Welcome to how Sun and IBM walks its way in to most shops and why FreeBSD never gets a chance. I have heard it Sooo many times before. I want someone I can blame and point to. (are you a manager by chance?) If that is how you always operate do you only use FreeBSD when they won't go for your 'known working solution' you can point fingers with? > At this point, without good technical data of what/how the harddrives were > handled, the power supply, the quality of the AC line, etc la, this thread > is generating heat to keep one warm, but not alot of information.

OR, the hard > drive was abuse by a shipper. OR...... Yes however I will bet even money that if I put a seperate power supply on every friggen drive and still have the same problem someones gonna say.. I bet one of Those supplys was bad.. Can folks try, just try to imagine that they "could" be wrong and come up with some other reason? Do I honestly have to Prove it wrong in some scientific way before you are willing to imagine some other possibility? Jeeze. Some time I or someone else will have a chance to test the theory, but for now that is all it is. One thoery. Did you read, really read, my last two posts on this? Nicole Ok Now I am getting a little snide. It just feels like what galileo went through.
