Sometimes it happens that just yesterday a well-functioning computer for no apparent reason starts to crash. It is especially unpleasant if the failures are associated with a storage medium - a hard drive. If the system does not display a hard disk, then the owner of such a computer begins to panic remember how, it turns out, a lot of valuable digital data was saved by the device. Well, really, a person begins to value something only when he loses.
In fact, the message that the hard drive is not displayed is not a reason to immediately run to the computer parts store for a replacement and ring up service centers, being interested in the possibility of recovering information. Very often you can "repair" a failed device yourself - quite a bit of free time and accuracy. Although, of course, a lot depends on the reason why the system does not display a hard disk.
Before we look at ways to restore performance, we’ll note two important points. Sometimes you may see a message on the forums that the seagate hard drive is more reliable. Who does not know - this is the name of the manufacturer. Or similar: the most reliable is a wd, or samsung, or some other hard drive. These are completely baseless statements.
No manufacturer is interested in producing low-quality goods, because this means a potential loss of confidence on the part of buyers. Therefore, if, nevertheless, the hard disk is not displayed, then in the last turn it should be associated with the manufacturer.
And the second one. If during power-up, extraneous clicks are heard from the hard drive (tapping, the engine spins up and slows down), then the probability of self-recovery is, alas, low.
So, if the message Disk Boot Failure appears on the screen when you turn on the computer, then loading from such a disk is not possible. The computer simply "does not see" it. We press the Reset button on the case of the system unit and on the first screen with the image we often click Delete (Del). Thus we get into the BIOS. Here in the Standart section we are looking for disk settings (Primary Master, etc.). We make sure that in points there is no ban on working with the device (Enabled must be installed).
The next step (all of them are performed when the computer is powered off) is to check the loops. The way to fix modern SATA wires is significantly inferior to the time-tested IDE (PATA). Two loops are connected to the disk - power from the unit and interface from the motherboard. Disconnect the second from the drive and the board and reconnect. We check the performance. If a positive result
no, then we replace the loop with a new one and check. Due to a poor-quality contact group in the connector, the electrical contact is often broken and the disk does not appear. Replacing the loop eliminates this problem. It is useful to reconnect the power cord.
You can also connect a SATA cable to another free connector on the motherboard.
Do not forget that the best solution is to check the hard drive on another computer.
Please note that sometimes problems arise when trying to connect a new drive to an old motherboard. For example, for normal operation of a hard drive with a volume of more than 2 TB, a system with UEFI support is required.
