What should I be doing to my drives before building arrays with them? Hitachi do a Drive Fitness Test and Seagate something similar but I have not been able to get either to work on a BootCamp Windows partition. I tried formatting in Disk Utility and pulling some data on and off. I'm now running a scan for bad blocks in Drive Genius (is this worth it? It's going to take about a week at this rate). Anything else I should do?
