can't access cd-rw after switch to ide-scsi
I'm having an access permission problem with my cd-rw drive. I switched it to ide-scsi (added hdc=ide-scsi to boot parameters) and now I can write to the drive with cdrecord, but only as root. Similarly, I can only rip tracks from the drive as root. I can mount data cd's and read them as a regular user (configured user in fstab). Before I switched to ide-scsi, I could rip cd's just fine as a regular user with group cdrom premissions. /dev/scd0 has read/write permissions for group cdrom, but still I can only use grip, cdrecord as root. Anyone know how to fix this? Thnx. Cheers, Tim P.S. Hmmm... just noticed that all /dev/sg* devices have only root permissions... should I chgrp them to disk and add group rw permissions? Create a scsi group? T. -- Timothy H. Keitt Department of Ecology and Evolution State University of New York at Stony Brook Phone: 631-632-1101, FAX: 631-632-7626 http://life.bio.sunysb.edu/ee/keitt/

Setting '/dev/sg2' to group 'cdrom' + 'chmod g+rw' did the trick. Thanks. Tim Carel Fellinger wrote: On Fri, Jan 26, 2001 at 10:47:57AM -0500, Timothy H.
