The hard disk drive has been enhanced into a new model known as the Serial ATA or the SATA hard disks drive. These SATA drives have started to replace the usual ATA hard disk drives. As the technology changes new modifications and updations are regularly added to any of the existing device. In the range of the personal computer systems the hard disk drives that are popularly being used are usually the Serial ATA hard disk drives. The SATA hard disk drives are popularly used in the mid-range computer system models as well as the high end models. In comparison with the usual IDE or the ATA hard disk the physical dimensionality the data cable is much smaller and wider. But at the same time the power cable is slightly thinner. If there is any problem in relation with the SATA hard disk drives then it may be due to the some of the reasons that occur commonly. They are explained below.

The hard disk drive may not be visible or is not shown in the system configuration. The main reason or the major possibility is that the power cable connections or the data cable connections may not be connected properly to the hard disk drive. In such a situation the data cables and the power cables should be reconnected again. But before doing so, be assured that the system is properly shut down. The other possibility is that the cables may be loosely connected or may not be connected at all.

Another reason for the hard disk drive that it is not shown in the computer configuration is that it may not be properly connected to the SATA host adapter. There is usually an adapter in the motherboard to which the hard disk drive is connected. It may also be the possibility that there is no add-on card there in the motherboard. In case if the hard disk is not connected appropriately to the interface; then the possibility is also that it may not receive the command to spin up at the time when the computer system boots up or starts up. The cable connector of the SATA cable may be keyed. This prevents the connections that are reversed; but in the case of the original SATA connectors it is also possible.

The situation in which there is damage to the signal or the power cable may also result in causing the failure of the SATA hard disk drive. In such a situation it is possible to replace the signal cables of the SATA. The signal cables of the SATA may have been folded or even creased. The power cables or the signal cables of the SATA hard disk drive may have developed the cracks or may also have been torn. The insulation is not proper or the cables may have a torn connector.

It is important to note that in any case the SATA data cable should never be folded. The folding of the data cable or the signal wires result in the damage to the small data cables and signal wires that are present inside the outer jacket. Also the other possibilities include that the host adapter of the SATA may have been disabled on the mother board’s system BIOS.

The major reason of non detection or any trouble with the SATA hard disk drive is the improper installation of the device driver software. The device driver software may also have been corrupted.
