IIRC all garbage you write to DRBD gets synchronised. Data getting corrupted at the hardware-Level (e.g. Defective Raid controller) only gets synced if you trigger a resync after you did a online verify and found out the data differs. DRBD has no way of knowing what goes on on the hardware underneath unless it is notified by the Kernel via an IO error. Same goes for modifications of the data when drbd is not running (writing some garbage to the partition with drbd stopped - there was some discussion about exactly that scenario in the past).
