A value of 32 works for me with a Toshiba XM-6201B (256KB buffer). After installing the new kernel, you may use the -n sectors option to tell dagrab to read more sectors at once. I was wondering what file/value one would change to do this on FreeBSD, and what the overall implications of doing it were. Any help with this will be greatly appreciated.
