I have a Power Mac dual G5 in which I recently installed a PCI-X eSATA card from EZQuest (ezq.com). I also have a Seagate Freeagent eSATA hard drive (750GB, with USB/FireWire400) that I connected using an eSATA-eSATA cable to the computer. The drivers that came with the EZQ card are installed and am able to see the PCI-X card listed in the System Profiler (I couldn't see the card before the driver was installed). However, I do not see the Seagate hard drive anytime I connect it (tried booting and then connecting, connecting and then booting) - it's not even seen through Disk Utility (I guessed that it may require manual mounting for some reason and went to Disk Utility to confirm if it was even detected). The hard drive works fine on USB or FireWire 400. Questions: 1. What exactly is required to configure a PCI-X eSATA card on the PM G5? 2. If it's configured correctly, would I see this card under SATA devices as well (apart from the PCI-X devices)? 3. Is there an easy way to find out where the issue is? I do not have another computer where I can stick the PCI-X card. I do not have another eSATA hard drive either. I'm used to working with Unix commands, Terminal, etc. - so any geeky things I can try are also welcome. Any suggestions or help would be appreciated. If anyone here has configured and used eSATA on a PM G5, please do let me know what exactly I should look at (and if I've missed something). Thanks!
