What DiskWarrior is
DiskWarrior is paid macOS software that rebuilds damaged Mac disk directories using recovered directory data to restore access to files and folders. It optimizes and verifies the replacement directory and uses a fail-safe replacement method intended to protect against interruptions. A preview lets you inspect the expected repaired disk before writing changes, while S.M.A.R.T. monitoring can warn of possible hardware malfunction. DiskWarrior 5 supports Mac OS Extended disks, including journaled, case-sensitive, and encrypted variants. Recovery sources include internal and external volumes, Fusion Drives, Flash or SSD drives, Time Machine volumes, RAID volumes, disk images, and FileVault volumes. It supports Intel and Apple Silicon Macs and bootable recovery. APFS and Windows-formatted drives are unsupported, and deleted, reformatted, or overwritten data cannot be recovered. Pricing starts at $59.95.
