Happy Holidays to all: I know this has been covered extensively in the past, so it might be best to reply directly to me off the list. I am about to replace my HD ( a 30GB Quantum fireball) with a new Seagate 80GB (I lust for silence) 1)do I want cable select or master? 2)I have a OWC mercury FW enclosure for the old drive. Any pearls there? 3) I want to upgrade to Jaguar from 10.1.5 I am totally confused about whether or not to partion the drive or not? I am a home user. 4) I want to put my extensive music library on it for use with my iPod and I also have a pretty big iPhoto library. How should I best do this with my new (old) FW Drive? 5) My kids have a older iMacDV that I would like to airport so they can look up their e-mail on their computer. Do I still need the airport station now? And how many airport cards? Happy Holidays. Thanks for the help, Mark mplunkett at austin.rr.com
