highlight the disk on your Desktop and press Command-E.

Windows:

1.  Go to the System Tray (located in the lower right corner of your screen). Click on the 

‘Eject’ icon (a small green arrow over a hardware image).

2.  A message will appear, detailing the devices that the “Eject” icon controls, i.e., ‘Safely 

remove...’ Click on this prompt.

3.  You will then see a message that says, ‘Safe to Remove Hardware.’ It is now safe to 

disconnect the Mercury Elite Pro Dual from the computer.

3.3 Troubleshooting

Many problems can be traced to power or connectivity issues. Begin 

troubleshooting by verifying that the Rack Pro mini-SAS is connected to power. If 

connected to a power strip, make sure that it is switched on and that there are no 

bad outlets on the strip. If power issues persist try plugging the Rack Pro directly 

into an active wall outlet.

It is also important to verify that your mini-SAS cable is fully plugged into the 

computer and Rack Pro. If the cable connections are snug and the Rack Pro is still 

not working properly, please see Section 3.5 to contact Technical Support.
