pktcdvd: Allow larger packets From: Peter Osterlund From: Phillip Susi The pktcdvd driver uses a compile time macro constant to define the maximum supported packet length. I changed this from 32 sectors to 128 sectors because that allows over 100 MB of additional usable space on a 700 MB cdrw, and increases throughput. Note that you need a modified cdrwtool program that can format a CDRW disc with larger packets to benefit from this change.
