[ubuntu] USB and external HD not mounting

view full story

http://ubuntuforums.org – I have a western Digital USB HD that when connected the light comes on the drive and the drive makes a repeated dull clicking noise and never lets me view the drive. I connect the same drive and USB cable to another PC running 9.04 that works perfect on. I can connect my Black berry to the very same USB port and cable it works fine. I also put a new USB card in the PC and still same issue. Any suggestions? (Hardware)
