Your system does not seem to hangup.
So, this is rather good. But this makes problem difficult to solve.
When the sector on wd0 is broken, the last two error messages will
appear in /var/log/messages.
So, If you can check the secter is really broken or not,
it will help solve this problem, for example, check the disk
by windows scandisk or norton utilities, or write to all of vacant
disk area and read all file.
They say that the recent eide disks are implemented the automatic remapping
function, in this case, so even if the sectors are actually broken,
they are substituted, no bad secters may be found.
If you cannot access that disk after the error message,
probably, wd driver does no work well.
So, check /usr/src/sys/i386/isa/wd.c,
and find out the lines such as
du->dk_timeout = 1 + 3;
and increase the value.
There are several views that the failure of disk is cause by
the heat or the unstable power supply.
