I don't think that's possible. If your disk gets corrupted, it may write bad data, true. However, DRBD doesn't re-read the written data from disk before replicating. The DRBD driver replicates whatever your local kernel *wants* your disk to write. Corruption of your replica can happen if 1. your link is faulty and the transmitted data is altered or 2. the drive in your Secondary becomes corrupted There may be other scenarios.
