Ok, so apologies if this has been covered before (couldn't find it in the searches), but I've just read an interesting piece in Mac Format UK discussing the woes of the first Rev D Alu PB Superdrives. Apparently, the original '8x' Superdrives in these PBs' are Matshita 845E models that cannot run at 8x despite Apple's claims and in fact, only run at about 2-3x for most, if not all, of a DVD burn. The Apple blurb states that this drive can burn 'up to 8x' but few have ever reported this to be the case. The guy answering also says that this model of the superdrive has been dropped in favour of a newer 845 model that still cannot run at 8x. Not knowing how to monitor burn speeds, I'm not really sure what my (845E) version has been doing it at, but I know I seem to wait a lot longer for stuff on the PB. Anyone got a newish (last couple of months) PB they could check their model number on? Edit: Lesson 1 - read something properly... I've just re-read the letter and it seems the problematic drives are actually Matshita 835 models which were dropped in May for the the 845 version. So this PB has the newer drive but it's still slower compared to the pioneer one at work.
