WebTo verify the readback data stream, compare it to the RBD golden readback file and masking readback bits with the MSD file. This approach is simple because there is a 1:1 correspondence between the start of the readback data stream and the start of the RBD and MSD files, making the task of aligning readback, mask, and expected data easier.
