  1. Make sure you aren't using an HD (1.44 MB) disk (which has the density select hole where the 400K disk sensor is, so it will never appear to be inserted).

Your disk should have only one hole along the outer edge, at the left (with a slider for write protect), ie. 400/360K (single sided, double density) or 800/720K (double sided, double density).

For testing purposes, you could cover the extra HD hole with tape, but it may not read/write/retain-data properly.

Otherwise, I would guess:

2) you have more dried grease to remove to allow full travel of the mechanism


3) the eject motor is stuck at a partially ejected position, preventing the mechanism from allowing the disk to seat fully.

HTH, James
