(windows PC) A few weeks ago, any audio streaming to/from my dedicated audio drive (160G maxtor) began stuttering. It would basically dropout any time the disk was accessed - so, in playing back a file, the disk light would flash say once a second as Windows read the data. Each time it flashed, the audio would hiccup. I tried increasing the read buffer size in Sonar, but all that did was make it so that there was a longer time interval between hiccups, but when they happened it was much worse. So, it is not that the disk access isn't fast enough -- it is that it is interfering with the audio stream. As a test, I moved the audio files for one project to my primary HD (80G maxtor). The stuttering stopped! Both drives are SATA-150, hooked up to the SATA jack on the motherboard. The audio drive is nearly empty, and has been defragmented. The one thing I know changed around the time this started happening was that I upgraded my video card (from a 9600 to an x800). But I'm not sure why that would affect only one drive. Anyone have any ideas?
