The disk and instructions that came with the SYBA PCI Serial ATA Host Controller Card said NOTHING about Macintosh and I have no idea how to install the drivers that must be required. Just a small question here - Did you try to use DiskUtility to find the new drive? It is possible that the new drive is not formatted as a Mac drive and won't show on the desk top until it is formatted. My $.02 worth - for what it's worth.
