The drives were purchased from a wide enough variety of sources and at different times, so as to preclude the possibility that we were burned by one bad manufacturing run. I guess that is what Quantum gets for pushing the envelope. I was suspicious that Quantum's drives had quite a bit faster seek times than other drives in a similar price bracket. As maligned as Seagate drives are, we've had only a few failures out of several hundred ST 225, 238 and 251-xx drives in use. Out of just a handful of Quantums we've had about 1/2 of them go bad. The problem with the Quantums seems to be 'stiction'. It looks like the heads stick to the platter when the drive spins down, and thus prevents the actuator from getting out of the park position when power is re-applied. Seagate has had some stiction problems, as well as have other manufacturers. It looks like everybody but Quantum figured out how to fix the bug. Bill
