I installed cdrecord on FreeBSD 6.2. Result: cdrecord dev=/dev/acd0 -data 6.2-RELEASE-amd64-disc1.iso cdrecord: No write mode specified. cdrecord: Asuming -tao mode. cdrecord: Future versions of cdrecord may have different drive dependent defaults. cdrecord: Continuing in 5 seconds... Cdrecord-Clone 2.01 (amd64-unknown-freebsd6.2) Copyright (C) 1995-2004 J on this OS. Cannot open SCSI driver. Then I installed cdrecord on NetBSD 3.0.1. It happily burned 6.2-RELEASE-amd64-disc1.iso and 6.2-RELEASE-amd64-disc2.iso. NetBSD will mount both. FreeBSD 6.2 will mount both. So: There is something different on a CD burned by cdrecord and a CD burned by burncd. There is something different between FreeBSD mounting a CD containing an ISO and NetBSD mounting the same CD.
