About SeaTools

SeaTools is Seagate's quick diagnostic utility for storage drives. It runs tests that check the health of a hard drive or SSD, which helps you decide whether a failing or noisy drive needs replacing before you lose data.

It is distributed from Seagate's support downloads section alongside the company's other drive utilities. It suits owners of Seagate drives and anyone who wants a straightforward health check from a drive manufacturer before sending a drive back under warranty.

Compare all

Software that can replace SeaTools for an important use case, and what changes if you switch.

  • CrystalDiskInfo

    Reads the health data your drives already record and tells you plainly whether one is dying.

    CrystalDiskInfo is MIT-licensed and gives a plain health verdict for drives of any brand, with NVMe support and tray alerts, rather than focusing on Seagate.

  • smartmontools

    Reads the SMART health data built into disks and runs self-tests, giving advance warning before a drive fails.

    smartmontools is open source for Windows, macOS and Linux, runs self-tests and schedules monitoring through smartd, but it is command-line only.

  • HDDScan

    A free Windows utility for testing hard drives and SSDs, reading SMART data and running surface tests.

    FreeProprietaryWindows

    HDDScan is free for Windows and adds read, verify and erase surface tests plus SMART and temperature readings across USB, RAID and SSD devices.

  • GSmartControl

    A graphical interface for smartctl that shows the health of hard drives and SSDs.

    GSmartControl is GPL-3.0 open source for Windows and Linux, highlights SMART anomalies and runs self-tests, relying on smartmontools being installed.

  • DriveDx

    A Mac utility that monitors SSD and HDD health through SMART data and warns before failure.

    PaidProprietarymacOS

    DriveDx moves the job to macOS, showing detailed SMART indicators, running self-tests and emailing reports, and it is paid after the trial.
