I bet you're erroneously using the buffered devices, where you should use the raw ones, are you? This vastly increases the source of possible problems, by including the entire buffer cache into suspicion. Well, uhm, no. I have been using /dev/rfd0.1440 (9,3)... either with tar or with mcopy. But answering your question caused me to discover another thing. It only seems to fail when it is copying data to/from the wd0 device. I just did several copies from sd0 and /tmp (mfs), and no problems. The CPU is a IWILL P55TV with integrated fd and wd. Should i perhaps move the wd drive to the OTHER onboard controller? I assume FreeBSD would not freak over that... -mark p.s.
