Indeed - Hoewver, consider the situation with (say) 6 or 8 drives in a CCD as a news spool - if one drive develops a hardware fault then (until we get some sort of redundancy support) you are going to lose the entire ccd anyway! I guess it all depends on what you think will break first - a drive (and you are now N times more likely to lose one) or the OS, power source, etc. In my experince of running half a dozen news servers in the past 2 years, it's always been the drives that have failed )-: Gordon
