For SSDs, use Level 1 (read-only scan). SpinRite will read every logical block address (LBA) and report read errors, uncorrectable ECC events, or excessive retries. This helps identify failing flash cells without writing a single byte.
Long-time users will remember that older SpinRite versions had operation "Levels": spinrite v6.1
In v6.0, Level 4 was disabled due to architectural changes. In v6.1, Level 4 is back. This is the most powerful recovery mode for drives that are mechanically sound but have widespread magnetic decay. It writes a series of patterns (all ones, all zeros, alternating) to force the drive’s read/write head and platters to reorient magnetic domains. After the test, it restores your original data. For SSDs, use Level 1 (read-only scan)
Let’s be honest: SpinRite has always looked like it was designed in 1987. While v6.1 is still text-based (no bloated GUIs here), it now supports high-resolution text modes, mouse input (via USB), and a real-time graphical "heat map" of the disk surface. It shows you which sectors are healthy (green), marginal (yellow), or dead (red) in a scrolling visual grid. Long-time users will remember that older SpinRite versions
| Feature | SpinRite v6.1 | HD Tune Pro | DDRescue (Linux) | | :--- | :--- | :--- | :--- | | Works on NVMe | Yes (v6.1 only) | No | Yes (via kernel) | | Repair/Fix (Rewrites) | Yes (Automatic) | No (Test only) | No (Copies only) | | User Interface | Text (Easy) | GUI (Easy) | Command Line (Hard) | | Bootable | Yes (Standalone) | No (Requires OS) | Yes (Live CD) | | Price | $89 | $50 (Pro) | Free |
If you need a pure disk imager for a truly dead drive, DDRescue (Linux) is excellent and free. However, if you want to repair the drive so you can boot off it again, or if you want to maintain spinning rust, SpinRite v6.1 has no equal.
