Hi everyone. I'm thrilled to find a list devoted to the topic of G4 Tibooks! My name is Tim Clarke and I am a composer and sound designer for games. My dream is to have the "studio-in-a-box" and thanks to Tibooks this is pretty much a reality. I own and use the 667 Tibook which I bought about a year ago. I currently use Logic Audio, Peak, Recycle, Translator, Metasynth, I have one 18 gb Travelstar that I pack with me, but have noticed recently that under mac OS 9 the finder will not mount this volume, but it will under OS X (10.2.5)! I'd say this has been going on for over a week, and it coincides with some other firewire drive problems I've had on my desktop system (dual 450 G4). I often use the 18-gig Travelstar as a "removeable media" between the Tibook and the desktop, and I've used Diskwarrior a couple of times on this little drive in order to get it to mount. I'm also sorely dissappointed with the "5-hour" battery that lasts for more like 1-2 hours. What's up with that? Is there a 3rd-party battery, or some other solution to improve this? Finally, I'd love to replace the 30 gb internal drive with at least twice as much storage. Has anyone gone through that proceedure? Any recommendations? Are there any "multimedia" drives available in that size? I'm sorry if these questions have been addressed here before, but I'm new here... TC
