From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Galeon/1.3.21 Description of problem: hdparm (root) works fine for HD devices, but on /dev/hdd which is a DVD device, it only says: /dev/hdd: Permission denied I tried hdparm-6.1 which works fine as before. Version-Release number of selected component (if applicable): hdparm-5.9-1 How reproducible: Always Steps to Reproduce: 1. As root: /sbin/hdparm /dev/cdrom 2. Returns: /dev/cdrom: Permission denied Additional info:
what are the permissions of /dev/cdrom or if it is a link the device file it points at ?
Now it works again. After rebooting I couldn't reproduce the problem... But maybe there is a bug deeply hidden that only shows under certain unlikely circumstances.
closing based on last comment. This looks more like a udev problem anyway. (udev creates the device files in /dev)
