>Description:
Before 8.1-RELEASE, on 8.0, I had some trouble to read the optical drive (like playing DVD, extracting music)

Not this is solved I can access my optical drive with mplayer, cdparanoia.

But I can't burn anything :

# burncd data downloads/gparted-live-0.6.2-2.iso fixate
burncd: ioctl(CDRIOCINITTRACK): Input/output error

dmesg says this :
acd0: FAILURE - MODE_SELECT_BIG timed out

atactl : 
ATA channel 3:
    Master: acd0 <hp DVDRAM GT20L/DC05> SATA revision 1.x
    Slave:       no device present



>How-To-Repeat:
Have an HP Probook 4510s.
