TestDisk

Maker: CGSecurity (Christophe Grenier) Platforms: Windows, macOS, Linux, BSD, Solaris, DOS

There's only one version of TestDisk — no tiers, no upsell, no separate "Pro" edition. Everything it does is available to everyone, for free, which is unusual on this page.

TestDisk

Repairs partition tables, recovers deleted partitions, fixes boot sectors, and can make a non-bootable disk bootable again — a command-line tool, not a wizard-driven app.

InterfaceText-based / command-line, no GUI
Current version7.2 (February 2024)

$0Free and open-source, always

TestDisk being free doesn't mean it's the easiest option — the command-line interface has a real learning curve compared to the wizard-driven consumer tools elsewhere in this directory. It rewards reading the documentation before running it on a drive that matters.
