Find All Connected Harddisks

Tagged with: , , , , , , ,

<p class=”intro”>If you have many IDE harddisks connected to the system(but not mounted), this command will find it. This will work for sata HDD as well if you use ‘sd’ instead of ‘hd'</p>

<pre><code class=”cli”>
ls /dev/hd*
</code></pre>

<p>Simple, is it not? To find the mounted drives just use the command ‘dh’.</p>
