Damn! This is terrible news. Thanks for the reply -- I really appreciate it and I can identify with the "pure hell" part, grrrr.... :-) I have swapped entire Sun Blades, I have swapped disk drives (twice) and no joy. :-( All the Sun Blades we have here have Western Digital 40 GB IDE drives in them. We only have Western Digital 40 GB IDE as spares, obviously, duh... I will have to see about getting an IBM IC35L040AVVN07 drive, sigh... Thanks again. (this is such a pain...)
