I have just put my computer in a new case with a different motherboard
Everything was working OK - except powerdown which I have not tested but may be now solved . . .
When I tried to burn a DVD-RW using burn2CD it told me to unmount using "drives"
Curious I thought DVD is not mounted . . .
Also I noticed that the CD/DVD symbol in MUT was appearing before the HD
Now both the HD and DVD recoder are set up from their own primary IDE connection cable on the motherboard
. . . m m m . . .
Nonetheless I opened the case and switched the IDE cables around (HD primary 1 - DVD primary 2)
I was then able to use Burn2CD
Maybe I am the bug . . .
Anyway thought best to report it . . .
