I have recorded about 30 hours on my C: drive without a single problem. Yesterday I went out and bought a new hard drive which I could dedicate entirely to captured video. It is a WD 120GB internal, 8mb cache and 7200 rpm. Both hard drives are on the same cable and both are set to Ultra DMA. However, when I begin recording it instantly starts dropping frames and the video has visible slowdowns and sometimes freezes completely. Obviously it is not anything that may be running as when I switch to C: it works perfectly. Any suggestions? Thanks!
