iRescueData Disk Diagnostics is a free tool that anyone can use to recover data. It is the first step in any data loss situation to determine the severity of drive failure. In many cases, it will recover files without requiring our lab services. It does this using a filesystem reader built for fault tolerance rather than speed. Consider it to be a safe mode for hard drives.
The project-based workflow shows you which files you already have as you browse your data folders. This allows you to select the most important files first as, very often, a failing drive will stop working altogether rather quickly.
Use iRDDiag on any computer running Windows XP or later. Bring the portable binary with you to work on other computers. Reads from internal or USB connected drives. Supported filesystems: NTFS, FAT, exFAT, APFS, HFS+, and EXT.
