Often when doing an radisk to search for bad blocks, the bad block number reported by the -s (scan) option is off by one (1) from the block number that the -c (clear error bit) option wants. In other words, if the scan reports that block 2345 (e.g.) is bad, I have to say "radisk -c 2344 1 /dev/rrd0c" to clear the error bit in the replacement block. Why the difference?
