The driver hasn't changed much during the last years.
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...
