I wanted to post a follow up on an apparent problem with external disks. As a quick review I have a Mac 2 running A/UX on an internal 80Mb drive with 3 80Mb external disks. I have run several tests and have come up with the follow observations. When running a disk intensive program in the background and light disk activity in the foreground the system will hang on some kind of disk access collision. I have scanned the disks for bad blocks and found nothing. I have written several programs that cause heavy disk activity but only one disk at a time. As far as I can tell the problem only happens in the above cause. My guess since I don't have driver code or test equipment, This could be similar to the SUN connect/disconnect hardware bug in the early 3/50's. Any comments are welcome and please do so. I would like to work this out if it is possible.
