It might be S.M.A.R.T reporting an error on the drive that was
remapped by the drive.  Take a look at
/usr/ports/sysutils/smartmontools.  You can read the smart info off
the disk to see if the amount of bad sectors are increasing or not

Try
smartctl -a -d 3ware,1 /dev/twed0

If you install the daemon, it can monitor changes for you with more
detail

e.g.


# smartctl -a -d 3ware,0 /dev/twed1
