Bios does not recognize ide hard drive. Bios does not see the hard drive - solution to the problem. Incorrect installation of jumpers on the drive housing

Hard drive is not detected in BIOS For many reasons, if you connected the hard drive yourself, you need to first check whether you have connected the interface cable and power cable correctly. Let's first look at the interface for connecting an outdated IDE hard drive (parallel interface for connecting drives), but much of what will be said is also suitable for SATA hard drives. Friends, if this article does not help you, try or.

From the power supply there are power cables to motherboard, hard drives, we are interested in the power cable of the hard drive, it ends in a connector that fits into a connector on the hard drive that looks like a plug; if connected incorrectly, the hard drive activity indicator on the system unit will be constantly on. It should connect freely, without the use of force. The interface cable for connecting the hard drive has a special key, the photo shows the cable, one contact is missing on it, and below the controller from the motherboard there it is also missing, as if broken, or in other words, there is a special protrusion on the cable, and on the IDE connector in the motherboard The board has a special slot.

Pay attention to the interface power cable on the left; the far right conductor is marked in red, which points to the hard drive power connector located on the right, this tells us that everything is connected correctly.

Hard drive is not detected in BIOS

Connected correctly and HDD not defined doesn't matter.

We try to connect our hard drive to another SATA or IDE controller (connector) on the motherboard, replacing the SATA interface cable also sometimes solves the problem, try also using a different power supply cable.
Do not forget that sometimes, due to low power or , your second connected hard drive will not be detected, and problems may also arise with the first one.
If you are using IDE-SATA adapters, try replacing them.

About outdated IDE hard drives, know one thing, no matter what modern motherboard you have, if the manufacturer left at least one IDE controller on it, and this usually happens, then such a hard drive should work in your system unit.
Next, we look to see if the IDE controller itself is enabled in the BIOS, please note this Ami BIOS you may have an Award BIOS, but the meaning is the same.

Many users quite often encounter a situation where the BIOS cannot detect the hard drive. The BIOS is responsible for the order in which hardware starts up when the computer starts and maintains the functionality of all computer components. And if the system does not detect installed devices, first of all, go to the BIOS and check whether they are enabled or not.

The problem can be caused by failures in both hardware and program levels. When the user turns on the computer and during boot sees the following message “DISK BOOT FAILURE. INSERT SYSTEM DISK AND PRESS ENTER. No bootadle device - insert boot disk and press any key", this means that the system has not identified the main hard drive from which the boot starts, or the boot sectors of this device are damaged.

First, let's find out what caused this problem - damage hard drive or a malfunction at the software level.

The second case is not so critical; most likely, the damage to the boot sectors was caused by malware or a virus, as a result of which the system did not detect the boot files operating system and issued the above warning.

We go into the BIOS settings, and to do this, when starting the computer, use the Delete or F2 keys. The main BIOS menu displays information about all connected hard drives on your computer. If you find a problem there hard drive, then the problem is most likely caused by a software glitch due to corruption of the OS boot files.

First, let's test the hard drive for bad sectors. Scanning can be done, for example, using the Victoria program. The point is that damage system files not only viruses, but also bad sectors in the boot part of the hard drive. To check the hard drive we need boot disk or a flash drive with the Victoria program. For full diagnostics, you should also add an anti-virus scanner, for example, DR Web LiveDisk or Kaspersky Rescue Disk.

If during the check it turns out that the surface of the drive is not damaged, and malware was detected during an antivirus scan, then it is imperative to reinstall the operating system.
It is highly recommended that before installing a new OS, you do a full scan of your hard drive for viruses.

Mechanical damage to the hard drive

If, with the appearance of such a line, you hear noises or tapping of the hard drive, while in the BIOS it is displayed in the list of connected devices, the malfunction in this case is associated with mechanical damage to its parts or failure of the controller.

You will not be able to extract information from a damaged HDD on your own at home; all attempts to fix it can aggravate the situation even more, and you will lose forever important files. To recover data from a damaged hard drive, you should contact service center.

What to do if the disk is not detected in the BIOS?

If the BIOS does not see the hard drive, then the malfunction is caused by a hardware failure. Let us consider in detail what to do and why this situation may arise.

First, we check the interface cable (IDE, SATA) through which the hard drive is connected to the computer’s motherboard, as well as the power cable.

Perhaps after cleaning the computer or installing, for example, brackets random access memory, you accidentally broke contacts. If everything is in order with the contacts, use a different interface cable and, therefore, a power cable to check.

The next link with which problems may arise is the motherboard. Checking it is quite simple - you should connect another known working hard drive. Then go to the BIOS and see if it appears. If the BIOS does not detect the hard drive, the motherboard is faulty. Another option is that the IDE or SATA slot on the motherboard has failed, for example, as a result of a microcrack that has appeared due to excessive force when connecting the cable. This is especially true for IDE connectors. In this case, connect the cable to a different slot.

Problems connecting a second hard drive

Note the IDE hard drive connector, which includes four pairs of pins located between the cable and power connectors. It is used to set the hard drive priority, which is set using a special jumper.

If the hard drive is the main one and the computer is booted from it, place the jumper in the Master position. In the case when you add a second hard drive, make it a slave by setting the jumper to the Slave position. If you have not done this, and two disks are used as primary disks, a device conflict will arise, as a result of which the BIOS will not recognize one of them. This situation is typical for hard drives with IDE interface. To prevent this from happening and you cannot find out the position of the Slave, remove the jumper from the second disk altogether.

When you hook second hard The IDE disk is on the same cable as the main one; a situation may also arise when the BIOS does not see it. If this happens, connect it separately to another connector, through a second cable.

Problems connecting a SATA hard drive

First, we check the contacts and serviceability of the SATA interface cable by replacing it. If everything is in order, go to the BIOS. Here we check the ACHI status, try to switch it to another mode and see if the problematic SATA hard drive appears in the list of connected ones. If it does not appear, reset the BIOS settings using the Clear CMOS jumper on the computer motherboard.

Below is a list of the main problems due to which BIOS does not recognize a SATA hard drive. To find out the true cause of the malfunction, you need to carry out sequential diagnostics of all interconnected components of the computer to determine if they are working properly.

The hard drive is not set as enabled in the BIOS.
Serial ATA drivers are installed incorrectly or not installed at all.
The data cable is damaged or not connected.
The disk drive does not spin.
The jumpers on the drive housing are set incorrectly.
The hard drive itself is faulty.

First you need to make sure that the device you are testing is enabled in the BIOS. To do this, you need to enter the settings - at the very beginning of the operating system startup, press the F2 or Del key. Depending on the modification of the system, there may be different options. What exactly do you need to click to enter the BIOS settings? A message appears briefly at the bottom of the screen when you turn on the computer. If you miss the period, you will have to turn off the computer again and wait until you enter the settings.

Find the hard drive that is not detected on one of the settings screens and look at what is written next to it. Automatic detection must be specified. If it says Off. (Off) you need to switch to automatic detection. This problem is typical in cases where a newly installed hard drive with a SATA connection is not detected.

Motherboard drivers not loaded

Problems with driver installation most often occur in cases where Windows OS is installed on a disk drive that is used as the main boot drive. Then the Bios does not see the SATA hard drive due to problems with the drivers.

To correctly download and install drivers, perform the following manipulations:

Load the Windows distribution into the DVD drive tray. After this, disconnect the computer from the power supply.
Insert the SATA hard drive and connect it. Turn on your computer.
During the installation process, you will need to press the F6 key at the appropriate moment to start the driver installation process. During the normal course of the system installation, a screen will briefly appear indicating that in order for the system to install normally, you must download missing drivers: “Press F6 if you need to install a 3rd party driver.” Try not to miss the moment, otherwise you will have to start all over again.
After a while, an interface will appear to download drivers for SATA controller. Press the S key to continue installation.
To download the drivers, you will need disks with installers; this must be found and downloaded in advance on the Internet, on the website of the manufacturer of the motherboard that is installed on your computer.

Data cable fault

Open system unit and carefully inspect the cables connected to the motherboard and hard drive. If there are visible mechanical damage This is exactly the problem. Data cables are easily bent and broken, which leads to a lack of contacts in the connections. It is advisable to check the cable by replacing it with a known working analogue.

Seagate technical services note that for normal operation of the devices, the length of the SATA cable does not exceed one meter. SATA cables often simply fall out of the connectors due to vibration of the computer during operation. Check the reliability of the cable connection to the SATA ports.

When connecting loops, be guided by the following conditions:

The blue connector must connect to the motherboard controller.
The gray connector is used to connect a Slave – an auxiliary hard drive.
The black connector is for the Master – the main drive.

If the cable assignment order is mixed up, it confuses the BIOS and leads to device identification errors.

The disk does not rotate

The hard drive will not be found if it is not receiving power and is not spinning. It is impossible to see the rotation of the disk externally; one can only rely on indirect signs.

With the power off, open the system unit, then turn on the computer and listen. Taking precautions, try touching the side wall of the hard drive. If vibration is felt, the disk is rotating.

If nothing is clear, try turning the drive's power cable on and off and comparing the sound. To check the functionality of the power cable, connect it to a DVD drive, where you can accurately see whether the disc is spinning or not.

It is also useful to check whether the installed power supply supplies sufficient power? It is quite possible that as the system unit is upgraded, power consumption has increased significantly and now there is simply not enough current to maintain the required performance of the equipment.

To make sure that the device being tested is working properly, remove it from the system unit being tested and install it on a known-good computer. If it doesn’t work, the hard drive itself is faulty.

The BIOS tools include a function for testing connected drives for functionality. Run the test and see the results. If any disk is faulty, it will be clear after the test.

Incorrect installation of jumpers on the drive housing

First you need to check whether the jumpers on the Master-Slave attribute are correctly distributed. If both devices have the same settings, the BIOS will not be able to detect them correctly.

A diagram of the correct location of jumpers is drawn on the drive housings. Set them according to the required priority for selecting disks in the BIOS.

Hard drives today occupy a leading position in the long-term data storage industry as devices that have high capacity, low price and high reliability and speed characteristics. Despite the fact that technologies in the field solid state drives progressed not at the same speed as other areas in the field of computer hardware (processor, memory, etc.) nevertheless, hard disks significantly superior to their predecessors in capacity and speed.

Over the past ten years, great results have been achieved in the field of upgrading HDD parameters, which were developed thanks to the transition to another data transfer technology between hard drive and the motherboard – serial interface Serial ATA (SATA). Today, SATA hard drives have almost replaced IDE hard drives from sale due to their performance. In addition, connecting drives with a SATA interface to the motherboard is much easier and faster compared to IDE hard drives.

Users of SATA hard drives often encounter a problem where the hard drive is not recognized by Windows. How to fix the situation when Windows 10 does not see the second hard drive is written in the article at the link. In this article we will show you how to fix the problem where the BIOS does not see the hard drive. In this situation, the hard drive cannot be used to save data; In addition, the operating system cannot be loaded.

For the most part, the reasons why the BIOS does not see the hard drive can be divided into three groups:

Hard drive defect
No power to hard drive
Poor SATA connection to motherboard/hard drive or faulty SATA cable
Incorrect BIOS options setting

Let's consider all situations when the BIOS does not see the hard drive.

Hard drive defect

In general, it is not easy to damage a hard drive by accident. When a computer or laptop does not see the HDD, the first thing you need to do is look to see if there is external damage on it. First you need to check the jumpers, because their failure is the most common reason, in which the BIOS does not see the hard drive. The jumpers are located on the back of the hard drive. What defects can you see with your own eyes: the jumper is bent, partially broken or completely fallen off, oxidized.

IN in this case If you just bought the hard drive on your computer, you need to take it back to the store to replace it with another one. If the media has been in use for a long time, you will have to buy a new one yourself.

If the contacts of the SATA connector are oxidized, then in this case you need to treat the jumpers with a solution that gets rid of rust (lemon, soda, vinegar). You can read more in this article.

In some cases, when examining the surface, physical defects are revealed. Such defects include:

Defects of microcircuits on an open hard drive board;
Damage to the HDD casing;
Destruction of hard drive parts (note: the motor is broken).

If the above problems are present, it is necessary to assess the completeness of all damage. You can evaluate it yourself or from those who know more. If the hard drive can be repaired, then it makes sense to take it to a service center. Otherwise, it's easier to buy a new one.

No power to hard drive

The BIOS sees the hard drive if there is no power to it. You can determine whether there is power on the hard drive by such a sign as rotation. Since the disk itself is located in the case, it is impossible to see the rotation; you have to look at indirect signs.

With the computer turned off, open the case of the system unit, and then turn on the power and listen to the rotation of the hard drive. You can try to touch the hard drive case. If there is vibration, the disk rotates.

The power cable for the hard drive comes from the power supply and you need to check the connection of this cable to the hard drive. If the contact is bad, you need to remove the cable from the connector and reinsert it more tightly. Then check again whether the computer sees the HDD.

Problems with SATA cable

To check the SATA cables, you need to open the system unit and look at those connected to system board and hard drive cables. If there are visible defects, then it is worth replacing the SATA cable. SATA cables can become bent or broken, resulting in the hard drive not being visible to the computer. If there is no visible damage to the data cable, then you need to check how tightly the SATA cable is connected to the hard drive connectors and the motherboard.

Incorrect BIOS options setting

Often the BIOS does not see the hard drive due to incorrect settings. This may be due to several reasons:

Power outages
Viruses in the operating system
Connecting new components to the motherboard
Human factor

To perform diagnostics when you turn on your computer, you need to go to BIOS menu. To get into the BIOS settings, you must press the F2 or Del keys at the very beginning of booting the computer, depending on the motherboard manufacturer. Typically, keyboard shortcuts are specified when the system starts. When entering the BIOS, we check whether the functionality for detecting the hard drive is enabled. To do this, select Integrated Peripherals from the menu and find the Onboard IDE Controller section. Press Enter and see that opposite this section there are two inscriptions Enabled (enabled) and Disabled (disabled). We check that it is Enabled. Then we save the configuration and reboot.

If this action did not help, then you can try resetting the BIOS settings. To do this, turn off the computer or laptop, disassemble it and then look for a round silver battery on the system board. We take it out and wait about 30 minutes. Then we insert it back and try to start the computer again.

The wonderful times when no hard drives simply existed have long since sunk into oblivion. Development high technology What makes it different from others is that it does not obey general laws, but rushes forward like a stratospheric rocket.

Tape drive mechanisms may have failed more often than modern ones magnetic disks, but the reasons for their breakdowns were much more understandable. Although... what are we saying? No, we are not asking everyone to go back to the Stone Age. God forbid! We simply present some comparisons, which, according to certain parameters, do not always turn out to be in favor of modern technology.

So, your hard drive has broken down or you suspect that the failure lies precisely in it - in the inadequate operation of this complex and obscure device. You are saved if there is another PC nearby that sees its own hard drive. Just swap these two drives and make sure that the other machine recognizes it as working.

If this is the case, then the problem lies in the incorrect settings of your system. If the second computer doesn’t see your unfortunate screw, it means it’s really faulty, and at the very least you need to take it in for repairs. As a maximum, simply throw it away and replace it with a new one if its surface did not contain some critical data.

We will assume that the screw was detected by another computer and the essence of the problem should be looked for in the settings. It happens that the BIOS ( Basic system input-output) does not recognize this or that hardware. In this case, it is usually not recognized by Windows itself. Let's see this using the example of a hard drive.

BIOS does not see the screw

How to diagnose this problem? Yes, it’s very simple: you need to restart the computer while holding down the special keys to enter the BIOS. Depending on your computer model, this may be either the “Del” key or the “F2” key. Although there may be other options: the PC signals them at startup, just look at what it displays on the screen when the system boots.

Once in the BIOS, you need to go to the “Integrated Peripherals” section and pay attention to the option called “Onboard IDE Controller”. If this option is set to “Disabled”, this means that for one reason or another the BSVV does not see your screw. Here is an explanatory picture:

Try this:

Carefully check all contacts and connectors, following the instructions for your motherboard and hard drive.
Remove the system clock battery from the connector and keep it disconnected for 10–15 minutes, after which you can insert it again.
Set the “Onboard IDE Controller” option to the correct position, i.e. to “Enabled”.

If these manipulations fail to revive the screw, contact a specialist.

The BIOS sees the screw, but the OS does not see it

So, let’s look at the situation when the BIOS sees it, but Windows doesn’t. Also a fairly common story. The ability to log into the OS recorded on any of the partitions may be influenced by the boot order set in the same BIOS.

If the first in line are faulty or unresponsive devices that are physically present in the system, then the boot process may freeze.

In this case, you need to go to the BSVV settings and change the loading priorities in a direction convenient for the user.

For example, remove from the highest priority devices a flash drive, from which it is basically impossible to boot if it does not contain an image of a certain OS or contains its “broken” image. Here's what the priority window looks like in practice:

Place the screw first on this list.
