  2. I am attempting a new installation of the Solid State Drive in my notebook/laptop PC and it is not detected correctly.
  3. My Solid State Drive's capacity is lower than I expected.
  4. Error messages
  5. I want to know how to optimize my Solid State Drive's performance and longevity.

Introduction to Troubleshooting

Generally, if a SATA drive is configured as the bootable drive, then the computer relies on that drive to boot the computer and to launch Windows. It is the source of most of the computer's operations. So, if the computer suddenly stops detecting the bootable drive, this will almost certainly mean that the computer will fail to boot at all. Instead, some error message will occur, and it will become obvious that a serious problem has occurred.

This set of troubleshooting steps will attempt to get the drive detected again, or to conclude whether the drive has failed and should be replaced.

One error in particular, however, is more important than others to watch out for. If a "SMART error" has recently appeared on your computer, this generally means drive failure is imminent or has already occurred. If you have received a SMART error, we strongly recommend that you stop everything and make an immediate backup of any and all important data contained on this drive that is not already backed up.

BIOS

The BIOS is a basic status monitor for the state of your computer and its devices.

Access the BIOS by rebooting the computer and, while it is in the process of booting, before the Windows screen appears, press the key that will open the BIOS. This key will vary by computer make and model, but it is often Escape, Delete, F1, or F2. Consult your computer manufacturer if you are unable to enter the BIOS.

Here are a few tips:

  • Sometimes the reboot will proceed too quickly for you to be able to press the BIOS key in time. In this case, shut down the computer and wait for it to cool a little (probably at least 5 minutes). Then boot the computer again and retry.
  • See this webpage for more tips on dealing with your BIOS.

Please keep in mind that these contain information that has not been fully verified by Seagate, nor does Seagate possess in-depth nor exhaustive knowledge of your motherboard BIOS, since the BIOS is the property of a different company.

For the most specific and up-to-date information about the BIOS (which is the domain of your motherboard), please check the website of and/or contact the manufacturer of the SATA motherboard.

Most new computers will automatically detect devices through the system setup program (CMOS or BIOS). As the system starts, the auto-detect feature may display the drive model number on screen. Seagate drive model numbers begin with the letters "ST".

Some Serial ATA BIOS have a system setup that is not contained within the normal motherboard BIOS. If this is the case, the Serial ATA drive will only be displayed in this Serial ATA BIOS message. Please consult the motherboard or Serial ATA controller documentation for assistance with entering into the Serial ATA BIOS setup.

Does a backup exist?

Is the data on this drive backed up elsewhere, or do you need to try to recover it?

    Please select an answer:
  1. Backed up elsewhere / I do not need to recover the data.
  2. I need to recover the data

Alternative Installations

Since the drive is not detected in the BIOS, you can attempt to access and perform diagnostics on the drive in one of two ways:

    Please select an answer:
  1. Install the drive in an external enclosure and connect the drive via USB to a second computer (of any kind)
  2. Connect the drive in a second computer (for troubleshooting purposes, this can be either a notebook or desktop computer with a Serial ATA interface)

Try a Second Computer

If you have access to another notebook of similar type and specifications, you can (after powering down the computer, of course) replace the computer's hard drive with the hard drive you are trying to recover.

  1. Once the connection of the problem hard drive is complete, boot up the computer to test the drive's behavior. If it boots normally, that is a good sign.
  2. Whether it boots correctly or not, boot to Seagate's SeaTools for DOS to run short and long drive self tests on the drive.
    1. Click here for more information on what the tests reveal at the SeaTools error messages section of this troubleshooter.
  3. If the diagnostics reveal no problem, then the booting problem means a different problem in your original notebook computer. We recommend you contact the notebook manufacturer for further support at this point.
  4. If it does not boot normally, then we must continue troubleshooting.
    Check in the BIOS again, repeating the same steps as before.
    1. Click here if it is detected in the BIOS but does not boot correctly.

    If it is not detected in the BIOS of this second computer, there is no more troubleshooting to be done beyond replacement.
    Please replace the drive. Please contact Seagate Recovery Services for assistance in recovering your data.

Once your drive is replaced, please install it according to the included instructions, and see Document ID: 005712 - How to get the most out of Solid State Drives in Windows for best practices.

Corrupted Operating System

At this point, the most likely reason why the drive stopped booting correctly is a corrupted operating system.

Since your data is already backed up or you do not need the data, insert and boot from your Windows install disc to perform a Windows Repair/Restore.

  1. Boot up the computer.
  2. Insert your Windows installation CD/DVD into the CD/DVD drive.
  3. Reboot the computer, and it should boot up into the Windows disc.
  4. Select to perform a repair or restore action, and follow the steps provided there.
  5. If the repair or restore fails, the following articles may be of assistance.

Windows Vista Startup Repair: frequently asked questions

If the drive successfully passes the diagnostics (but the Windows repair/recovery failed), then the drive itself is most probably safe to continue using. You should therefore attempt to erase the drive and reinstall the operating system.
The simplest way to reinstall the operating system (and probably erase the data, though that does not happen every time) is to insert the Windows CD/DVD in the CD/DVD drive and then reboot the computer. The option to repair Windows should appear as well as an option to reinstall Windows. Since the repair has failed, simply choose to reinstall Windows.

*NOTE: This will very probably erase all data on the drive.

If that fails to reinstall Windows, a stronger erase is probably required. Seagate's utility SeaTools for DOS can perform a quick, a timed, or a full erasure (known as a "zero-fill") of the drive. In this case, a full zero-fill is probably the best option. This can take many hours depending on many factors including the drive capacity, so leave adequate time for this. If you are short on time, attempt a timed zero-fill of at least a few minutes.
Then insert the Windows CD/DVD in the CD/DVD drive and then reboot the computer. You should be able to install Windows as if from scratch.

Try An External Enclosure

If connecting the drive in another computer did not allow you to access the data, or if you do not have another computer available, you can connect the drive via an external enclosure or adapter that will connect to the computer from one of the USB ports on the outside of the computer.
You will need:

  • a working computer; it can be either a desktop or a notebook
  • an external USB enclosure
    A USB enclosure or SATA-USB connection adapter can be found at many computer stores and is inexpensive.
  • two storage media for backing up your data - internal hard drive, external hard drive, CD, DVD, online storage, tape, or some combination.
  1. Connect the drive inside the enclosure or to the adapter according to the manufacturer's instructions.
  2. Power on the drive and enclosure, and connect it to the computer via USB. The computer can be powered on when you do this.
  3. The drive should appear in (My) Computer and/or Windows/File Explorer.
  4. If the drive is not detected, follow the steps of our external drive troubleshooter to see if you can get the drive detected.
    If the drive is still not detected, there is no more troubleshooting to be done beyond replacement.
    Please replace the drive.

Once your drive is replaced, please install it according to the included instructions, and see Document ID: 005712 - How to get the most out of Solid State Drives in Windows for best practices.

  1. Please click here if the drive is detected normally in (My) Computer and/or Windows/File Explorer when installed in this external enclosure.

Check for Legacy Equipment

If the drive is detected normally in (My) Computer and/or Windows/File Explorer when installed in this external enclosure, this means the drive is healthy.

However, since we already tested the drive in the original computer and it was not detected even at the most basic level, the BIOS, the source of the problem is either a limitation or another problem with the first computer.

Some older notebook computer motherboards use the original Serial ATA interface at 1.5Gbits/sec speed, also known as SATA-1. If your computer has the SATA-1 interface, it may be inconsistently compatible with your Seagate Solid State Drive. Check with the computer manufacturer for more information.

If, however,

  • your notebook computer uses a more modern Serial ATA interface, and
  • the SSD previously functioned correctly, and
  • the SSD still functions correctly when installed in a different configuration,

then the source of the problem is most probably the first computer. Please contact the manufacturer for troubleshooting assistance.

Alternative Installations

Since the drive is not detected in the BIOS, unfortunately the chance of recovering the data is lower than otherwise. You can attempt to access and perform diagnostics on the drive in one of two ways:

    1. Click here if it is detected in the BIOS but does not boot correctly.
    2. Click here if it is not detected in the BIOS of this second computer.
  • Make a Backup

    To return the drive to proper working order, we must attempt to repair or reinstall Windows. This will result in erasing the data on the drive.
    Before putting your data at risk, you should make a backup.

    The easiest way to do that is to connect the drive via an external enclosure or adapter that will connect to a different computer from one of the USB ports on the outside of the computer.
    You will need:

    • a working computer; it can be either a desktop or a notebook
    • an external USB enclosure
      A USB enclosure or SATA-USB connection adapter can be found at many computer stores and is inexpensive.
    • two storage media for backing up your data - internal hard drive, external hard drive, CD, DVD, online storage, tape, or some combination.
    1. Connect the drive inside the enclosure or to the adapter according to the manufacturer's instructions.
    2. Power on the drive and enclosure, and connect it to the computer via USB. The computer can be powered on when you do this.
    3. The drive should appear in (My) Computer and/or Windows/File Explorer.
    4. Begin the backup action. If you are backing up the data to a different external drive, you may simply drag and drop.
      Creating two different complete backups of your data, on two different storage media, is strongly recommended.
    5. Once the backups are complete, proceed to the next step.

    Check For Legacy Equipment

    If the drive is detected normally in (My) Computer and/or Windows/File Explorer when installed in this external enclosure, this means the drive is healthy.

    First Steps

    Once you connect a new SSD in your notebook computer, there remains more to do to get your drive working.

    First of all, often, users want to install a new drive in order to upgrade to a larger hard drive in their notebook. This usually means that the user wants to copy all the data from the older hard drive to the newer SSD, then install the SSD as the bootable drive. To upgrade to a new notebook drive, copying your data from the old drive to an SSD, see our article on copying data from one notebook drive to another.

    See also Document ID: 205075 for more information on installing notebook drives and Document ID: 005708 about the proper drivers in Windows.

    Windows Installation

    If you are simply going to install a new copy of Windows (the operating system), you first need to format and partition the drive, and then install Windows:

    1. Insert your Windows installation CD/DVD into the CD/DVD drive of your computer.
    2. Power down the notebook.
    3. Install the drive physically into the notebook.
      See also Document ID: 205075 for more information on installing notebook drives.
    4. Boot up the notebook.
    5. The Windows installation process should begin, as the computer boots from the installation CD/DVD.
    6. Follow the guidance of the install program.
      It will take you through a process of several steps, including partitioning and formatting the drive. You can choose the default setting - one big partition - or choose to partition the drive into multiple different partitions, as you prefer. It will then install Windows.
    7. Once it is complete, it will most probably ask you to remove the CD/DVD and reboot the computer. Once this is done, you should be able to boot into Windows, and the install is complete.

    BIOS

    The BIOS is a basic status monitor for the state of your computer and its devices.

    Access the BIOS by rebooting the computer and, while it is in the process of booting, before the Windows screen appears, press the key that will open the BIOS. This key will vary by computer make and model, but it is often Escape, Delete, F1, or F2. Consult your computer manufacturer if you are unable to enter the BIOS.

      Please replace the drive.

    Once your drive is replaced, please install it according to the included instructions, and see Document ID: 005712 - How to get the most out of Solid State Drives in Windows for best practices.

    Check For Legacy Equipment

    Since the drive is properly detected in the second computer, and if it passed the diagnostic tests performed during the previous step, the source of the problem is either a limitation or another problem with the first computer.

    Some older notebook computer motherboards use the original Serial ATA interface at 1.5Gbits/sec speed, also known as SATA-1. If your computer has the SATA-1 interface, it may be inconsistently compatible with your Seagate Solid State Drive. Check with the computer manufacturer for more information.

If your computer has the SATA-1 interface, it may be inconsistently compatible with your Seagate Solid State Drive. Check with the computer manufacturer for more information.

    If, however,

    • your notebook computer uses a more modern Serial ATA interface, and
    • the SSD previously functioned correctly, and
    • the SSD still functions correctly when installed in a different configuration,

    then the source of the problem is most probably the first computer. Please contact the manufacturer for troubleshooting assistance.

    Lower Capacity

    If your Solid State Drive is displaying a lower capacity than you believe was advertised, please see Document ID: 194563 for all relevant information.

    Error Messages Menu

    What error message is displaying?

    Black Screens

    See Microsoft Knowledge Base Article 314503.

    Alternately, this could be caused by the bootable drive's having failed or gone undetected . You may need to begin troubleshooting at the first step of the troubleshooting procedure for bootable drives.

    SMART Error Messages Menu

    Under what circumstances did the SMART error occur?

    SeaTools

    Seagate uses the SeaTools diagnostic software to test the SMART status of the drive. It also dives deeper to test the drive on other levels.

    SeaTools' PASS or FAIL is the standard that Seagate uses to determine whether a hard drive is still in good working order, or is failing. A drive may be failing but continue to function normally for a short time, so SeaTools is often a better judge of whether the hard drive is failing than the drive's functionality at any given moment.
    Therefore, if SeaTools indicates that the drive is failing, Seagate recommends backing up your data immediately and replacing your drive.

    Please see our Warranty Information page for replacement information.
    See Document ID: 203971 for more information on SMART errors.

    SMART Error Information

    Each Seagate hard drive engages in regular self-tests, and most computers automatically run regular SMART tests on the hard drive(s) installed on them. SMART tests indicate whether a drive is approaching imminent failure. Thus, if a SMART error appears suddenly, it virtually always means, unfortunately, that the drive is about to fail and should be replaced.

    See Document ID: 184619 on SMART errors and Document ID: 203971, on the difference between third-party SMART monitoring programs and Seagate's SeaTools for more information.

    See our Warranty Information page for help replacing a failing drive.

    Third-Party SMART Tests

    Please see Document ID: 203971 having to do with third-party SMART programs.

    Delayed Write Failure

    If you encounter a delayed write failure, please check the following things:

    1. Confirm the cable is firmly connected to the drive.
    2. If the drive cables come loose repeatedly, use locking SATA cables or reposition the drive in the case so that pressure/tautness on the cable is reduced.
    3. If the problem continues, consider replacing your SATA cable.
    4. Confirm you are using the current SATA driver from the manufacturer of your SATA motherboard/controller. See Document ID: 005708 for more information.
    5. Test the drive using SeaTools for Windows or SeaTools for DOS.

    SeaTools

    SeaTools tests Seagate Solid State Drives for electronic and mechanical well-being and gives a PASS or FAIL result.

    A FAIL result means two things:

    1. You should make sure your data is completely backed up. Please contact Seagate Recovery Services for assistance in recovering your data.
    2. You should replace the drive.

    Please see Document ID: 206595 for more information on related error messages.
