Your machine seems to be suffering genuine link layer problem. In
most cases, this indicates hardware problem and in my experience
common causes are (in the order of ballpark frequency)...

1. inadequate power supply

2. device and controller don't like each other on 3Gbps

3. cable too long or flaky connector (especially w/ eSATA cables or
genders or backplanes)

4. faulty controller or drive
