If you don't have console access, run the /sbin/dmesg command. If you see any ad2 read errors from the console, then you likely have a bad drive. On the other hand, if you don't see any errors being reported by the kernel, then the "CANNOT READ" errors are probably just caused by incompleted meta-data writes to the drive. However, "THE FOLLOWING DISK SECTORS COULD NOT BE READ" makes me think it is a hardware problem. > 2) Are there any BSD tools for reading the SMART data off the Hard Disk > so that I can see whether it is about to fail or currently experiencing > HW failure.

I'm honestly not sure if anything like that is available. Searching the FreeBSD site did not yield any results. My best suggestions is to check google.
