The computer does not see the external hard drive. What to do?

Many users at least once during the use of computers faced such an unpleasant situation, when it would seem that a new computer does not see an external hard drive. It does not matter, a flash drive is a couple of gigabytes or a hard drive per terabyte. Consider the common reasons why this happens.

The first reason

The external storage device is not connected correctly. This situation is characterized by the fact that the system does not react at all to the connection of an external device to it. Most of these devices have diode indicators, which makes it possible to eliminate the possibility of their malfunction. That is, if the external hard drive lamp is on, the device is working properly. In case you have connected an external drive to the front panel of your system unit, try switching it to the back, main panel of the unit. This eliminates the possibility of a non-working condition of the extension cables that extend to the front panel.

The second reason

But in just two minutes it is determined, however, a message appears about the malfunction during the installation. Happens, "pops up" a message that the device could not be identified. The reason may be a banal food shortage. The way out of the situation will be to connect an external drive directly, that is, behind the system unit. Many noted improvements to the work after reinstalling the drivers of the motherboard. In order to find out what your motherboard model is, download a program that shows all the motherboards installed in the system. An example is Everest.

Third reason

In this case, it is necessary to scan the device that connects to the system, a reliable anti-virus program with an updated database. It is also possible that your system installed on the computer does not see the external hard drive because the user forgot to connect it to the power source. There are such models (concerns especially capacious storage devices), which, in addition to the USB-socket, have a hole for power connection. Check if this is available, connect the hard drive to the network.

The main one is that the external drive has a NFTS system, which the mac uses only for reading. Therefore, it is necessary to change the file system of the external drive - and the problem will disappear.

To sum it up, let's say that the problem when an installed system does not see an external hard drive is solved quite simply. The main thing is to pinpoint the cause and act according to the above instructions. If after that you will not be able to connect it, contact a specialist.
