Looks like you need to learn about CD writing basics.....
cdrecord knows how to write any possible sector type in -raw96r mode.
BTW: writing in -raw96r is a trick to circumvent problems from the
non-cooperative Linux hald (*) and -raw96 should be used with all Lite-ON
drives to circumvent firmware bugs found in all Lite-ON drives.
If you do not know how -raw96r works, then I would guess that your software
does not support to write in this mode.....
*) hald on Linux must be called harmfull software as it interrupts the write
process and makes media unusable. This is because it starts reading from
incompletely written CD.
