Heh, cool. Just FYI, I tested my changes using a rebuilt version of dd from 5.90 and it behaved fine using `iflags=direct' and `oflags=direct'. If you notice any problems, though, kick me immediately. Just keep the alignment restriction in mind. MSDN says that it's not necessarily enforced, depending on the device, but dd should obviously take this into account.
