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
