Sure. The drive is faulty. If you are in the UK and had it less than six month then the itme is assumed faulty and should be replaced or refunded. Unless the SHOP CAN PROVE it was not faulty at time of sale. i.e. to they would have to prove you broke it, e.g. signs that it was dropped or misused. Obviously a drive tray is expected to eject for at least a year without breaking.
If it has been more than six months the onus is on YOU to prove it was faulty at time of sale.
So be quick!
