Your program has been written under incorrect assumptions (the sector size is
definitely not 2048 bytes), so it cannot work.

But you cannot simply increase your sector size, as there is a mix of different
sector types with different sector sizes. I suspect that you don't know the
high level structure well enough to know which sectors uses which
type/sectorsize and it is highly improbable that the device driver supports to
switch automagically to use the right SCSI commands in order to read the
specific sector types.

The right way to read such a CD is "readcd". It sends it's own SCSI commands
and for this reason does not depend on missing features in the driver.

I recommend "man readcd" and to use readcd -clone
