You can also use the <code>-H<\/code> option to display a brief summary of the disk health:<\/p>\n<div class=\"bg-black mb-4 rounded-md\">\n<div class=\"flex items-center relative text-gray-200 bg-gray-800 px-4 py-2 text-xs font-sans\"><\/div>\n<div class=\"p-4 overflow-y-auto\"><code class=\"!whitespace-pre hljs language-bash\">smartctl -H \/dev\/twa0<br \/>\n<\/code><\/div>\n<\/div>\n<p>If the disk is healthy, the output will show that the disk is functioning properly. If there are any problems with the disk, the output will indicate the type of issue and its severity.<\/p>\n<p>It&#8217;s important to regularly check the health of your disks, especially those behind a RAID card, as disk failures can cause data loss and impact the availability of your systems.
