Hey guys, I'm looking into an external HD to back up my iMac data after some files got corrupted and I lost a lot of important stuff and had to reinstall the OS. Anyway, it's an iMac G5, and I need something around 400 or 500 GBs. I've looked into a few and it looks like LaCie and Seagate have reliability issues with their external HDs (I have a Seagate internal and love it, but not so for externals?), and I've been looking into Western Digital and Iomega. Any recommendations? Personal preferences? Things to avoid?
