Well, its clearly getting I/O errors trying to access the drive. That could point to several possibilities:
* Bad SATA port. Try connecting the cable to a different SATA port on the mobo * Bad drive. But you already changed the drive out, so maybe not a bad drive. * Bad power supply. The power supply could be going wonky and causing the drive to reset. * Bad SATA cable. Sometimes old SATA cables can't handle the higher bandwidths of newer motherboards and drives. I have piles of cables at home and over the last 10 years I have had to throw half of them away because they could only handle SATA I or SATA II speeds. -Matt
