No worries.

If the second hard disk is internal then I wouldn't have thought that the fact your music is stored on this drive instead of the primary drive is going to be causing a problem. However, just to eliminate that possibility completely, you could try copying a couple of music files over to the C drive and then playing them from there just to see if it does make any difference.

I meant to ask you before - do you still have that processor to memory IO Interface error in device manager?

Also, what is the DMA buffer size set to in the hardware settings for the Edirol and which driver are you using? (ASIO, WDM, EASI or MME)

Apart from that, I'm going to ask you to do a few little experiments for me....
I want you to try playing a few different audio formats and from a variety of locations using different applications.
e.g playing:
streamed audio over the internet
normal audio CDs
wav or wma files that are on your hard disk
mp3 files that are on your hard disk

Try each of these using as many different players as you can. e.g Windows Media Player, Windows built in CD Player (in Program file -> Accessories -> CD Player), iTunes, any other audio applications that you may have. In particular, try and play some of the music files which you have been listening to in iTunes by using a different application and see if the distortion is just as bad.

Make a note each time of what the sound quality is like. I'm trying to ascertain whether there's any significant pattern to this. You also mentioned about cpu spikes in iTunes - keep an eye the cpu usage to see if similar spikes are also occuring in other applications.
