When this drive arrived it was the wrong item (they sent a Combo drive) and it did not read any disks at all CD or DVD. I contacted computer trading and they sent the correct item this time, however it too would not read any disk reliably and failed to write to any type of disk either. On top of that it made a loud scraping noise when the disk was spinning. By this time I had decided not to proceed further with this company and opened the drive to effect repair myself if possible (don't do this if you don't want to lose your warranty). On opening the case I found that the drive was a repaired drive unit and the labels had been rubbed off with some kind of abrasive material,so that they couldn't be identified. I managed to repair the drive and it now works reasonably well. I suggest that you should beware of any product you buy from 'Computer Trading' as they must be aware of the products that they are selling are previously repaired (and not that well repaired either) items.
