The hard disk is necessary for storing information on computers, the operating system is also installed on it, but if the laptop does not see the hard disk, then access to information will not be possible, because the operating system simply will not start. In fact, there can be many reasons, but if this is a problem in the settings, then you can easily solve this issue yourself.
What to do?
To solve the problem, you need to go into the BIOS, and already there you can exactly find out what the reason is. Especially if the laptop has ceased to see the hard drive, then you will be knocked out a certain message, why the operating system can not boot. The way that best suits you to fix this problem, you can choose only after you do the diagnostics. In the best case, you just need to make simple settings in the BIOS, but at worst you may need to replace the hard drive or even replace the motherboard. Of course, if you need to replace the motherboard, then it is recommended to contact the specialists, since it is difficult to replace this device in the laptop without skills, and you can damage some other important part.
Why?
So, as we said before, if the laptop does not see the hard drive, then it is necessary first to find out the reason, and we'll just talk about this right now. The reasons why the hard drive refuses to work may be different, for example, it is its immediate damage, the BIOS settings failed (this happens, but very rarely), and the controller malfunction. If you can determine that the problem has occurred in the hard disk itself, then it is most likely due to mechanical damage to the device, this can occur when falling, violently shaking, or striking. In fact, it's very easy to damage a hard disk. Of course, not many users can independently determine what is associated with the failure of the hard drive, it may be necessary to repair it, respectively, the device will need to be sent to a specialized service for a full diagnosis.
The laptop does not see the hard drive, what to do: details
The first thing you need to do is go to a special BIOS setup program. Go to these settings, you can immediately after starting the computer, you need to press the F2 or F4 key, but remember that for some other laptop models, other buttons can be used. In these settings, you can see for yourself whether the hard drive is determined or not. Also you will be able to view and, if necessary, change the settings for activation or hard disk connection. Sometimes the settings themselves can be knocked down, in which case you must manually re-create them. Immediately after switching to the BIOS, you will see a small table in which the connected devices are listed, this is a CD-ROM and a hard disk. If the laptop does not see the hard drive in the BIOS, then there is a high probability that it is damaged, and accordingly, it will need repair or even replacement on a new hard drive. However, do not immediately get frustrated, because the case can only be in the train, for example, it could disconnect or just fail. The worst case scenario is damage to the controller on the motherboard, in some cases it may be necessary to replace the motherboard. In order to test your hard drive, it will be enough to connect it to another laptop of an identical model. If after connecting to another device it is detected and working, then, most likely the problem is not in it, but in the motherboard or the cable.
Specialist help
If your laptop does not see the hard drive, and there is absolutely no skill in solving this issue, in this case only the service center where experts work will help you. But still, before contacting their services, try to look at the BIOS, whether it was determined or not. If the laptop does not see the hard drive, and you yourself have not been able to solve this problem, then you should be aware that in the service center the solution to this problem can be quite expensive.
