I would suggest that ddrescue should warn the user that their chosen
sector size is stupid.

The last two lines of the mapfile contain three numeric values which

Thank you for reporting this.
Note that the values above do make sense. They are multiples 0x100, a
valid value of sector size. Moreover, the positions and sizes of the
mapfile blocks are not required to be multiples of the sector size.
Note also that the 'current_pos' (0x142D3A80000) is in the middle of the
mapfile, indicating that ddrescue was already run on this mapfile before.
Maybe the user ran ddrescue previously with a --sector-size of 0x100.
Best regards,
Antonio.
