A lot of ST32000542AS drives come with the CC34 firmware. Apparently it has various known problems, one of which is an annoying click (click of death). The first thing you’ll want to do is upgrade the firmware to CC35. A Link to the instructions is in the references section below.
Once that is done, the next step, if it exists, is removing HPA from the drive.
You’ll know it has HPA enabled by running hparm. HPA results in less capacity and so it’s not a good thing in an array.
We’ll be using Debian 6.0 (squeeze).
hparm -N /dev/sdb
