Hello, Alexander.

  No jumpers are set at all. I think, This dramatic is result of
"read-seek back-write" cycle, which works so bad on slow Green HDDS :(

  Really, I'm very disappointed -- in almost any "syntetic" tests
these green HDDs are FASTER than old Blue ones, but in this real-life
situation it is 7 times slower :(
