A method for identifying hard disks connected to one or more ports of a computing device. The computing device comprises a controller. A first serial-number of each of the hard disks read by the controller is received. A second serial-number corresponding to each drive letter of the hard disk assigned by an operating system of the computing device is read. The first serial-number and the second serial-number is compared to determine associations between the drive letters and the hard disks. The associations are displayed on a display device connected to the computing device.
