Every Maxtor drive ever made has a unique serial number, and the ones people are seeing are completely invalid. This issue should be root caused, something is getting stomped on, and it may affect more than just the ID of the drive. I fear that these are bandaids covering some underlying issue. --eric On Thu, 2 Dec 2004 09:27:20 -0500 (EST), Justin Piszcz wrote: > The interesting part of all of this is that this only occurs when I have > the two cdroms on a promise controller, on the same IDE channel, normally > I have them both on the motherboard as master and slave.
