But then it is hardware and back to the above explanation. I doubt that a SCSI bus reset can make an optical drive open (allthough it can close an open one); ATAPICAM facility, I think, can't do something similar. I would really think it may be a hardware problem, sparks on the SCSI line (or whatever kind of bus the drive uses). :-) >From my own experience: I have a CD drive (old, 16x) that tends to close automatically when opened, but just sometimes, sometimes not. It even does this if connected to power only, so there are no "controlling informations" transfered into the drive's logic. Commands like "camcontrol eject" can be used to intendedly open an optical drive, but most settings require certain user permissions (on the controlling devices) to do so, and I don't think programs like the ones you mentioned to have such abilities... -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
