How to Fix ATA/SATA Hard Drive Not Detected in BIOS?

Summary: A hard drive also known as a hard disk, is a non-volatile data storage device. It is electromechanical with a motor and a platter run by a controller circuit. Data can be stored in a hard drive even when the device is switched off (unlike RAM). Older ATA and more modern SATA drives are highly efficient. But a lingering problem is hard drive not detected in BIOS. We show step-by-step solutions.

What is BIOS and How Does It Start Your Computer?

BIOS or Basic Input/Output System is a computer program stored on an EEPROM chip found in the motherboard and powered by a tiny battery. When you press the power button of an inactive desktop or laptop, the BIOS turns on and initiates the hard drive and CPU from a dead state. The OS jumps to life and pulls the system files from the hard drive into RAM and starts the computer. The process is known as booting.

How Does UEFI Modernize the BIOS Experience?

Modern BIOS systems are now known as UEFI (Unified Extensible Firmware Interface), a Microsoft standard. UEFI offers more advanced features compared to traditional BIOS, including support for larger hard drives and faster boot times. While UEFI performs similar functions as BIOS, it enhances the overall boot process and system management.

What is the ATA/SATA Hard Drive Not Detected in BIOS Issue?

When your ATA/SATA hard drive is not detected in BIOS, it means that the BIOS is unable to recognize or communicate with the drive. This issue can be caused by loose or disconnected cables, incorrect BIOS settings, or a malfunctioning hard drive.

Causes of ATA/SATA Hard Drive Not Detected in BIOS

Some of the reasons for ATA/SATA hard drive not being detected in BIOS are:

1. Loose or Disconnected Cables: If the cables connecting the hard drive to the motherboard are loose or disconnected, the BIOS may not detect the drive. Ensure all cables are securely connected.
2. Incorrect BIOS Settings: Sometimes, the BIOS settings may not be configured correctly to recognize the hard drive. Check and adjust the BIOS settings, such as enabling the SATA controller or setting the correct drive mode.
3. Faulty Hard Drive: A malfunctioning or failed hard drive may not be detected by the BIOS. Testing the drive in another system or using diagnostic tools can help determine if the drive is the issue.
4. Power Supply Issues: Insufficient power supply to the hard drive can prevent it from being detected. Ensure that the power cables are connected and functioning properly.
5. Outdated BIOS: An outdated BIOS version may not support newer hardware or configurations. Updating the BIOS to the latest version may resolve detection issues.

If your hard drive has any of the above problems except the last, you can adopt the following measures to troubleshoot and resolve them.

How Will You Fix a Hard Drive Not Detected in BIOS Error?

First of all, the diagnosis of the problem is essential. 

1. Check for Faulty or Unplugged Power Supply

A hard drive has two cables, one for power and one that connects it to the motherboard.

Power supply failure or SMPS failure is very common, especially in devices that are used for gaming (besides work). SMPS fails due to age and overload. It causes ATA/SATA hard drives not to be detected in BIOS.

Step 1: Use another power supply unit. A normal PC requires a 300-watt power supply and a gaming PC about 500 watts.

Step 2: If step 1 is not enough, use a new data cable to connect the hard drive to the motherboard.

Step 3: If steps 1 and 2 do not work, use a different ATA or SATA port. Older motherboards (pre-2006) have at least 2 ATA ports and motherboards made from 2006 have at least 4 SATA ports.

Note – What we call ATA (old standard) is actually PATA or Parallel ATA.

2. Open BIOS and Enable Device

• Enter BIOS by pressing F2 Key, F10 Key, F12 Key, and Delete Key(depending on the motherboard manufacturer) at boot.
• Enable CSM ATA and SATA devices in launch CSM.
• If you do not know how or if the Asus motherboard is so old that advice is not available from the manufacturer, go to the last available option of BIOS (usually on the rightmost side) and select “Load Optimal Defaults”, save and exit.

• BIOS might have become corrupted. In case the BIOS is a very old version (pre-2010) the hard disk might have to be attached to an ATA to SATA converter cable and the data copied to the advance mode of the latest version drive.

• If your PC is legacy hardware (pre-2006) and has an ATA hard drive it would be difficult to find an SMPS that matches it. The only recourse is to use an ATA to SATA converter cable to withdraw the data to a newer drive.
• Reboot the PC after removing all DVD and CD drives and USB storage media. This should solve the ATA/SATA hard drive not detected in the BIOS problem.

Note: “Load Optimal Defaults” should load the perfect conditions for an OS which means all hard drives are auto-enabled in future sessions.

3. Fix Improper Installation of ATA/SATA Drivers

There are Three Ways in which you can Update Drivers:

• Contact the manufacturer for updates on the driver.
• Download the updated driver from the manufacturer’s website.
• Follow the below-mentioned manual process to update drivers.

For Windows:

• Go to the default setting and then go to  Control Panel .
• Select  Device Manager .
• Choose and click on the hard drive to expand categories.
• Right-click on the name of the hard drive and choose  Update Driver .

If the above method fails, re-install drivers with the help of the following measures:

• • Open  Device Manager .
  • Right-click on the hard drive and  Uninstall .
  • After that, restart the PC and Windows will automatically reinstall the drivers.

For MAC:

• Click on the  Apple  in the upper left corner of the screen
• Select  Software Update .
• Update and reboot.

4. Faulty/Damaged Hard Drive

In most cases, you would be able to resolve minor ATA/SATA hard drive detection problems with the help of the methods mentioned above.

If you can’t locate why the error ATA/SATA hard drive not detected in BIOS is happening, there are chances of physical fault/damage in the hard drive.

Maybe the PCB is burned out and the hard drive actually appears as “dead” to the BIOS. This would lead to ATA/SATA hard drive not detected in BIOS error.

In such cases, you must immediately seek assistance from data recovery professionals. Fiddling with the drive on your own can cause permanent physical damage and loss of data.

Data Recovery Service – Hard Drive Not Detected in BIOS

When your hard drive isn’t detected in BIOS, it can be a serious issue, but professional data recovery services can help. Experts in the field have developed specialized solutions to recover data from damaged hard drives, including cases where BIOS isn’t recognizing the drive.

It’s crucial to have your hard drive examined in a controlled environment, such as a Class 100 Clean Lab, to ensure the best chance of successful data recovery. Look for a professional data recovery service provider with extensive experience—ideally, over 30 years—in the industry. Choose a provider with branches or locations near you to facilitate convenient service and support.

FAQs

1. Is it normal for a hard drive to not show in BIOS?

It is very normal. A hard drive is susceptible to failure, much more so than many other components. The BIOS cannot recognize a “dead” hard drive or one to which no power is supplied leading to ATA/SATA hard drive not detected in BIOS error.

2. What is ATA and SATA?

ATA and SATA are interfaces between the computer and the hard drive. SATA is almost exclusively used since 2006. Rare legacy machines run serial ATA. What we know as ATA is actually PATA or Parallel ATA.

3. Can you transfer data from PATA to a SATA drive?

Certainly, we can. Technicians use connectors known as ATA to SATA cables and transfer data to a new hard drive (or solid-state drive if you wish).

4. Do I have to pay even if no data is recovered?

Not at all. You pay only if the hard drive recovery project is successful. Before you send us the drive we shall have a detailed discussion with you about what is possible in our lab.

5. I have an old PC with a PATA drive. Should I replace it?

Many enthusiasts continue to run older machines. But PATA cannot support the transfer speeds needed for Windows 11 or MacOS 12 Monterrey. Modern computing also needs enormous space that a 40 GB PATA drive cannot offer.  If your drive is working, back it all up to a USB drive or cloud and replace the drive.
