The sector size is always 512 bytes according to the source. For the future, I am trying to get this interface documented.

Thank you for making that clear. I noticed that there's also a /sys/class/block/sda/queue/logical_block_size. I wasn't sure if I should use that, or the constant 512.

Usually compact disks have 2kB sectors. Adding hidden data, 2352 bytes.
