01Command

Command

$ sudo hdparm -I /dev/sda

02What it does

hdparm -I queries the drive directly for model, serial, firmware, supported transfer modes and enabled features, which is useful when auditing hardware or diagnosing slow links. It is a low-level query that only the terminal exposes cleanly.
