My new harddisk has some clicking sound after around one week after i bought it. It just suddenly hang the machine that day. Right afterthat, I am not able to boot up the machine if the harddisk is installed.
I realized that the harddisk is not able to start up. Whenever it approaching it's maximum turning speed, it's start to have clicking sound and hang the whole machine.
I would want to find a way to recover around 50G of data in the harddisk.
