smartmontools

smartmontools at a glance

smartmontools provides the smartctl and smartd tools for monitoring drive health via S.M.A.R.T. on Linux, Windows and more — a staple for catching failing disks early. It ships releases in an unhurried cadence plus updates to its drive database.

For admins smartmontools is low-risk and read-only with respect to your data, so the update driver is drive-database coverage and features rather than security. Keep it reasonably current so it recognizes newer SSDs and NVMe drives and reports attributes correctly, and configure smartd to alert on impending failures — that proactive warning is its whole value. It usually comes from the distribution. After updating, verify that smartctl reads your drives and smartd notifications work. In fleets, feed its output into central monitoring. Replacing a drive before it dies is far cheaper than a rebuild — keep the monitoring active and current. Patchletter surfaces new smartmontools releases so drive support stays current.
