In their own words
DiskMaster
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.
