My understanding is that the new format doesn't cause I/O errors, just
slower transfer rates if you format with disk clusters that aren't
aligned on 4K boundaries. I'm not aware of any "support" in the

In my experience, I/O errors have always been hardware problems
(usually a failing drive, but it could also be a faulty cable or
connector).
