I replaced a 3200GB HitachiI  Deskstar drive in my  MacAlly model PHR-S100SUA FireWire/USB 2.0 enclosure with a brand new seagate barracuda 1 TB drive.


However it does not show up on the desktop of my iMac 3.06 GHz Intel OS X version 10.9.3.


The 320 GB drive worked perfectly but i needed more GB's storage space.


What do i do to mount the Seagate. Disk Utility and Disk Warrior do not "see" it.


Please help. Please note that this is my first time ever for doing this. I thought it was a simple unplug/remove then install and plug in the power and data cords for the new drive.
