The BSD partition was created larger than the actual available blocks, thus whenever the OS sent data to blocks that didn't exist, you got this problem. If this is setup OK then as the other poster said your days on this drive are coming to an end. IDE drives have a number of reserved blocks available that are used internally by the drive to map out bad sectors. When a drive starts going bad the sectors start failing one by one and the drive maps them out - when it uses up all the reserved blocks then the drive starts returning errors to the operating system. If this drive supports S.M.A.R.T. and it's enabled and your running 5.X then smartmon might give you some data about the actual real state of the drive, rather than the lies that the drive normally tells the OS.
