YET Kingston sold a SCSI III box with ONE SCSI cable 2.5 meters long. (Hint: 6 per 1.5 meter chain is pushing a non LVD SCSI III. Got to learn that the hard way) No way in hell what I was sold was going to work. Reminder 1#: Unless you know actual non-sales people who have a version of what you are thinking of running, or you have run it in the past, best to go with the idea NONE of it will work. That way, you don't wear egg on your face, AND you look good when it does work. Hard to quote jobs with that attitude, but under promise and over-deliver is always a good MO. > "It works for others." Yes...same argument used for the Kingston tower AND the Quantum drives. Turns out the Quantums were vers 4 of the EEPROM and its broke. To REALLY figure out what is going on, you need REAL data. Your employer won't pay for you to play Qualtiy Control Engineer. That brings me to reminder #2: Always quote the 'known working solution' IE the high end solution where it is someone elses problem. That way, if they opt to choose the lower end solution, you have the out of 'You should have picked the higher end version if you wanted this to work'. Life is full of compermises. 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. For all any of us know *ONE* gate deep in the 3ware is dead, causing the problem. (Had a SCO PC involved with a building lighting hit. Any mulitport serial card at 330 would fail. Move the cards to antoher machine at 330, it would work. Move the card to 360, and it would start working. Somewhere, a gate was dead on that machine.....) OR, the hard drive was abuse by a shipper.
