That’s a BenQ/LiteOn drive case design, so it must be a LiteOn…I think. I may be going crazy. Let me check.
EDIT: On second thought, it looks like a Samsung? Especially by the way the label is laid out; it clearly reminds me of a Samsung. And the indentions on the bottom of the drive scream Samsung.
EDIT 2: It looks like a hybrid BenQ/Samsung drive case design. The bottom and the label are all Samsung, the top ducts sorta favor BenQ, but some other indentions on the top look like Samsung.
The drive is made in Indonesia, from where Samsung drives come. I do not think that any LiteOn drives come from there.
I’d still say it’s a Samsung.
EDIT 3: I notice the new 22x Samsung has a case design like this, so it is a Samsung.
The emergency eject hole and eject button are in the same place as a Samsung, but the LED appears to be in the position of a normal LiteOn. It seems there was some customization for this drive.
Can you try to burn a DVD with the drive using CD-DVD Speed, and show us how the write graph looks?
