well i've also dl some anime and music to my secondary harddrive, which windows xp still recognizes, but the playback is choppy for some reason. so i cut and paste the files to the primary harddrive, and playback is fine.
i use dvd decrypter and nero. when i use the primary hard drive it takes only about 13 minutes to rip a dvd with my pioneer 110d, read speed was up to 11x (to rip to the secondary hard drive it takes 1hr and read speed is only about 1.1x tops with the same hardware). it takes 15 minutes to recode and burn from the primary at 8x, and it was taking 1hr and 20min to recode and burn from the secondary with the same config.
so am i safe to say that something is wrong with the secondary harddrive? that it's unusable?
