An optical drive provides more rapid writes to an optical medium by analyzing defects detected on the optical medium to predict defect areas and avoid writes to the predicted defect areas until the defects are confirmed or refuted. For instance, a defect detector analyzes for a predicted defect if two or more substantially adjacent blocks of the optical medium are determined as defective by associating the determined defectives with a defect shape, such as a scratch, a fingerprint or a spot. The predicted defect is an area of the optical medium extended in the form of the shape in the direction of subsequent writes. The predicted defects are confirmed or refuted with test writes during an idle time, such as after completion of the write or in batches that make updates to a defect table more efficient.
