Ok if its a clicking noise, then the hard drive is busted. You need to save all your stuff from that drive and get a new one. Do NOT get a maxtor ,, they brake down.
Just like IBM back in the day making hard drives, churns out they were all defective stuff that broke down easy like yours. Soo IBM stopped making hard drives if you notice LOL.
I used to be in this business long time ago.
All I can say is, your drive is a gonner soo quickly backup stuff. The next click you hear might be the last one ,, if ya know what I mean. The device can be saved and your data but you send it into a company , and they charge like 800 bucks or soo.
Sorry you went thru this, but quickly get a new HD and copy over all your stuff, cuz that baby is about to blink its eyes to never open them again!!! GL
