Sparable partitions provide a defect-managed partition
space for media that does not implicitly provide defect management,
such as CD-RW. Arbitrary packets of blocks in the sparable partition
may be transparently remapped to other locations on disc should the
original locations become defective.
Per UDF-2.01 2.2.11, sparable partitions shall be recorded only on
disk/drive systems that do not perform defect management.
See also UDF-2.01 2.2.9, UDF-2.01 2.2.11
