When does Windows not see the hard drive?

What should I do if your Windows does not see the hard drive? Let's deal with this problem together. A common cause is the incorrect settings in the BIOS of the priority of device downloads. So that you understand what I mean by this, imagine what you put in the settings so that at first the computer accesses the ci-rum and only then to the hard disk.

After that, you ran or viewed a disk with photos in Windows and forgot to remove it. The next time you turn on the computer, it accesses this media. Since it is not bootable, it is possible that it is for this reason that you do not determine the hard drive. In this case, you need to pull out the compact and try again.

If you have the second drive in the download queue, and there is no laser disk in the si-rum or USB flash drives in the USB ports, change the BIOS settings in BIOS settings so that your hard drive on which the operating system is written is the first in the queue Launch. After that, you need to save the settings and reboot the computer.

You did it all, but the hard disk is not detected as before, then we continue to search for the cause. Go into your BIOS settings and see if your computer sees it from there. If not, open the system installer and check the correctness and reliability of the connections to the motherboard and the power supply. If possible, try connecting it to another computer, or using another cable. When it comes to devices with IDE-interface, make sure that the BIOS is allowed to use such devices.

The next reason that Windows does not see the hard drive can be covered in error with the installation of a special jumper that changes the modes of your hard drive from the master to the slave. Make sure the correctness of its position, drawing on the scheme, which, as a rule, is drawn on the label at the top.

In my practice, I came across an extremely unusual reason, because of which Windows does not see the hard drive. After I installed the necessary parameters for myself in the BIOS, I saved them and rebooted the computer, they did not take effect and remained at the level they were before my settings. I repeated the above procedure, but I did not get the desired result.

After some time to find out the reason, it still showed up. It turned out that a power supply was installed in the CMOS chip. As soon as I replaced it, the changes were preserved after the first attempt. So, if you can not solve your problem in other ways, try replacing the battery.

I think you now have an idea of why it happens that Windows does not see the hard drive. Although we have not considered everything. But the rest is the work of specialists. If you tried all possible methods, but did not come to anything, entrust this to a qualified professional, so as not to aggravate the situation. These people have the necessary equipment and experience, with which they will correct your misfortune. If it does not work out even for them, most likely, you have to buy yourself a new hard drive.
