With the CD on HDD, I could read off of HDA just peachy while the system was choking on a scratched (aol) cd. I did a WC of a 300MB file (only 256MB of ram on the system, so that's guaranteed to not fit in any cache). Times to read the file were statistically equivalent whether the system was choking on the CD or not. -- Stephen Samuel +1(604)876-0426 samuel@bcgreen.com http://www.bcgreen.com/~samuel/ Powerful committed communication, reaching through fear, uncertainty and doubt to touch the jewel within each person and bring it to life.
