I've recently bought Lite-On 32x12x40 and NeroInfo Tools says that it is model LTR-32123S with firmware XS0K.
I've got a strange problem when installing for the first time this drive on WindowsXP.
When I open the drive pushing the button on the front panel, the tray closes immediately itself.
The drive was bought in 02'2002 in Germany if this helps.
Any ideas why the drive opens and closes itself.
P.S. Sorry for the awful english
