If it has a C1 next to it you can bet it is a capacitor.
You should have rows of them on the card.

Is it is the one by the resistor and transistor?
Or the one by the two 'normal' looking capacitors on the other side?

There are way too many of them to be zener diodes.
And you should be able to pick out the 1N914 diodes.

It must be a cap as it did not affect the drive that much.
