Sorry about the long subject line and I hope this is the right place for the thread. So here's my problem: 1. I have a 250gb Seagate Barracuda 7200.9 Ultra-ATA in a Lacie D2 enclosure. 2. When I go to format it, it's capped at 128gb. 3. I'm connecting through Firewire on a Macbook Pro running 10.5.5. I thought a firmware update might be the issue at first, but I couldn't find any such thing on Seagate's site (which said that my drive under Mac OS X shouldn't have this problem). I've Googled around and seen a lot of brief mentions of adding/replacing kext files in System/Library/Extensions, but nothing seems to necessarily fit my case. I tried installing AppleVIAATA.kext based on one thread, but another thread suggested that wasn't right for an Intel Mac. I'm open to the possibility that there's some incompatibility between the drive and the case, but I feel like that's a stretch (since it works at all) and I'm hoping that's the least likely scenario. Thanks in advance for any help you can provide.
