Currently dvd+rw drives and media support true random sector writes, and so a udf filesystem on such devices can be directly mounted read/write. CD-RW media however, does not support this. Instead the media can be formatted for packet mode using the utility cdrwtool, then the pktcdvd driver can be bound to the underlying cd device to provide the required buffering and read-modify-write cycles to allow the filesystem random sector writes while providing the hardware with only full packet writes. While not required for dvd+rw media, use of the pktcdvd driver often enhances performance due to very poor read-modify-write support supplied internally by drive firmware.h]hXWrite support requires a block driver which supports writing.
