where:
b = File System block number
B = File system block size in bytes (dumpfs 16384)
L = LBA of bad sector
S = Starting sector of partition as shown by fdisk
and (int) denotes the integer part.
S = 0、B = 32768、L = 3899544120を公式に代入。
b = (int)(3899544120 * 512 / 32768) = (int) 60930376.875 (小数点以下切捨)
