Plextor - cdrecord: Operation not permitted. Cannot send SCSI cmd via ioctl
Last modified: 2008-05-06 11:58:38 EDT
Description of problem:
When trying to burn a CD as a regular user on my external drive (Plextor
USB/Firewire drive), cdrecord fails and errors out:
"cdrecord: Operation not permitted. Cannot send SCSI cmd via ioctl"
- As root, no problem. Everything goes fine.
- I don't run into this problem with my internal cdwriter (at least with
cdrecord). Everything is fine with it, even for a regular user.
- that happens whatever the action (blank, write) or the argument -dev=/dev/scd0
This bug reminds me of the bug I'm still running into with cdrdao.
Version-Release number of selected component (if applicable):
Cdrecord-Clone 2.01.01a03-dvd (I didn't test with other version)
Steps to Reproduce:
Problem with Plextor ioctl commands.
Is it fixable ?
yes in the kernel... you may also try the "driver=generic-mmc" option.
I think this bug is a duplicate of bug #179862.
