Working on the last couple of weeks on the newer range (ST3750640AS) of Seagate Bigger hard disks have made us a bit weary on the design and performance. We have found an increase in the need for Seagate data recovery of these drives. The main problems that we have found is that if these drives get the slightest bump or knock, whilst running and working, they tend to suffer from “stiction” (when the head stack gets stuck to the platters) which prevents these enormous weighted platters to stop spinning rendering the drive useless. If this does occur, there is a slight ticking sound that will emit from the hard disk.
