Collection of factory settings the BIOS does not see hard. Hard drive not detected in BIOS

The wonderful times, when no hard drives simply existed, have long since sunk into oblivion. The development of high technologies differs from others in that it does not obey general laws, but tears forward like a stratospheric rocket.

Tape drives may have failed more often than modern magnetic disks, but the reasons for their failure were much more understandable. Although ... what are we talking about! No, we are not encouraging everyone to return to the Stone Age. God forbid! We just give some comparisons, which, according to certain parameters, do not always turn out to be in favor of modern technology.

So, you have a broken hard drive or you suspect that the failure lies in it - in the inadequate operation of this complex and obscure device. You are saved if there is another PC near you that sees its own hard drive. Just swap the two discs and make sure that someone else's machine recognizes it as working.

If so, then the problem lies in the wrong settings on your system. If the second computer does not see your ill-fated screw, it means that it is really faulty, and at least it needs to be brought in for repair. As a maximum, just throw it away and replace it with a new one, if some critical data was not contained on its surface.

We will assume that the screw was detected by another computer and the essence of the problem should be found in the settings. It so happens that the BIOS (Basic Input-Output System) does not recognize this or that hardware. In this case, Windows itself usually does not recognize it. Let's trace this on the example of a hard drive.

BIOS does not see the screw

How can this problem be diagnosed? 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 can 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 at the time 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", then this means that for one reason or another BSVV your propeller does not see. Here is an explanatory picture:

Try this:

Carefully check all contacts and connectors, in accordance with 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, that is, to "Enabled".

If these manipulations do not work to revive the screw, contact a specialist.

BIOS sees the screw, but the OS does not see

So, let's analyze the situation when the BIOS sees, but Windows does not. Also a pretty common story. The ability to enter the OS, recorded on any of the partitions, can be influenced by the banal order of loading, put down in the same BIOS.

If the first in turn are faulty or unwilling to respond devices that are physically present in the system, then the boot process may hang.

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

For example, remove a USB flash drive from the highest priority devices, from which, in principle, it is impossible to boot, if it does not contain an image of a certain OS or contains its "broken" image. This is how the priority window looks in practice:

Place the screw at the top of this list.

Check for serviceability

The drive can become unusable due to the following damage:

after hitting or dropping a laptop
mechanism wear

Any device or component will eventually exhaust its resource and break down. To check if it works, connect it to another PC. If it doesn't work, you need to buy a new one.

Always remember that when using your laptop, it must not be placed on an uneven or soft surface. The ventilation slots must be open so that air can flow freely into the cooling system.

Correct connection

The next thing to do if the computer does not see the hard drive is to check if the connection is correct. Make sure that:

Motherboard

In some cases, this problem is associated with a malfunction in the motherboard. There is a possibility that the south or north is out of order, the contacts designed to connect to the hard drive are burned out. What to do? In such a situation, to normalize the operation of the computer, it will need to be partially repaired or completely replaced.

Jumpers

If you own an old computer with an IDE hard drive, then pay attention to the jumpers. There is an additional connector on the case for setting the HDD priority. One of the four pairs of contacts located in it is fixed with a special jumper.

Check the presence and correct location. If you want the connected device to be the main one, set it to the “ Master". If you are connecting a second drive, you should set it to " Slave».

Also, be sure to check their condition in other similar devices. Most often, it is these tiny details that provoke malfunctions in the system, due to which, in turn, Bios does not recognize the components.

Additional loop

Do not use a single data daisy chain to connect multiple devices, even with additional connectors. It is best to connect each drive separately. Perhaps your hard drive in BIOS is precisely for this reason.

Lack of food

This problem often occurs after a complete computer upgrade or replacement of a component, and if you have a weak power supply installed, it may simply not "pull" all the devices installed on the PC.

BIOS settings

In the new generation of laptops and netbooks with SATA interface in the BIOS, hard is recognized as “ Drive»Device, but sometimes it may have a different name.

It is also necessary to find the partition that is responsible for hard drives, usually it has in its name "IDE Controller" or "SATA Controller". Make sure your drive is set to “ Enabled" or " ON».

2. Also select in the “ First Boot Device»Your storage device.

Physical failure or factory defect

With various damages, the performance of conventional magnetic disks (HDD) is quickly disrupted, and how correctly it ceases to be recognized. This is usually caused by being shaken, dropped or hit. In this case, the internal mechanics partially breaks down (magnetic heads stick, motor bearing wedges or magnetic plates themselves are damaged). In this case, it is subject to professional repair only. HDD, it does not show any signs of life, most likely you have gotten a marriage. The best solution is to take it back to the store while the warranty is in effect. Since in case of self-repair, it may not be accepted back from you.

If you could not solve the problem yourself with the help of our advice, we recommend that you contact qualified specialists for quick troubleshooting.

Each of us, users, has our own ideas about how much disk space is sufficient. Nevertheless, a certain amount of time passes, and we are forced to increase the storage areas of memory. It is at such moments that a rather difficult situation for many of us can arise - the BIOS does not see the hard drive that we connected. However, the problem of "electronic blindness" can arise in other circumstances ...

How to check if a device is enabled in BIOS

Enter the BIOS system settings menu. Depending on the version of the basic microsystem, the section of interest to us may be located in one of the tabs listed below.

Award and Phoenix - "Integrated Peripherals" - "OnChip SATA Controller" - "Enabled".

AMI BIOS - "Advanced" - "Onboard Device Configuration" - "Enabled".

Please note that the "Enabled" parameter must be present everywhere.

Is the hard drive detected in the BIOS?

Some modifications of hard drives will not work in tandem with other drives if the jumpers are incorrectly set, which determine the priority for use in the BIOS. Install them according to the scheme indicated on the hard drive itself, in the "Master" or "Slave" position acceptable to you.

You can make sure that the connection is correct on the "Standart CMOS Setup" tab, if you have an "AMI BIOS", or in the main window of the "Award and Phoenix" interface, the "Main" tab, respectively.

The bottom line: why the BIOS does not see the hard drive

Minor oversights in the hardware upgrade process can ultimately lead to wasted time. Therefore, first of all, you need to make sure that the hard drive is connected correctly, and the connecting cable firmly takes its place in the corresponding connector.

It should be noted that during operation, under the influence of vibration, some of the contacts of the DATA cable may simply be disconnected. Mechanical damage is not excluded, as a result of a critical bend of one of the wires, the contact will also be broken. As you understand, in such cases it is necessary to replace the loop interface.

How to check if the hard drive is working properly?

First of all, you need to find out whether the power is being supplied to the drive controller and whether it is coming in sufficient volume. For the sake of simplicity, resort to the solution below.

Remove the protective cover of the system unit.

Turn on your PC.

Touch the hard drive, if you feel vibration from the rotation of the spindle - it means the disk is spinning, which means that the power comes to it.

Otherwise, turn off the computer and disconnect the interface cable.

Turn on the PC again and tactilely check if the disc rotates inside the protective casing of the hard drive. If not, the drive is faulty.

In any case, for example, to be on the safe side and be more convinced that your assumptions are correct, try connecting the "problem" drive to another computer. You may need to take advice from ... Alternatively, try to restore the hard drive to work using specialized programs, for example, "Victoria".

Summing up

The problem we touched upon "BIOS does not see the hard drive" is quite common among laptop owners. You can fix this kind of problem by installing a special driver, to a certain extent the Intel Rapid Storage Technology (Intel RST) driver. We will assume that you have managed to solve the problem of the "invisibility" of the hard disk, and therefore all the best to you!

Hello, we have come to you with a problem. We decided to upgrade the computer, but not the whole one, but the main components: the motherboard, RAM, video card and power supply, all this was safely installed in our old case. And now the problem is, our BIOS is not in there is a hard disk and a floppy drive, both IDE interface devices remained from the previous computer and we did not change them, the master in the service center connected both these drives to our new motherboard with one IDE cable, since there is only one IDE controller connector on the motherboard. We brought the system unit home and when you turn on the computer only a black screen, go to the BIOS, there is an inscription: Primary IDE Master No detected and Primary IDE Slave No detected. Would have gone back to the service, but we do not live in the city. What can you think of?

BIOS does not see the hard drive

I come across a similar situation quite often, for sure before your hard drive and floppy drive were connected to the old motherboard, using separate loops, to two different IDE connectors, and both worked in the Master position, that is. In the service, you simply connected two of your devices to one loop, but they forgot about the jumpers, now both of your devices are working in Master mode, because of this, the conflict and as a result BIOS does not see the hard drive and the floppy drive too.

In our article we will work with a hard drive and an IDE interface drive, if you have little experience, how to connect and disconnect and what errors you may have, read in more detail If this article does not help you, try another one, in it described.

Where did you assemble your computer? We hurried a little and now we will try to fix everything. The IDE interface devices need to be configured with a jumper, which will tell your computer how to properly access the drives (and the floppy drive). When working with IDE devices, it is very important for a computer to know who is the master device of the Mas ter on the same loop, and who is the slave of the Slave, this is decided by the little one. The contacts on which the jumper is placed are located directly on the drive. The instructions for the location of the jumper are usually located on the drive case. We turn on the computer and go to, first of all, you need to make sure that the IDE controller is enabled in the Integrated Peripherals tab.

Make sure the power cables are connected.

In our article, we will configure the jumpers first of all with the Seagate hard drive, then, to gain experience with the Western Digital and Maxtor hard drives, Sony NEC Optiarc will act as the drive. Pay attention to the screenshot. I have a similar problem too, BIOS is not in there is a hard disk and drive, both devices are not detected Primary IDE Master No detected and Primary IDE Slave No detected.

From the very beginning, we look at how the jumper is installed on the Sony NEC Optiarc drive. According to the instructions located on the drive case, the extreme right position is Master, which means that the drive is already connected with a jumper as the main one. It is best to connect the Master to the end of the loop.

Now let's move on to the hard drive, the Seagate hard drive is also connected as a Master, two main devices on one loop is an inevitable conflict.

The result for both devices in BIOS is No detected. Let's avoid device conflicts and leave our drive as Master, and connect the Seagate hard drive as Slave. We look at the instructions and see that the Seagate hard drive works in slave mode without a jumper at all, remove the jumper completely.

We see if everything is connected correctly and turn on the computer. The result is obvious, both devices were found and identified. Now we also connect the Western Digital hard drive, everything is perfectly defined in the BIOS. Behind it is the Maxtor hard drive, everything is fine too.

Many may notice, and if the hard drive is connected to the end of the loop and made the Master-Master, and the drive in the middle and the slave-Slave, because the more important device is always connected to the connector at the end of the loop, if you want to do so, the work of the hard drive is still our priority. Then the main thing is not to bend the train itself too much, do not be too smart, it will look like you on the screenshot.

We take our first Seagate hard drive and put the jumper in the extreme left position Master, and connect it to the connector at the end of the IDE cable.

and the jumper on the Sony Optiarc drive to the Slave position, that is, according to the instructions in the middle, and connect it to the ribbon cable connector also in the middle.

The BIOS does not detect the presence of an internal hard drive - a situation, unfortunately, not uncommon. Let's consider the main causes of the malfunction, as well as ways to eliminate the problem.

Some manufacturers disable unused ports in BIOS by default. To check their current status, you need to enter the BIOS.

Outdated drivers prevent the hard drive from starting and reading data from it. There are three ways to update drivers:

contacting the manufacturer for help;
download from the manufacturer's website;
manually.

For this:

If Windows says it cannot find a new driver for the disc, download the latest version from the device manufacturer's website.

If the above steps don't work, try reinstalling the drivers:

Windows 2000 and XP require additional drivers to be downloaded from the motherboard manufacturer.

The listed items only work for PC systems.

Broken or disconnected data cable

Always check the connections of the motherboard and HDD for pin integrity. A bent, pinched, squashed cable can damage hidden wiring. These cables must be replaced.

Using connectors:

blue - to connect the motherboard;
gray - for connecting with connected devices;
black - for connection with masters.

Disc does not spin

The problem occurs when the drive is not receiving enough power to operate. This can be verified by the following steps:

A hard drive may not spin for various reasons, but one of the most common is physical damage. If the hard drive has recently been formatted, or if it has been damaged by water, this could be the source of the problem.

Incorrect disk connection settings

It is recommended that all Seagate ATA hard drives that are compatible with the Cable Select jumper option are configured as Cable Select. On computers manufactured prior to October 1998 and not supporting UDMA 66 or higher, the Master / Slave jumper must be used.

In an ATA disk, all devices powered by a UDMA cable should likewise use the cable selection setting.

Incorrect BIOS setup in Windows

If the user recently made changes to the BIOS, the settings they entered may not be compatible with the HDD. UEFI / Legacy BOOT mode is the most difficult in this regard, so users should take extra care when making BIOS changes.

Also, the SATA controller may have the wrong operating mode selected in the BIOS. For most PCs, there are three main modes of operation for a SATA controller:

If the hard drive does not support one of these modes, or if Windows was installed and booted in one mode but configured in a different mode, the boot process will stop.

Bad hard drive

Hard drives are mechanical devices and, like all mechanical devices, they can fail unexpectedly. Main reasons:

Firmware or manufacturer errors (factory defect)

All reputable hard drive manufacturers test their products thoroughly before selling them to consumers. But even with modern testing methods, defective hard drives still occasionally hit the market. Most manufacturing defects appear within the first year of use, so it is recommended that you never trust a brand new hard drive with critical data and keep backups up to date somewhere else.

Overheat

Most hard drives are designed to operate in temperatures between 5 and 50 degrees Celsius, and some newer hard drives can operate up to 60 degrees Celsius. Although overheating usually does not lead to a fatal crash, it often results in data corruption and read errors. It is important that the computer or laptop is well ventilated, especially during the summer months. Use thermal grease between the heatsinks of the processor fan.

Electronic malfunction

Each hard drive contains many sensitive electronic components. A sudden power failure, preceded by a brief power surge, can cause these components to malfunction, rendering the entire hard drive useless. High quality surge protection is by far the best way to protect against electronic hard disk failure.

File corruption

Unethical PC shutdowns, accidental closing of running applications, the use of malicious or questionable software, power surges are factors that contribute to the corruption of system files. The solution is to always use the standard way to shut down the PC by exiting running programs before shutting down the system.

Mechanical failure

Cause. A hard drive contains moving parts that can deteriorate over time and ultimately lead to mechanical damage to the hard drive. A virus attack can erase hard drive data, alter hard drive behavior, or damage system files, etc., ultimately resulting in a mechanical failure. For example, rootkit viruses become active at system startup and disrupt the system at the BIOS level. Although operating systems starting from Windows 8 / Windows 8.1 have the ability to detect this malware and remove it using UEFI (Unified Extensible Firmware Interface) technology.

Advice! Common measures that can increase the lifespan of a hard drive are regular or weekly system updates, running the latest anti-virus program, replacing the hard drive after 3-4 years of use, etc.

To access data from an external hard drive that Windows has detected but cannot open normally, follow the steps below:

Download and install EaseUS - hard drive recovery software.

Now it's time to open your external hard drive on Windows 10, 8, or 7.

Accessing BIOS in Windows 10

Recent versions of Windows are characterized by significant processing speed, and therefore pressing a key at startup does not always work. To access the BIOS if the hard drive is not detected, it is recommended to follow these steps:

Start by going to settings. Click on the Start Menu icon.
Then you need to select update and security.
Go to "Recovery" from the menu on the left.
Then you have to click on the "Restart" button in advanced startup. This will reboot the computer into a special menu.
Select troubleshoot.
Go to advanced options.
Select UEFI Firmware Settings and finally click on reboot.

After rebooting the system, you will be taken to UEFI, one of the BIOS pages.

Output

The case where the hard drive is not detected is a hardware problem and requires knowledge. BIOS availability can seem daunting when using Windows 10, and for that reason, this article provides steps to help you get to the BIOS.
