Again this is a topic of religion. This means that the bus interface doesn't make the drive a good drive. On the other hand, there are so many verions of BM drivers that are crap thus forcing the user to use PIO drivers. A number of ripper programs out there will display a CRC value at the end of the track. CRCs are a method of applying a mathematical formula to a block of data to give a resulting value which is very likely different if even a tiny piece of that block of data changes the next time the CRC is calculated.
Many people find their resulting wav file suffers from a change in pitch.
Apart from the problems of a system that isn't generating a proper clock for playback, there can be a couple of reasons that the wav file itself could be at fault. If the drive is suffering from frame slip, or sample slip, the overall wav file will end up containing either fewer or more samples than it was supposed to and this will cause a change in pitch. It will also likely introduce pops and clicks. We did a simple and unscientific experiment. What we found was that it IS possible to make a perfect copy of a track as far as the bits go.
