Greetings, I have a hard drive that every now and then makes a sound like the head is moving from one extreme to the other, then parking. It is hard to explain, kind of a towk-kok-click with a metallic ring to it. If you have heard a drive do this before, you know the sound. I heard a drive do this to me a few months ago and it failed shortly thereafter. I have 3 drives in the system so it is very hard to know which drive it is, so in an attempt to get a new drive before the one fails out right, is there any way I can test the drives in place? One drive is primarily my system disk (20G), the second (120G) has /usr mounted on it, and the third (120G) is mounted, rsync'd, umounted every night to make a backup of the other two. So, the backup drive I can test no problem, even destructively if necessary. However, the two that make up the active system I would like to be able to test without disrupting normal operation if possible? But, I'll take the box offline for a bit if necessary. Any insight would be greatly appreciated. Thank you, Matthew
