I am having the same difficulty. I purchased this brand new drive off ebay. It's actually showing up as a Sony DW-D26A on my computer. From what I've been reading they are the same drives. I've tried to speak with Sony about the problem and they offer no support for OEM products.
So, I now have to figure out how to get my computer reading this as the LiteOn drive and not a Sony right?
So, my drive is acting the same as PAKman's is. I have it set as Secondary Master after finding out it was unresponsive to being set as Secondary Slave. Not a big deal. however when I insert a CD or DVD regardless what type the drive doesn't show me the files.
I'll try to answer C0deKing's questions as best as possible for my drive...
The green light comes on for about 10 seconds. It's solid and does not blink.
Autoplay does not work even though it's enabled. The drive retitles itself when I look in My Computer from "DVD-RW Drive (E:)" when no disc is inserted to "CD Drive (E:)" when I have a CD inserted.
No unfortunately I do not have another system available to me to test it on.
Since this is a Sony OEM drive is there some sort of flashing utility to convert it over to the LiteOn supported one?
Feel free to PM me also.
