I got those errors when my card was inserted on wrong PCI-X. Not your case.
I goes you are using a firewire or usb audio card. are you using an internal firewire/usb port or an adapter (PCI-X to Firewire/usb, or something else) ? Did you had some other device installed on that port?
Try to use the port that is onboard, on the mainboard, not with a bracket...

If you're trying to do this with a single hard drive (you stated A-as in one-terabyte hard drive) you're just asking for all kinds of errors. You need a dedicated secondary hard drive. From the MAC troubleshooting page:
IMPORTANT! You MUST use a secondary hard drive (not your main OS drive) for recording and playback of audio in Pro Tools. Recording or playback from the OS drive is known to be problematic and the cause of many different error types. If you are using your system drive and encountering errors, the first thing you should do is get a compatible drive.

Pro Tools supports recording and playback to a secondary drive that meets the following requirements:

7200 rpm or faster
9ms seek time or faster

Please note that this has nothing to do with how LARGE the drive is. You STILL need a secondary drive if you want this to work correctly.
