A lot of the PC's and laptops I've seen switch component manufacturers seemingly at will. Two supposedly identical laptops may both have, say, an 8X DVD bruner. But it turns out one is from Toshiba and the other from LiteOn or some other manufacturer.
Don't know if that's the cause of your G5 troubles, but I assume Apple does component switching as well to get the best prices. Could be a light incompatibility between the two drives somehow. I've seen similar difficulties because users were't seating the disc firmly onto the spindle so the disc was ever so slighlty mis-aligned. The poor little drive motor couldn't spin it up to speed. But that was laptop drives -- a desktop drive doesn't have that little spindle issue to deal with. --- Rex. -----Original Message----- From: [EMAIL PROTECTED] [mailto:owner-macgroup at erdos.math.louisville.edu] On Behalf Of Dan Crutcher Sent: Saturday, February 11, 2006 4:01 PM To: macgroup at erdos.math.louisville.edu Subject: MacGroup: Reading DVDs I think I already know the answer to this question, but I'll ask it anyway: Does anyone know of any reason why a DVD I recently burned on my PowerBook (as a data backup disk, not a movie) can be read by all of the Macs I've tried it on except one: two eMacs, my PowerBook and a G5 tower can read it, but it can't be read by one other computer, a G5 tower that is identical to the other G5. I've checked system profiler to make sure that G5 has a SuperDrive, and it does. The G5 that can't read the DVD just spins it up for a little while -- based on the sound the drive makes, it doesn't sound like it's ever reaching the higher speed spin that is needed -- and then the tray pops out. No error message. Is this likely just a case of one drive being finicky? The DVD is a Memorex brand DVD-R. It seems like I'm running across more and more cases of one computer being able to read a CD or DVD that another, identical computer can't read. What's with that?
