dd command to view raw disk data

I want to look at raw data on an optical disk but this only gives a 4k dump:dd if=/dev/sip/t0d0n1sa count=1 bs=4k of=/tmp/xxHow can I dump more than the 4k? I've tried many dd options but none seem to work.thanksmd

count=1, bs=4k => 1 * 4k = 4kIf you want more data, you need to either enlarge the block size, or don't tell it to stop after one block.-- Darren
