Corrected entry: When Frank Poole and HAL are playing chess, HAL states his move as (in what is called "Descriptive Notation") "Queen to Bishop Three". This is not true, the move he makes is "Queen to Bishop Six".

Correction: This mistake is intentional, meant for the astute viewer to notice that something isn't quite right with HAL.

Corrected entry: When Bowman leaves Discovery to retrieve the AE-35 Unit, he asks HAL to prepare the "B Pod" and HAL powers up and rotates the middle of three pods. Later, when Bowman asks Poole to help him with a problematic transmitter in "C-pod", they go to the pod bay and enter the middle pod which must still be B-pod as no two pods have left the ship and returned to shuffle their positions.

Correction: This could be a character mistake. And it makes sense in the context of the film. It's the exact kind of thing that would make HAL paranoid if Dave and Frank entered a different pod that they mentioned earlier. It's kind of a counterpart to HAL incorrectly identifying the sequence of moves to checkmate in the Chess game he was playing with Frank.
