Go to this page http://datacent.com/hard_drive_sounds.php Down to Maxtor and click on the second from the top or second down play button " Maxtor drive with bad heads making steady clicking/knocking sound." This is exactly the sound my hard drive makes. Thing is it only does it randomly. Go for weeks or even months with nothing then it will start. I think I need to change it out before total failure. When it does start to click it will usually crash and give me a system dump screen. I am going to need help. What is the best free program to clone a drive? I am going to need to be walked through the steps. I have read up a little on Google but it is a little confusing. Will it be a simple plug in new drive, clone old drive to new drive, remove old drive and good to go operation? If anyone knows a website that explains it clearly please post it.
