Hello,

I would like to re-issue my earlier question:

Given the LBA (bad) block number of a disk drive, or the block number
of a partition, how can I tell which block on the /dev/mdX device
corresponds with it?

There is no easy answer.
You need to understand the layout of the array, and do some
arithmetic.
