My book 3tb doesn't mount

JUSTopened box and hooked up but is not recognized by my imac 10.6. does not show up in disc utility. ???

Hello,

As a recommendation, please check the physical connections on the unit. Make sure that the drive is connected to the wall power outlet and test the drive using a different computer.

What’s the model number of the unit?

Hi bobkasp,

In addition to ERmorel’s suggestions, a lot of the newer Mac’s don’t show direct attached drives on the desktop by default. Check to see if the drive shows up in Device Manager or Finder. If you want to enable the ability for USB drives to show up on the desktop, you can navigate to: Finder > Preferences and then under “Show these items on the Desktop” makes sure that there is a check next to “External Disks”.
