Hi Vez,
maybe there´s a problem with the IDE-to-SATA adaptor, some of them seem to cause problems.
Please ask AJ for that, as far as I knwo he helped a few others with similar problems.
After AJs SSD Upgrade I had as well a few reading errors, so I removed his adaptor and replaced it with my old one ( I had a SSD installed already

). Now it works without harddisk-problems
