Hi all... This might be completely un-related... I have a box with 6 WD 80Gb BB series drives on a 3ware Escalade raid controller doing raid 5. Every now and then a drives seem to drop from the array for no reason. Its always a different drive, on a different port. Mabye the later WD drives have some issues. Perhaps overly aggressive timing? --Shaun Lanny Baron wrote: > Hi, > For what it's worth here is some info we rely on.
