SE-S084C and SE-S084D are different drives, in fact they are very different in just about all respects, probably due to SE-S084D's extra ability to behave like a hard disk when connected to a TV/device with an integrated media player.
MCSE doesn't support it yet. The firmware seems to be quite different from the normal SE-S084x firmwares. Its only 1MB in size rather than 2MB as all the others, which suggests that parts of it might be compressed/encrypted.
Better ask ala42 to see if he can add support for it in MCSE ...
