That a CD changer is not supported this way. Just today preliminary support for CD changers went into FreeBSD 3.0-current. 2.2.2R has not support for interfacing a CD changer as multiple standard CD. What the machine sees is a single drive and, if you're lucky, the changer mechanism. You may be able to use raw SCSI commands to activate the changer and mount/umount the disks manually, but other than that, or the new code in 3.0-current, CD changers are not supported, at least AFAIK. > How can I fix this ? > > Any idea is welcome. > > Mira > > -- > ----------------------------------------------------------- > | Miroslav Kes | > |---------------------------------------------------------| > | Rockwell Automation Ltd. | tel.: (+420) 2 2425 6913 | > | Research Center Prague | fax: (+420) 2 250467 | > | Americka 22 | e-mail: mira@rockwell.cz | > | 120 00 Praha 2 - Vinohrady | | > | Czech Republic | | > ----------------------------------------------------------- Nadav
