Using Seagate SeaTools: A Comprehensive Guide to Hard Drive Diagnostics

Ensuring the health of your hard drive is crucial for data integrity and system performance. Seagate SeaTools is a powerful, free diagnostic tool designed to help you test and analyze your hard drives, including those from Seagate, Samsung, and other manufacturers. Whether you suspect a failing drive or simply want to perform routine checks, this guide will walk you through how to effectively use the Seagate Scan Tool to diagnose and potentially fix hard drive issues.

Getting Started with SeaTools

Before you begin testing, you’ll need to download and install the SeaTools software.

Downloading and Installing SeaTools

Navigate to the official Seagate support website to download SeaTools. You can typically find it by searching for “Seagate SeaTools download” on any search engine or directly visiting the Seagate support downloads section.
Look for “SeaTools for Windows” which is compatible with Windows operating systems.
Download the installer file.
Once the download is complete, run the installer and follow the on-screen instructions to install SeaTools on your computer.

Launching SeaTools

After installation, you can launch SeaTools in a couple of ways:

Desktop Icon: If a SeaTools for Windows icon is present on your desktop, simply double-click it to launch the program.
Start Menu: If there’s no desktop icon, you can launch it through the Start Menu:
1. Click on the Start or Windows icon in the bottom-left corner of your screen.
2. Go to Programs or All Apps.
3. Find and select the Seagate folder.
4. Click on SeaTools for Windows to launch the application.

Preparing Your System for SeaTools Diagnostics

To ensure accurate and efficient testing, it’s important to prepare your system before running SeaTools.

Isolating SeaTools for Optimal Performance

It’s recommended to close all other applications before running hard drive diagnostics with SeaTools. This is because:

Focus Resources: Closing other programs ensures that your hard drive is primarily focused on SeaTools’ diagnostic commands.
Minimize Interruptions: Windows and other applications constantly access the hard drive for data. This background activity can interrupt SeaTools tests, causing them to take significantly longer to complete. While these interruptions are harmless, they extend the testing time unnecessarily.

Understanding Drive Identification

SeaTools can identify various types of drives connected to your system:

Internal Drives: These are drives installed directly inside your computer. SeaTools identifies internal drives as PATA (Parallel ATA or IDE), SATA (Serial ATA), SCSI, or SAS (Serial-Attached SCSI). Most modern desktops and laptops use SATA internal drives.
External Drives: These drives connect to your system externally via USB, Firewire (1394), or eSATA. External drives generally have less background activity compared to internal drives.

Managing Power Settings for Long Tests

Longer SeaTools tests, especially comprehensive scans, can take several hours. To prevent interruptions, you need to adjust power management settings:

Click on the Start or Windows icon.
Open the Control Panel.
Select Power Options.
Find the power plan settings and look for “Turn off hard disks” or similar options.
Change this setting to “Never” while running SeaTools tests. This prevents the system from entering Standby or Hibernate modes during long scans, which could interrupt the diagnostic process.

Powering Laptops Correctly

If you are using a laptop, it’s crucial to connect it to a power outlet using the AC adapter.

Avoid Battery Power for Long Tests: Diagnostic tests are disk-intensive and consume more power than typical laptop usage. Running long tests on battery power alone is not recommended as it can drain the battery quickly and potentially interrupt the test if the battery level becomes too low. Ensure your laptop is plugged in to provide consistent power throughout the testing process.

Selecting the Drives to Test with SeaTools

Once SeaTools is launched, the main screen will display a list of all detected storage devices in your system.

Drive Selection: To select a drive for testing, simply check the box next to the drive information. You can identify your drives by their model number and serial number displayed in the list. Seagate model numbers typically start with “ST,” and Seagate serial numbers are alphanumeric and eight characters long.
External Drive Considerations: Be aware that for external drives, SeaTools might sometimes display the serial number and model number of the internal drive within the external enclosure, rather than the external unit itself. For accurate identification of external drives, always check the physical label on the drive itself. For more help on locating model and serial numbers, Seagate provides a helpful Knowledge Base article.
Drive Icons: SeaTools uses icons to visually differentiate drive brands. Seagate, Samsung, LaCie, and Maxtor drives are represented with a gold drive icon, while non-Seagate drives are shown with a silver icon.
Testing Multiple Drives: SeaTools allows you to select and test multiple drives simultaneously, which can be useful if you need to diagnose several drives at once.

Running Diagnostic Tests with Seagate Scan Tool

After selecting the drive(s), SeaTools presents a menu of diagnostic tests. All “Basic Tests” are data-safe and read-only, meaning they will not modify or erase any data on your drive.

Available Diagnostic Tests

The Basic Tests menu typically includes:

Fix All: This option attempts to automatically repair any detected issues. It has “Fast” and “Long” versions. Important: Back up your data before using “Fix All” as data in bad sectors may be lost during repair.
Short Drive Self Test (DST): A quick diagnostic test (20 to 90 seconds) that is built into most modern hard drives’ firmware. It’s data-safe and often sufficient for initial checks.
Drive Information: Displays detailed information about the selected drive, such as model number, serial number, firmware version, and capacity.
Short Generic: A more comprehensive short test that checks various areas of the drive for errors.
Long Generic: A thorough, sector-by-sector scan of the entire drive. This test can take several hours depending on the drive’s capacity and speed. Progress is shown in 1% increments.

Understanding Test Types and When to Use Them

Short Drive Self Test (DST): Ideal for a quick initial assessment of drive health. It leverages the drive’s built-in diagnostics and is very efficient.
Short Generic: Use this test for a slightly more in-depth check than DST. It tests various parts of the drive and can identify common issues.
Long Generic: Choose this test for a comprehensive examination, especially if you suspect more serious problems or want to thoroughly check the entire drive surface. Be prepared for a longer test duration.
Fix All Tests (“Fast” and “Long”): These options are designed to repair logical bad block addresses (LBAs), also known as bad sectors.
- Fix All Fast: Quickly checks drive activity logs for potentially bad sectors and attempts to reallocate them. It’s faster (usually under 5 minutes) but may not be as thorough.
- Fix All Long: Performs a complete sequential scan of the drive media, identifies bad sectors, and attempts to reallocate them. This is a much longer process (approximately 3 hours per terabyte) but more comprehensive in its repair attempts. Always back up your data before running any “Fix All” test. Data in bad sectors is typically unrecoverable.

Upon completion of any diagnostic test, SeaTools provides a summary of the results.

Understanding Test Status

The test results are indicated by different statuses:

Passed: Indicates that no errors were detected during the test.
Failed: Indicates that SeaTools found errors or issues with the drive.
Aborted: Shows that the test was manually stopped before completion.

Example of SeaTools test result statuses: Passed, Failed, and Aborted.

Accessing Log Files and Detailed Information

SeaTools saves a log file for each test run in the program’s installation folder. You can access these logs by:

Clicking on Help in the SeaTools menu.
Selecting View Log File.

Additionally, after a test completes, you can often see quick result summaries directly in the SeaTools interface.

Pass Info/Fail Info: Depending on the test outcome, buttons labeled “Pass Info” or “Fail Info” will appear next to the “Help” option. Clicking these provides a summary of the test results.
Tabs for Detailed Results: Clicking on “Pass Info” or “Fail Info” typically opens a window with three tabs: “Pass Info” (or “Fail Info”), “Warranty Checker,” and “View Log File,” offering different levels of detail about the test and drive.

Troubleshooting and Next Steps Based on SeaTools Results

Addressing a “Pass” Result

A “Pass” status from SeaTools is generally good news, suggesting your hard drive is functioning correctly from a hardware perspective.

Software or Data Issues: However, a “Pass” does not rule out all problems. Your drive might still have corrupted data or software-related issues. If you suspect data corruption, consider running Windows’ built-in chkdsk utility. If chkdsk fails to repair issues, you may need to reinstall software, restore data from backups, or attempt data recovery.

Handling a “Fail” Result

A “Fail” status indicates that SeaTools has detected problems. The severity and next steps depend on the test and the type of drive.

External Drives and “Fix All Long”: If you get a “Fail” result on an external drive connected via USB or Firewire, consider running the “Fix All Long” test option. Ensure you have backed up all important data first.
Data Recovery: Be aware that “Fix All” operations can make data recovery from bad sectors impossible. If you haven’t backed up your data and cannot afford to lose it, contact Seagate Recovery Services or another professional data recovery service before running “Fix All.”
Warranty Check: If SeaTools fails to repair bad sectors, or if the drive fails repeatedly, check your drive’s warranty status. You can do this on the Seagate Warranty Validation page. You will need your drive’s serial number for the warranty check.

SeaTools for DOS for Internal Drives

For internal PATA (IDE) or SATA drives, especially those with operating systems installed, consider using SeaTools for DOS for more efficient “Long Test” and “Fix All” operations.

Bootable Environment: SeaTools for DOS runs from a bootable CD or USB drive, outside of the operating system. This allows for faster testing and repair as the drive isn’t being actively used by the OS.
Creating a Bootable Disk: You can find the SeaTools for DOS ISO file within the SeaTools for Windows installation folder. Burn this ISO to a CD or create a bootable USB drive.
Booting from SeaTools for DOS: Boot your computer from the created CD/USB and run the “Long Test” in the DOS environment. SeaTools for DOS will also offer to repair bad sectors if found.

Remember, Seagate SeaTools is a valuable tool for diagnosing potential hard drive issues. By following these steps and understanding the test results, you can effectively maintain your drive’s health and protect your valuable data. Always prioritize data backup and consider professional help when dealing with drive failures and data recovery.
