DiskMaster vs Scrutiny

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.

Scrutiny is a free, self-hosted dashboard for monitoring hard drive health through S.M.A.R.T. metrics. It records metric history and temperature, and allows customized thresholds based on real-world failure rates. Its collector uses smartctl to discover connected drives, and the project integrates with smartd. Failure notifications can be sent through email, webhooks, Discord, Gotify, Mattermost, ntfy, Slack, Teams, Telegram, and other listed services. Deployment choices include an all-in-one Docker image, separate hub-and-spoke Docker components, and manual installation; the hub-and-spoke setup stores S.M.A.R.T. data in InfluxDB 2.8. The repository lists Linux, macOS, and Windows binaries, while Windows Docker support remains in progress. For Docker, users must pass drive devices through and grant SYS_RAWIO; NVMe drives may also require SYS_ADMIN. Some RAID controllers do not pass underlying SMART data to smartctl. Manual installation instructions describe running the collector as an unprivileged user with restricted systemd permissions and network access. The project describes itself as a work in progress with rough edges and lists the MIT license.
