I have changed SATA cables twice and I added a better PSU. The problem
persists.

Do you have any insight on the sectors count mismatch I mentioned in the
first mail?
The disk is 250GB but it looks it is searching for a 500GB disk (that is
md0 = sda + sdb).

Is it possible the SATA reset thing to trigger an md bug. I am totally
