This problem im having is very often.
i got the pioneer 109 oem with 1.17 firm
yesterday i tried to burn 2 riteks g05, i inserted the dvds and 2 programs nero and recordnow were unable to detect the blanks, they said there was no dvd in the drive, so i tried another brand of blank dvds, and same problem, both programs said there was no dvd in the drive.
So, i rebooted the pc and miracle, after that recordnow and nero detected the blank dvd inside the drive..
Wtf is going on?
i got this same problem sometimes when i insert a BURNED DVD WITH DATA inside on the pioneer 109, the drive starts to spin the dvd for a couple of seconds and windows does not detect the dvd, ( inside My Computer icon the dvd drive icon appears but doesnt detect the dvd and there is no VOLUME LABEL like for example gcmospeadadvd1 volume label.
sometimes if i right click on the dvd drive icon, the drive starts to spin again and then it reads the dvd, detects the volume label and the data inside.
doods this 109 drive has serious issues.
