Summary: I trashed the original Samsung drive on my older Dell by manually closing the drawer with the computer off. There was no pinhole to manually open the drive. The Sony was very easy to install in the upper bay after loosening the securing screws in the lower drive.
Pros: It works smoothly, easily installed, very reasonable price.
Summary: Great for the price, strongly recommend. newegg is GREAT!
Pros: Installed perfectly, no issues fitting. Have used over a year and a half and cleaned the lens once so far and never had issues reading my DVD's or CD's. Direct copy to my DVD burner quick as well
Cons: flashing light is kinda bright at night...not really a con, just had to find something
