Ok, swapping physical port connections with the 500GB and the 1st 37GB fixed that problem. I noticed that when I boot from DVD system-rescue, if I check the mounted FSs I noticed in the options rw, relatime, errors=continue, data=ordered. It's the 3rd and possibly the 4th that I'm questioning. Also, everything seems to be there ok. 

Now when I boot from the hard drive it goes through GRUB ok and starts initializing the kernel, but then it'll suddenly spit out the following:

"Unable to access resume device (/dev/sda2)"
"mount: could not find filesystem '/dev/root'"
"setuproot: moving /dev failed: No such file or directory"
"setuproot: error mounting /proc: No such file or directory"
"setuproot: error mounting /sys: No such file or directory"
"Mount failed for selinuxfs on /selinux: No such file or directory"
"Switch root: mount failed: No such file or directory"

I do have SELinux enabled, do you think that it may have something to do with that? I don't remember how to boot w/o selinux enabled to see. Also, is it possible that selinux just needs to rescan the drives? I seem to remember coming up with a similar problem back in Fedora 7 or 8, and I just booted disabling selinux and then doing a scan then rbooting and everything was fine after that. Any idea what the commands are/were?
