What should I do if the BIOS does not see the hard drive?

A hard disk is the main device of your computer or laptop. There is an operating system on it that runs the machine. Also, all your data is stored there. Without it, it is impossible to imagine the work of electronic computers. Therefore, it is necessary to handle it carefully and carefully. After all, if this part is out of order you can lose all your valuable information.

However, it often happens that your BIOS does not see the hard drive. A number of factors influence this. First of all it is necessary to check the correct connection of the device to the motherboard. Pay attention to the power supply cord that comes from the power supply. If this is not the case, then try to connect your hard drive to another board controller. It also makes sense to replace the interface cable or power supply. These are rare cases, but they happen.

Another thing is that the BIOS does not see the hard drive because of insufficient power or a malfunction of your power supply. Therefore, it is worth paying attention to this nuance. In the event that the BIOS does not see the SATA hard drive, try changing the adapter from the IDE power cord . Do not forget that for the work of IDE-devices in your BIOS, support for such disks should be enabled.

Go to the advanced settings, where you select the configuration of the connected devices. Here you can activate the controller for the IDE hard drive. Do not forget to exit and save the changes. If your system already has hardware with a new SATA interface, but you still need to connect another hard drive with an IDE interface, the above procedure is also required.

Pay attention to the fact that on the necessary IDE- and SATA-devices you have the inscription ENABLED. The maximum allowed number of IDE devices can not be more than two per controller. If you have two connected, and the BIOS does not see the hard drive, try one to disconnect.

Also in my practice there were such devices that under any circumstances did not want to be displayed as subordinates. Another BIOS does not see the hard drive if you incorrectly installed the jumper, which is responsible for the mode of operation (master, slave and device, defined by the loop). Look to start, do you have it at all? If yes, then on the top of the disk there should be a circuit of correct inclusion.

These are the main problems that can arise with working hard drives. I want to draw your attention to the fact that very rarely the BIOS does not see the SATA hard drive. With these devices, there is almost never a problem. If you still encounter them, try to change the cable and go to the factory BIOS settings. If this did not help, you need to check the device itself.

I hope you understand what you need to pay attention first. As a rule, all these methods work and help. If you can not do anything and the device still refuses to work, contact a special service workshop. They will be able to determine the exact cause of the problem and, if possible, restore the hard drive you need. Under no circumstances should you try to disassemble it yourself.
