Bug 86206 – cdrdao gives error when trying to burn as normal user

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description NightTwix 2005-03-21 18:53:13 UTC]

burning as root is working and setting SUID on cdrdao works as well (thats the solution/workaround mentioned in the forums).
But i just cannot imagine that this is the correct way.
btw, cdrecord works fine after i added the user to the "disk" group
so, its only cdrdao giving that error when trying to burn as non-root...

Reproducible: Always
Steps to Reproduce:
1.cdrdao write --device ATAPI:0,1,0 some.cue
2.
3.

Actual Results:

Can you try with cdrdao --dev=/dev/hdc (or whatever your cd-recorder is)?

[Comment 2 NightTwix 2005-04-20 14:21:33 UTC]

it's working with "--device /dev/hdb" and SUID bit NOT set.
but i can't test if it's working now with "--device ATAPI:0,1,0", too (cause i just used my last empty cd ;)

> it's working with "--device /dev/hdb" and SUID bit NOT set.

The the proper way for access to the drive.  As it works, I close this bug.
