Your data will then be re installed onto the new hard disk. The brand new hard disk will be installed and the same Mac OS system installed onto the new hard disk. If the hard disk does need to be replaced and it is possible the engineers will backup your data stored on the faulty hard disk. So the engineers will know exactly if the hard disk is healthy or needs to be replaced. This will report the status of the drive as healthy, caution (meaning failure is iminent) or Bad. Our engineers will run diagnostics tests at your Imac to confirm the health status of your internal hard disk.Īll hard disks have SMART technology, which is basically a system within the hard disk itself that constantly checks the status of the hard disk, this gives the temperature of the hard disk, bad sector or read / write errors and seek errors.
