Hi Tony Just to mention, it's worth taking a look to see if the shield on the back of the optical drive carrier is properly slided on and not popped off like mine was which sounded like a fairground attraction till I checked it found it hanging flappily and put it on properly. I mentioned it to the shop who said it was perfectly normal for one of those to have come off due to transit, ie driving home from shop. I didn't believe them and since then it has not come off when being transported under the same conditions as the day I purchased it. All shops are prone to these little niggly half truthes it seems.
