No, that's an unfortunate omission from the manual. Drive belt has been mentioned, but it can also be something fishy with the power supply, e.g. not delivering enough voltage to the drive. In very rare cases it can also be the disk presence switch which is faulty. But before you start opening up too much - are you sure you are using the correct bay? On SAM Coupé drive 1 is in the left bay, while on SAM Elite drive 1 is in the right bay. Regards, -Frode
