Hard disk drives are currently at the forefront of the long-term storage industry as devices that have large capacity, low cost, and high reliability and speed characteristics. Although technology in the field solid state drives have not progressed as fast as other areas in the field of computer hardware (processor, memory, etc.), however, hard drives are significantly superior to their predecessors in capacity and speed.
Over the past ten years, great results have been obtained in the field of upgrading HDD parameters, which have been developed due to the transition to another technology for transferring data between hard drive and motherboard - serial interface Serial ATA (SATA). Today, SATA hard drives have almost ousted IDE hard drives from sales due to speed. In addition, connect SATA drives to motherboard many times lighter and faster than IDE hard drives.
Users hard drives in the SATA interface often encounter a problem when HDD not recognized by Windows. How to fix the situation when Windows 10 does not see second hard the disk 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, it is impossible to load the operating system.
For the most part, the reasons why the BIOS does not see the hard drive can be divided into three groups:
- Defect hard drive
- Poor SATA connection to motherboard/hard drive or bad SATA cable
Consider all situations when the BIOS does not see the hard drive.
Hard disk defect
In general, it is not easy to harm a hard drive by accident. When a computer or laptop does not see the HDD, the first thing to do is to see if there is any external damage on it. First you need to check the jumpers, because their malfunction is the most common reason why the BIOS does not see the hard drive. The jumpers are located on the back side of the hard drive. What defects can be seen with your own eyes: the jumper is bent, partially broken or completely fallen off, oxidized.
In this case, if the hard drive on the computer has just been bought, then it must be returned to the store to be replaced with another one. If the carrier has been in operation for a long time, then you will have to buy a new one yourself.
If the contacts of the SATA connector are oxidized, then in this case it is necessary to treat the jumpers with a solution that eliminates rust (lemon, soda, acetic). You can read more in this article.
In some cases, surface inspection reveals physical defects. These defects include:
- Chip defects on an open hard disk board;
- Damage to the HDD case;
- Destruction of parts of the hard drive (note: the motor is broken).
In the presence of the above problems, it is necessary to assess the completeness of all damage. You can evaluate it from yourself or from those who understand more. If the hard drive can be repaired, then it makes sense to give it to 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 on it. You can determine whether there is power on the hard drive by such a sign as rotation. Since the disk itself is in the case, you cannot 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. In the presence of 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 if the computer sees the HDD.
Problems with the SATA cable
To check the SATA cables, you need to open the system unit and look at the cables connected to the system board and hard drive. If there are visible defects, then it is worth replacing the SATA cable. SATA cables can be bent, broken, and the hard drive is not visible to the computer. If there is no visible damage in the data cable, then you need to check how tightly the SATA cable is connected to the hard drive connectors and the motherboard.
Misconfigured BIOS options
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
For diagnostics, when you turn on the computer, you need to go to the BIOS menu. To get into the BIOS settings, you must press the F2 or Del keys at the very beginning of the computer boot, depending on the manufacturer of the motherboard. As a rule, keyboard shortcuts are specified at system startup. When entering the BIOS, we check if 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. We press Enter and we see that opposite this section there are two inscriptions Enabled (enabled) and Disabled (disabled). We check that it is Enabled. Then save the configuration and reboot.
If this action If that doesn't work, 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 motherboard. We take it out and wait for 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 it differs from others in that it does not obey general laws, but rushes forward like a stratospheric rocket.
Tape drives may have failed more often than modern ones. magnetic disks, but the reasons for their breakdowns were much more understandable. Although ... what are we talking about! No, we do not call everyone to return to the Stone Age. God forbid! We simply give 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 breakdown lies precisely 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 these two disks and make sure that someone else's machine recognizes it as a working one.
If so, then the problem lies in the wrong settings on your system. If the second computer does not see your ill-fated screw, then it is really faulty, and at least it needs to be repaired. As a maximum, just 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 must be sought in the settings. It happens that the BIOS (Basic input-output system) does not recognize this or that hardware. In this case, it is usually not recognized by Windows itself. Let's follow this on 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 the computer model, this can be either the "Del" key or the "F2" key. Although there may be other options: the PC signals about them at the start, 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, the BSVV does not see your screw. 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, 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, we analyze the situation when the BIOS sees, but Windows does not. It's also a pretty common story. The ability to enter an OS recorded on any of the partitions can be affected by the trite boot order set in the same BIOS.
If the first in turn are faulty or unresponsive 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 download priorities in a direction convenient for the user.
For example, remove a 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. Here's what the priority window looks like in practice:
Put the screw in the first place in this list.
Other HDD problems
Sometimes the visibility of the device by the operating system is periodic: it is either available or not. The reason for this phenomenon may be a weak computer power supply - replace the unit, and everything will return to normal.
Alternatively, you can disconnect some gluttonous device from the power - this will lead to the same effect. If two disks of the same brand are installed on the same machine, this can also lead to conflicts. Such disks need to be connected and configured in turn.
There is another trick to fixing the situation when the BIOS sees the hard drive, but the Windows OS does not. Open the "Disk Management" snap-in from the "Start" menu => "Control Panel" => "Administrative Tools" and try to "play" with parameters like volume and partition labels. Here is an explanatory drawing for this alternative:
Well, if none of the above helped, you will have to contact the masters computer repair. It's not that expensive these days.
When you turn on your computer, the BIOS checks the hardware for functionality. Accordingly, if the hard drive is not visible in the BIOS, then the system will not start, since Windows files will not be detected and read. Visually, this error is accompanied by a black screen with a notification that the hard drive was not found.
Possible reasons
If the BIOS does not see the hard drive, then the cause of this phenomenon can be both hardware and software errors in computer operation. Consider the main negative factors:
- Winchester is disabled in BIOS.
- The hard drive is incorrectly connected or damaged.
- Jumpers set incorrectly
The described reasons are more related to the HDD, but if you have an SSD drive, then some tips apply equally to it.
Incorrect hard drive connection
If the BIOS does not see the hard drive, then the problem may lie in the incorrect connection of the hard drive to the motherboard. Check that all loops are in good condition, the cables do not have kinks and cuts, suitable ports are used for connection. If a physical property flaw is found (such as a broken cable), it should be repaired, and then try to boot the system again.
The recommended length of the SATA cable is 1 meter. If your cable exceeds this value, then it must be replaced with a shorter one, as this is the reason for incorrect BIOS operation. Be sure to check that all cables are securely connected - sometimes they just fall out of the connectors.
Jumpers problem
If you have two hard drives connected at the same time, and at the same time you are using the IDE interface, then you need to check that the jumpers on the hard drive are set correctly. The jumpers tell which HDD is the master (i.e. Master), and which is the slave (Slave).
Note: If you have two SSD drives connected, then no jumpers are required.
Instructions for correct installation jumpers can be found directly on the hard drive case. If there are two disks, then one should be set as " Master", And the second as " Slave". Be careful: some hard drive models work in slave mode without a jumper.
Pay attention to other equipment - if it is connected incorrectly, the BIOS will malfunction, which leads to an error when trying to detect the hard drive. The cause of the problem can also be ordinary overheating: check the cooler and put the entire cooling system in order.
BIOS check
Any hardware connected to the computer is turned on and off through the BIOS. Sometimes software failure leads to the fact that a change in the operating mode of the device occurs without the knowledge and participation of the user.
- To start .
- Make sure the SATA connector is set to Auto, that is, it is detected automatically.
- Find the "SATA Configuration" option and set it to "Enabled".
If you are afraid to climb the BIOS settings, just try resetting them to the factory state. Remove a small battery from the motherboard or use the Load Optimal Defaults item in the Exit section.
Winchester damaged
If no manipulations with the cables, the hard drive itself and the BIOS bring a positive solution to the problem, then you should think about the state of the hard drive. First, try connecting it to another computer. If the BIOS does not see the hard drive here, then the media is most likely broken. In this case, it is better to think about how to save the information, since the damaged hard drives themselves are usually not recoverable.
Why the BIOS does not see the hard drive is a question that is heard more often than others in various IT forums. The hard drive may not be recognized by the BIOS for several reasons. In the case of self-assembly of the computer, it is possible that the interface cable that runs from the connector on the motherboard to the hard drive itself was incorrectly or poorly connected. The problem can arise if the power connector does not provide proper contact and the device remains trite without electricity.
There are currently two main interfaces connection of rigid disks to the computer - IDE and SATA. Despite the fact that the first interface is already considered obsolete, it can still be found on a fairly large number of PCs.
Information in the case of using the IDE interface is transmitted over a multi-core flat cable of two types. The first type is low speed, contains 40 conductors, and is best suited for connecting CD drives. The second type is used for data transmission according to the UDMA66 standard and higher; it differs from the first type in the presence of additional shielding conductors interspersed with signal ones; This cable consists of 80 thin strands and is great for high-speed hard drives. When connecting these cables to the connectors on the motherboard and hard drive, you should pay attention to the design of the connector, which, thanks to the efforts of its developers, eliminates the situation with an erroneous orientation of the connector in space and incorrect connection of the corresponding pins. The so-called "key" in the form of a protrusion on the "mother" connector (with holes) must fall into a special recess in the mating part of the "father" connector (with pins). If there is no "key" on the connector, then wrong connection can be recognized by the permanently lit "HDD" LED on the system unit And that means you have to flip the connector.
If the hard disk after correct connection still not detected by the BIOS, then:
- It is necessary to check the interface cable itself - it is possible that it has become unusable and should be replaced;
- When using IDE –> SATA adapters, the problem may lie in them, therefore, the only way to eliminate this possibility is to replace the adapter with a known good one;
- Check in the BIOS whether the IDE controller itself is enabled;
- You can reset the BIOS settings to factory defaults or factory presets.
The hard drive will not be detected by the computer even if the jumpers on the hard drive itself are incorrectly set. To do this, you need to check the sticker on the hard drive and set it in accordance with the connection configuration of your equipment.
In case of use SATA interface It is unlikely that any problems will occur, but if they do, the solutions provided for the IDE interface should be used, with a few exceptions.
If you need more complete instructions, on the issue of visibility of the hard drive through the BIOS, unsubscribe in the comments, we will record a separate video for you in which we will tell you why the BIOS does not see the hard drive and describe general recommendations for troubleshooting this problem.
Good day to all, dear readers! In this article I will try to explain why the BIOS does not see the hard drive - and I will also tell you how to solve such a problem in my article.
This problem, when the hard drive is not detected by the computer, is the most common. It occurs on both old and new computers. It also happens with new and old, external and built-in HDDs.
First, of course, you need to find out the cause of such a problem. Sometimes users can decide everything on their own and get it working with Windows and a laptop hard drive.
Why does the computer not see the hard drive?
I note right away that there are several reasons due to which the hard drive refuses to perform its functions. Such reasons include:
- For the first time, a new sata or ide disk was connected;
- There were problems with the cable or wires;
- Perhaps the BIOS is incorrectly configured or completely out of order;
- Weak power supply;
- Low cooling system;
- The hard drive itself is out of order.
Yes, you need to diagnose, and only then solve the problem. Let's say an inexperienced user will probably have some difficulties with this. Let me help you, and together we will figure out what and how.
The first connection of the hard drive
If this is your first time connecting a screw, then most likely the system simply did not see it. Yes, it is physically in working order, but it is not displayed among local drives.
In order to fix this problem you need to click on Win keyboard and R, write compmgmt.msc and indicate "Ok".
Find and select Disk Management.
In the window that appears in the middle, all your connected drives will be identified, including your problem hard drive. As a rule, it is such because of the wrong assigned letter.
Find the required disk and click on it right click mouse, and then select "Change Drive Letter or Drive Path...".
A window will open in which you will have to click on the "Change" button.
Now select the desired letter and select "OK".
Wrong format
For the normal functioning of the disk in Windows, the NTFS format is required.
Just like in the instructions above, go to "Disk Management", that is, repeat the previous first two steps. After that, right-click on the disk and select "Format".
Select file system– NTFS, and click OK.
BIOS does not see the hard drive - setting
In some cases, the wrong device priority for booting may be set in the BIOS. When booting the PC, press F2 (or Del). Which key to press will be indicated when the PC starts. By pressing the desired key, you will enter the BIOS.
Please note that due to differences in BIOS versions, the names of menu items hereinafter may differ slightly.
Look for the "Boot" tab. Use arrows to control. Set your HDD to the first place in the list of boot devices (1st Boot Priority/First Boot Device).
Press F10 to save and exit and then press Y to confirm. After that, the PC will boot from the device you set up.
SATA mode of operation
Often, users in the BIOS do not have an operating mode that is compatible with the IDE. In order to make a change, you need to go into BIOS, select Main, Advanced or Integrated Peripherals and find the SATA Operation, Configure SATA As, or OnChip SATA Type setting.
Select IDE or Native IDE, press F10 and type Y.
BIOS does not display hard drive
If the BIOS cannot determine your hard drive, then most likely it is a matter of incorrect settings or their failures.
Incorrect settings appear due to user actions, and failure can occur for various reasons. So, starting from power outages and ending even with infection of the system. This can be indicated by the system date - if it is not accurate, then you have undoubtedly experienced a failure. To fix this problem, you need to reset all settings.
Look for the Clear CMOS jumper on the motherboard.
Change the jumper from pins 1-2 to 2-3, hold them for 20-30 seconds and then return to initial position. Besides, there is another way. Find the motherboard in the system unit and remove the battery from it.
You will need to return it back in 25-30 minutes.
Conclusion
Now you know what to do if the BIOS does not see the hard drive. I hope you were able to solve your problem, thank you all for your attention, and don't forget to ask any questions in the comments!
