Best SeaTools Alternatives

It’s important to ensure your HDD and SSD drives are in good health. If they’re not, you’re at risk of losing all the data they contain if they get completely damaged.

With a tool like SeaTools, you can monitor your drives and stay informed on their health. There are several other software programs like SeaTools and in this post, we’ll be looking at those alternatives.

Why You Should Use A SeaTools Alternative

The SeaTools for Windows software is a reliable one. However, there are different situations where you may need an alternative software to diagnose and test your drives.

Notably, SeaTools is a free-to-use software. Hence, you’re likely to find more features with a premium or freemium disk diagnostic tool compared to SeaTools.

Likewise, most users have complained that the SeaTools software isn’t portable. This is because the software requires .NET 4 framework, which consumes space and relatively takes time to install/update.

Furthermore, SeaTools is a Windows software so you’ll need an alternative if you use a Mac, Linux, or another major operating system.

Below are the 10 best SeaTools alternatives.

10 Best SeaTools Alternatives


CrystalDiskInfo is a system utility software that ensures your hard drive is in good health. It uses SMART technology and can detect possible errors on your hard drive before they occur, so you can take necessary precautions to avoid data loss.

Just like SeaTools, the CrystalDiskInfo software also serves information. When used, you can view all information about your hard drive such as its firmware, cache size, brand, model, serial number, etc.

With CrystalDiskInfo, it’s hard to miss any possible error on your hard disk. This is because the software uses different color schemes to rate how bad or good your hard disk is. Hence, this makes CrystalDiskInfo a little more convenient to use than SeaTools.

If your hard disk is bad, you’ll get a red color, while you’ll get yellow for caution, and blue if it’s in a good state. Sometimes, the software is unable to analyze the health state of your hard disk and you’ll get the gray color.

Both CrystalDiskInfo and SeaTools support checking of external drives like USB drives. CrystalDiskInfo also supports checking of controllers including Microsoft, AMD, Intel, NVIDIA, etc.

This software supports event logs allowing you to keep track of all your disk checking activities. SeaTools doesn’t support Alert Mail but CrystalDiskInfo info does. With this feature, you’ll get an email whenever the system detects any major error in your hard disk. However, to use the Alert Mail, you must have the .NET Framework 2.0 or a later version; SeaTools requires version 4 or later.

CrystalDiskInfo info works only on Windows, just like SeaTools. Also, with an MIT License, the software is free to use.


First released in 2008, this software is a graphical user interface for controlling SMART data on the hard disk and other drives. It’s a software off the smartmontools package. GSmart is recommended as a SeaTools alternative as it does the job, is fast, and is not difficult to use.

As software that supports SMART data, you can use GSmartControl to inspect your hard disk health and determine its state. Also, you can run various tests on your hard disks using this software to get results. The software interface is somewhat native but reading information off it is seamless. It features a temperature log, physical, directory, and error recovery tabs.

A notable feature of GSmartControl is the Automatic Offline Data Collection. The software performs a soft check on your drive every four hours. This is done automatically and won’t impact your PC performance in any way. However, you can disable this feature.

GSmartControl performs SMART self-tests but the software also allows you to enable or disable SMART. Apart from the hard disk, you can also check various USB and controller devices for errors. Once an issue is detected, you get an automatic report so you can take the quickest action.

GSmartControl is a free hard disk monitoring tool like SeaTools but, while SeaTools is proprietary, GSmartControl is open-source software. Hence, if you’re a programmer, you can do more with GSmartControl than with SeaTools.

Furthermore, SeaTools supports just Windows, while GSmartControl supports Windows, Linux, Mac, and FreeBSD. Therefore, if you don’t use Windows OS, GSmartControl is the ideal SeaTools alternative to consider. However, installation on other operating systems aside from Windows OS is very technical.

HD Tune

HD Tune is a multi-functional hard disk and SSD utility software program. It was launched in 2008 by EFD Software Company. The software will work on external and internal hard disks, SSD, USB Sticks, and memory card readers.

Basically, HD Tune can scan your hard disks and other drives for errors, measure their performance, check their SMART health status and securely wipe all data.

As a multi-functional software, you can do a lot more with HD Tune than with SeaTools. This includes advanced features like AAM setting, write benchmark, file benchmark, command line parameters, and folder usage view, amongst others.

This tool has an interface similar to Windows native tools. SeaTools has a relatively friendlier user interface, but you still won’t have difficulties navigating through the HD Tune Environment.

HD Tune is a good hard disk utility software, but you can do more with the HD Tune Pro version. With the normal version, you can perform functions like disk monitoring, secure erase, SMART self-tests, check the status of multiple drives, etc. Meanwhile, you can do all of these with the HD Tune Pro version.

This software is ideal if you’re looking for a lightweight SeaTools alternative. The SeaTools software for Windows is about 26 MB in size meanwhile HD Tune is just 628 KB – less than 1 MB. The HD Tune Pro is lightweight too as the file size is just about 2.2 MB. Like SeaTools, you can only use HD Tune on Windows.

HD Tune Pricing

HD Tune is a free-to-use software. However, the HD Tune Pro version is premium.
