How to Fix Computer Primary Slave Hard Disk Error

Primary Slave Hard Disk Error Pops out on POST

"Hello, in order to expand PC hard drive memory, we do have added a secondary hard drive to my Windows 7 laptop and hope the computer low disk space error would be removed successfully. However, luckily the related no enough space issue is fixed and another primary slave hard disk error also comes out. Honestly, after connecting this hard disk there well, we just start the PC as usual. However, the computer is stuck on boot up screen and says: 'Primary slave hard disk error, press F1 to resume'. And without knowing much about such PC error problems, I just click F1 button and the same error message pops out again. What should we do to resolve such primary slave hard disk error problem? Have we done something wrong to add the secondary disk? Please help me."
Hello, friends there! The related computer primary slave or master hard drive errors often occur to people due to many reasons, like incorrectly master or slave hard drive order setting, loose or incorrect hard drive connection or corrupted hard drive issues, etc. And, under your circumstances, it could be caused by the incorrect hard drive settings. Overall, no matter which one of these reasons behind is more proper for you, go on reading this article to remove such hard drive error issues with ease.

Why People Get Such Primary Slave HDD Error Problems?

There are many causes that could bring people such primary slave HDD error problems. And, here are several major ones for you to analyze your cases:

1). Incorrect master or slave hard drive setting.

Have you set the master and slave drives after you do have added the secondary drive to your PC? Generally, when people do have added the second, third or more hard drives on the same computer, without selecting the master one and slave ones, the PC will often find no boot hard drive during booting up process and could not restart. That’s also why people get such primary slave or master hard disk error issues.
So, also go set the master drive for your computer.

2). Computer master and slave drives are loosely or incorrectly plunged there

Hello, you do have timely set the computer master and slave drives after adding a second or extra hard drive there? However, computer still gives such primary master hard drive error issues? OK! Are you sure you do have plunged these hard drives correctly on your PC. Since the such PC primary slave drive error problems are also able to be aroused by loosely connected or undetected hard drives, you can go unplug these hard drives all and reconnect them all correctly to have another try.

3). Computer hard drives are corrupted somehow

And, generally, the related primary slave hard drive error issues are also able to be aroused by hard drive issues, like corrupted hard drive issues, broken hard drive drives or hard drive bad sector issues, etc. Have you checked these attached hard drives completely with CHKDSK or the like diagnostic tools recently? Are they all are still healthy? If you do have no performing any testing there, it is also not late to check their state now.
Overall, these PC primary slave or master hard drive error problems could often be caused by the above reasons and of course, there are also other possible reasons existing. However, no matter why yours is or are, hope you will not randomly rewrite or format hard drives or do the like improper operations to make everything worse.

How to Fix Primary Slave Hard Drive Error Issues on Windows PC?

Still do not know why such PC primary slave hard drive error comes to you? No worry! Even when you do not know the exact causes behind, you can also follow the below steps to fix such hard drive error problems on your Windows PC. Just act carefully as below:

Step1. Check whether these hard drives are shown well on BIOS interface

In order to make sure whether your added new hard drives are really connected well on your PC, you can go open your computer BIOS and see whether they all are shown well there. If they are displayed well there, you can easily exclude such connection problems and directly skip to the next steps. If not all hard drives connected are listed well there, go close your PC and reconnect them all correctly there.
And here is the simple guide for you to check these hard drives on BIOS interface.
Firstly, turn on your PC and long click Del or F2 to BIOS interface. 
Secondly, click Standard CMOS features from the option list.
Thirdly, check IDE hard drives to see whether your attached ones are displayed well there or not.
Please Note:
*Also try to change other connecting USB cables or connection ports to take chances while trying to reconnect these drives.
*No matter whether your problems are prove to be caused by loosely or incorrectly connection, you are supposed to back up all important hard drive files well and then, rightly and safely turn off computer to disconnect these hard drives one by one.

Step2. Reset the master and salve drive

When all your inserted hard drives have been detected and shown well on BIOS screen, you can also go check whether your PC master and slave drives are set correctly there.
Here is the simple instruction for you to reset the master drive for your computer:
Firstly, also go start PC BIOS interface to open Standard CMOS features option there
Secondly, find Hard Drive option listed there to find the Primary Master section to set the master drive.
Thirdly, press F10 to save these setting and changes.
Fourthly, restart this PC.
Please Note: Pay attention to setting the hard drive with master operating system loaded as the master drive.

Step3. Check or change computer hard drives

And, up to now, when you do have correctly reset your master drive, you do have also got the same problems. Also do not panic! It could be corrupted hard drive issues. Merely go check all attached hard drives and see whether it is necessary to change some completely damaged or failed hard disks. 
In short, these three steps are often suggested to people who have been stuck in such PC primary master or slave hard drive error issues. Hope they will also help you fix everything smoothly.

The BIOS does not detect or recognize the ATA / SATA hard drive

There are six main reasons why a system BIOS will not detect the presence of an internal hard drive.  Here is a list of them.  They are not in any particular order, but you can follow these steps one by one to troubleshoot this problem:

  1. Drive not enabled in the BIOS
  2. Serial ATA drivers are not properly installed
  3. Faulty or unplugged data cable
  4. Drive is not spinning up
  5. Incorrect jumper settings on the drive
  6. Faulty hard drive 


Note: Sections 3, 4,5 and 6 pertain to PC or Mac systems. Sections 1 and 2 pertain only to PC systems.


After verifying that your ATA or SATA port is set to Auto-Detect or is enabled, if you find that your disk drive is not being detected (auto-detected) by the system BIOS, try the following steps to try and isolate/troubleshoot the problem.

  1. Drive not enabled in the BIOS

Most personal computers display a brief message about entering System Setup soon after the power is turned on. System Setup is also called the "system BIOS" or sometimes the "CMOS Setup" - each is a name for the same thing.  

For example, on Dell systems you will see "F2=Setup" in the upper right hand corner during the computer boot-up.  This means to press the F2 key to enter Setup (the BIOS).   Different computer manufactures have different methods to enter Setup, so please check your system documentation for specifics.

If your drive is not detected it may be because it is turned OFF in System Setup. Some motherboard manufactures disable unused ports in the BIOS by default. You will need to enter the the BIOS setup in order to verify their current state. 

When you add a second drive to the system, it may be need to be enabled by turning it ON in System Setup.

  1. The Serial ATA motherboard drivers are not properly loaded.
    When you install older versions of Windows on a drive that will be the boot drive (ie, the C: drive), when it comes time to install Windows, the drive may not be detected.  You might need to update the driver for your computer storage controller.

  Windows 2000 and XP required additional drivers to be loaded.


  Note: These drivers do not come from Seagate; they come from the motherboard manufacturer.


  1. Faulty or Unplugged Data Cable
    • Always inspect the motherboard and hard disk connections for bent or misaligned pins. Folding, crimping, pinching, or creasing data cables can cause the wires to break inside the insulation, leaving the exterior of the cable looking normal. When in doubt of data cable condition, replace it.
    • For SATA cables, Seagate recommends using cables shorter than 39.37 inches (1 meter).  For further information, please see Document ID: 182453.

      Here are some images of Serial ATA cables.  Click to expand.

    • The BIOS will not detect a hard disk if the data cable is damaged or the connection is incorrect.
      Serial ATA cables, in particular, can sometimes fall out of their connection. Be sure to check your SATA cables are tightly connected to the SATA port connection.
    • The easiest way to test a cable is to replace it with another cable.  If the problem persists, then the cable was not the cause of the problem.
    • For ATA drives, Seagate recommends using UDMA cabling with a maximum length of 18 inches. UDMA cables have color coded connections which require proper orientation when connecting.
      See this image:

      • Blue connector - always connects to the motherboard.
      • Grey (middle) connector - is used for slave devices on the cable.
      • Black connector - is used for master device connection.


  1. Drive is not spinning up
    If the drive is not receiving power or receiving an incorrect level of power, it will not spin up. To check to see if this is the cause of the BIOS not detecting the hard drive, follow these steps:
    1. Power off the computer.
    2. Open the computer case and remove the data cable from the hard drive. This will stop any power saving commands from being sent.
    3. Turn on the system. Check to see if the hard drive is spinning. If you touch the side of the drive you should feel a slight vibration. If you do not hear or feel the hard drive spinning, the drive did not start.


  If you cannot determine whether the drive is spinning:

  1. Boot the computer and listen carefully.
  2. Shut the computer down.
  3. Disconnect the power cord from the computer itself.
  4. Disconnect the power cable from the hard drive in question.
  5. Reconnect the power cord to the computer itself.
  6. Boot the computer up to see if the drive sound was audible before. And,
  7. Then repeat, only reconnect the hard drive and listen for it to spin up.
  8. Switch power cables with a device like a CDROM or DVDROM drive, so that you are using a known-good power cable.
  9. Check the power supply on your computer to determine whether it is providing sufficient electrical power to operate the drives and devices you have in your computer.
  10. If the drive is still not spinning, connect it in another computer if possible.
  11. Connect the drive in a SATA-USB enclosure or something similar if possible.
  12. If the drive does not spin up after all of these steps, please visit the Warranty page to begin a warranty replacement order.


  1. Incorrect jumper settings on the drive


ATA:  It is recommended that all Seagate ATA hard disks supporting the Cable Select jumper option be configured as Cable Select. If your computer system was built prior to October 1998 and does not support UDMA 66 or greater you will be required to use the Master/Slave jumper settings.

- -- (Click to expand) Jumper settings for Maxtor-brand ATA drives


When using Cable Select jumper settings on your ATA drive, all devices connected to the UDMA cable must also use the Cable Select setting. The cable decides master/slave device detection when the cable select jumper settings are used.


  1. Faulty Hard Drive

If you have completed the above checks and procedures and the drive is still not properly detected, please attempt to use SeaTools for DOS (see the tutorial here) to test the drive.  If SeaTools does not detect the drive after the steps followed above, or an error code that signifies drive failure displays, please proceed to the our Warranty Services page to begin a warranty replacement order.
