ND3540-A - removed features?

After flashing my ND-3540A Liggy’s 104bt_rpc1 (previous: 101d_rpc1), Scan Disk in Nero CD-DVD-Speed always seems to report all disks as 100% green and ok, even those that I know not to be. In the description of the 103bt_rpc1 firmware, there was a hint that some features had to be removed. Is this also true for 104, and might that be the reason for the unexpected behaviour? How about 1W9?

In the 1.03 firmwares, some write strategies for specific discs had to be removed. But that doesn’t seem to be the case for 1.04.
