What SpinRite is

SpinRite is a storage maintenance program that scans magnetic and solid-state media to check and improve data readability. Its maker says it attempts to recover unreadable or barely readable data and rewrite what it recovers to the storage device. It can refresh solid-state media, and the maker recommends an annual run on SSDs. SpinRite also monitors SMART feedback while reading and writing. It works with mass-storage devices regardless of operating system or file system, but version 6.1 is a DOS application. Its executable runs under Windows to create bootable media, which launches the program with FreeDOS. Version 6.1 requires an Intel or AMD PC with BIOS or compatible firmware; it does not run on ARM PCs or systems without BIOS support. USB connections can be used, though direct PATA or SATA connections are preferred. GRC estimates about two hours per terabyte for modern directly connected SATA drives and warns that large drives may take a long time. SpinRite v6.1 costs $89 one-time, with no free plan.

Who it suits

SpinRite may suit people maintaining or attempting data recovery on compatible Intel or AMD PCs with BIOS support. Users should account for its DOS boot requirement and potentially long scan times.

What it does well

  • Requires BIOS or compatible firmware.
  • Large drives can take a long time.

Limits
