I HAVE searched, really!
This is the drive id given by XP on an ACER Aspire.
The machine was bought by a friend as including a CD RW and DVD RW.
It reads and writes CD’s ok.
There is even a DVD Burn program came on the box.
It will not even recognise a DVD disk.
To my simple mind it probably is not even a DVD reader!
The box has been sealed with a no tamper warning so I can’t even open it to check further physically.
