Disturbing of the connection of the drive with a road recording device can be an unpleasant discovery during any situation that requires video software. The reasons why the DVR does not see a hard disk, and how to deal with them, we will look at the current article.
Why the video recorder does not define HDD
As well as any device to which you can connect a hard disk, the video recorder may not catch it one of four reasons:- Disability of the drive;
- SATA-cable damage;
- Defect of the DVR board;
- Insufficient power supply power.
That is, initially software prerequisites for the impossibility of determining the drive from the registrar, and therefore we will mainly look at the state of its hardware and check the HDD, but not more.
Cause 1: Problems with a hard disk
Let's start with the consideration of the drive itself, because it is impossible to throw off the fact that it has been trite developed resource and / or he broke. Therefore, you should disconnect the hard disk from the registrar and check it on any computer in this way:
- Disconnect the HDD by removing the SATA cable and power cable from it.
- Remove the bolts on the back of the device, with which the hard disk is attached to the video recorder.
- Now connect the storage device to the stationary computer. If the HDD has been successfully determined by the computer, a number of diagnostic measures should be made, they are dedicated to a special article on the reference below.
- When the hard drive is not determined with the go, then, most likely, it is irretrievably polnean. The only thing that can be done with it is to attribute to the service center, where experts will conduct a procedure for extracting information if you need. However, before this, it is further important to make sure that the SATA-cable of the registrar works without failures. Disconnect the wire from the DVR board and connect the drive to your PC through it. If HDD has not started, then the problem is in the connecting element. Find it to the replacement, and the device will start writing the video to the same disk.

Cause 2: Problems with power supply
A more popular reason for the loss of contact of the hard disk and the DVR is the lack of power supply, due to the fulfillment of the failed or the capped power supply. If earlier the drive worked correctly and without errors worked in the DVR, and then you successfully checked it and the SATA cable for performance through the PC, which means the problem is most likely in the power supply. It is worth purchasing a new BP, preferably increased power, transforming 12 volts of 5 amps.
Such a power supply will be enough for uninterrupted power supply of the registrar and drive, and you will forget that one device does not see the second or HDD turns off at an inappropriate moment. In that situation, if it did not help, it means that something is wrong in the DVR card itself, maybe even with the program part, but this problem is guaranteed to solve only in the service center.
In the above material, we looked at why the DVR does not see a hard disk. It can be a breakdown of hard drive or SATA cable, lack of nutrition or the problem of the registrar board.
