Tried cdrecord dev=1,0,0 -data (it is on bus 1) but I get the same error message. Also, tried setting the permissions on acd* cd* xpt* pass* devices in /dev. No change. I really get this feeling the OS thinks it is a read-only drive. When FreeBSD is installed, it gets some information from the BIOS. Lots of important stuff like the geometry of your hard drive, etc. If the BIOS is reporting this wrong or not the same way FreeBSD see a device, things can break. Is there a flag somewhere I can flip so that the OS know it can write to this device (the DVD-RW)?
