So, once again I forgot to add the funny-markers... On a serious note, if I remember correctly drbd saves its "this is a drbd-device" information at the end of the partition (if at all), so when you plug the disk into a different machine and just want to access the data, its the same as with md (with metadata=0.99): Just mount the partition.
