It's reasonable to start with something like a:
dd if=/dev/your_disk of=/dev/null bs=5120
...to at least try reading every sector on the drive as a basic
sanity check. Better would be to install /usr/ports/sysutils/
smartmontools and run some SMART self-tests via:
smartctl -t long /dev/your_disk
smartctl even understands some types of RAID controllers, but not all
of them....
