IT'S FIXED!!! YOU'RE NOT GONNA BELIEVE THIS!! award for the biggest tech-ahole definitely goes to me...
it was the sata power cable... i forgot that i had swapped my power supply a while back and left the power cable from the old power supply in and had been using it.. upon close inspection, sure enough, it was different..
i've been running my big file copy tests and all is working perfectly! hopefully there's still life left in those samsungs..
anywho, to all those who chipped in, thank you for your time and putting up with me!
