Download HD Tune for Windows PC v2.55 for Windows PC

HD Tune checks hard drive health, speed and surface errors in one tiny window: read benchmark, S.M.A.R.T.

Features

• The error scan checks every block on the drive and marks damaged areas red on a grid, giving a clear visual verdict on a failing hard drive surface.
• The Health tab reads S.M.A.R.T. attributes and drive temperature and summarises them in plain language, so early failure warnings are hard to miss.
• The read benchmark graphs transfer rate and access time across the whole drive, which quickly exposes a mechanical drive that is slowing down.
• The installer is only about 628 KB and the program itself is a single simple window, making it ideal to keep on a technician's USB stick.
• It is genuinely free for personal use with no time limit, unlike the Pro edition's 14-day trial sold on the same download page.

Considerations

• Version 2.55 is an old build: write testing, secure erase, folder usage and disk monitoring are reserved for the paid HD Tune Pro.
• SSD and NVMe reporting is basic, with none of the wear-level or percentage-used interpretation that modern SSD tools provide.
• A full error scan on a large multi-terabyte hard drive takes hours, and the free version adds no logging or scheduling to manage that.

HD Tune, from EFD Software, survives because it does the three jobs people actually open a disk tool for, in a single small window with one tab per job and no learning curve. The Benchmark tab graphs read transfer rate and access time across the whole drive — the classic curve that shows an ageing hard drive slowing toward its inner tracks. The Error Scan checks every block and paints damaged areas red on a grid (with a quick-scan option when time is short), so a failing surface is impossible to argue with. The Health tab reads S.M.A.R.T. attributes and drive temperature and summarises them as a plain OK-or-warning readout. It works with internal and USB-connected drives that Windows recognises as disks, and the whole installer is only about 628 KB, making it ideal to keep on a technician's USB stick.

Two editions share the official download page, and confusing them causes most disappointment. This listing is HD Tune 2.55, free for personal use with no time limit: read benchmark, error scan, drive information and S.M.A.R.T. health. HD Tune Pro — currently sold as the Pro 6.10 trial — is the separate paid product with a 14-day trial, and it reserves write benchmarks, secure erase, folder usage analysis and a disk monitor. If a feature you read about is missing here, it is almost certainly a Pro feature rather than a fault: the free version cannot run write benchmarks, securely erase a disk, show folder usage or monitor a drive over time. The free build is deliberately simple — and for a quick verdict on a second-hand drive, or a laptop that has started clicking and pausing, that simplicity is the point: it remains one of the fastest routes from question to answer.

Version 2.55 is an old build, and its age should be stated plainly. Its interface and drive reporting predate NVMe: SSD reporting is basic, showing raw attributes and temperature but none of the wear-level or percentage-used interpretation that modern SSD tools provide, so SSD wear indicators and modern controller details are better read in a newer or drive-vendor utility. A full error scan on a large multi-terabyte hard drive takes hours, and the free version adds no logging or scheduling to manage that. It also does not repair anything: HD Tune finds unreadable blocks and surfaces S.M.A.R.T. warnings, and the correct response to a growing error count is to back the drive up and replace it, not to keep scanning. Treat the free build as a quick health-and-surface checker for hard drives and basic SSD checks, not as a complete modern diagnostics suite. Requirements are minimal — Windows 7 to 11, 512 MB of RAM and 5 MB of space.

Download hdtune_255.exe, the free HD Tune 2.55 build, from EFD Software's download page using the button above — not the separate Pro trial installer listed next to it.

Double-click the downloaded EXE and follow the short setup wizard; the program is under a megabyte and installs in seconds.

Select a drive from the drop-down at the top, then use the Benchmark tab for read speed, Error Scan for a surface check, and the Health tab to read the S.M.A.R.T. status and temperature.

Is HD Tune free?

HD Tune 2.55 is free for personal use. HD Tune Pro is a separate paid product with a trial; the free 2.55 build listed here covers read benchmarking, error scanning, drive information and S.M.A.R.T. health reporting.

What is HD Tune used for?

HD Tune is used to benchmark a drive's read performance, scan its surface for errors, inspect detailed drive information and temperatures, and read S.M.A.R.T. health attributes. It works with internal and USB drives that Windows recognises as disks.

What software can I use to fix bad sectors on my hard drive?

HD Tune does not repair bad sectors itself. Its Error Scan finds unreadable blocks and its Health tab surfaces S.M.A.R.T. warnings; back up the drive immediately, because a growing number of errors usually means the drive should be replaced rather than trusted after a software workaround.

What is the best software for checking hard drive health?

HD Tune 2.55 is a good free basic check: it combines S.M.A.R.T. attributes, temperature, a surface error scan and a read benchmark in about a megabyte. Its reporting predates NVMe, so use a newer or drive-vendor utility when you need detailed SSD wear figures.
