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):
Steps to Reproduce:
1. As root: /sbin/hdparm /dev/cdrom
2. Returns: /dev/cdrom: Permission denied
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
closing based on last comment. This looks more like a udev problem anyway. (udev
creates the device files in /dev)
