FreeBSD 4.x also works fine with these drives. I've installed 5.3,
experienced DMA errors, reinstalled exactly the same hardware with 4.10
and had error-free operation. The only OS that fails like this seems to
be FreeBSD 5.x.
These Maxtor drives may well be flaky, but they are very widely
available and frequently installed in commodity machines. As it stands,
you can't install 5.x on any such machine. Since hardware support in the
4.x branch is lagging, this means you can't use FreeBSD at all on a lot
of computers. Not good.
I'm amazed there hasn't been more noise about this.
