the smart tools are *VERY* useful. I recently built a raid box and installed 5 of the disks in one nice fan-equipped bracket. unfortunately, 100G WD 7200 RPM's vibrate fairly seriously, and this actually caused horrible performance, as well as a small number of bad low-level writes and thus remapped sectors (shown by smartctl). simply moving some of the disks elsewhere entirely fixed the problem (120 MB/s!)
