I have DVD burner Pioneer DVR-112D failing on FreeBSD-9.1 amd64. It begins to write ok, but later gets stuck at some percentage point with "the LUN appears to be stuck" message (log is below). Command used to burn is: $ growisofs -dvd-compat -speed=4 -Z /dev/acd0=my.iso growisofs is from dvd+rw-tools-7.1, which hasn't been updated from 2008. cd0: <PIONEER DVD-RW DVR-112D 1.21> Removable CD-ROM SCSI-0 device Now there is a dilemma. Does this mean that the burner went bad? Or does this mean that there is some fault in the burner driver? I know that few years ago this burner worked fine on BSD. Maybe anybody has an expertise and would know if this error means the hardware or software failure? Anybody is able to burn DVDs with the same/similar burner? Or maybe some other command should be used for burning? (growisofs is recommended by the handbook) Googling the message doesn't clarify the issue.
