DiskMaster vs Macrorit Disk Scanner

DiskMaster is a free desktop application for monitoring drive health on Windows, Linux, and macOS. It reads SMART attributes, self-tests, and test logs, then calculates a health score out of 100 and shows which attributes account for deductions; performance has a separate score. It stores readings in SQLite and charts changes, with alerts for shifts such as increasing drive counters. A read-only surface scan times blocks, rereads unreadable sectors for confirmation, and maps them to sectors. DiskMaster can identify files associated with those sectors and try to rescue copies while skipping unreadable bytes. Optional repair tools include sector and filesystem repair, zero-fill, and sanitizing bad sectors the filesystem marks as free. Alerts can go to Slack, Discord, ntfy, email, desktop notifications, commands, or JSON webhooks. Its CLI exports text, HTML, JSON, and CSV reports. SATA and USB monitoring needs no third-party tools; NVMe health logs and macOS use optional smartmontools. Raw SMART access requires administrator or sudo privileges.

Macrorit Disk Scanner performs surface tests to find bad sectors on storage devices. It can scan a whole disk, a partition, free space or a selected area.

Unlimited Edition costs $99.95, paid once, covers an unlimited company license, supports Windows Server and includes multiple-disk scanning. A portable edition can run from a USB drive to scan offline disks. Listed supported storage includes HDDs, SSDs, hardware RAID, USB and external drives, flash drives, memory cards and other devices.
