Seagate free agent goflex external ITB external hard disk is not detected by any computer or laptop. And it makes clicking sound for 2min when we connect to the system . So please help me to solve this problem.
The clicking sound is bad news. The read/write heads are either jammed against the platters and are trying to get free, or the drive's electronics are faulty.
Neither problem can be fixed. You need a new external hard drive.
