From 5c55ac9bbca22ee134408f83de5f2bda3b1b2a53 Mon Sep 17 00:00:00 2001 From: Phillip Susi Date: Sat, 4 Feb 2006 23:27:48 -0800 Subject: [PATCH] pktcdvd: Allow larger packets 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.
