yeh, I originally was using block for a while, and ONE of my drives
didn't support it, then I switched to phys, and haven't had a problem..
and I have quite a range of drives:
hydrogen,ttyq3,~,502$grep 'Direct Access' /var/run/dmesg.boot
da3: <FUJITSU M2654S-512 010O> Fixed Direct Access SCSI-CCS device
da0: <MICROP 4421-07 0329SJ 0329> Fixed Direct Access SCSI-2 device
da5: <IMPRIMIS 94601-15 4614> Fixed Direct Access SCSI-CCS device
da6: <FUJITSU M2654S-512 010O> Fixed Direct Access SCSI-CCS device
da2: <SAMSUNG WN32162U 0100> Fixed Direct Access SCSI-2 device
da1: <MICROP 4743 S150> Fixed Direct Access SCSI-2 device
da4: <MICROP 4743 S150> Fixed Direct Access SCSI-2 device
which is a selection of scsi-1 (scsi-ccs), fast scsi, and ultra scsi
drives... I'm sure that just using phys will keep all drives usable..
and if the user wants a different format, they can manually run
camcontrol...
bad disk blocks SHOULDN'T appear that often... :)

something like:
`awk '$1 ~ /(da|sd)'"${i}"'/ { type = $2 } END { if (type == "" ) echo "phys"; else echo type; }'`
should do perfectly fine... :)
