Just for clarification, "starts/stops" refer to completely powered down for several seconds - possibly even disconnected from power socket(s)? If the former is the case, I would start to (a) make a full backup of all data still on the RAID6 (b) afterwards, start to swap cables/positions/connectors where possible, note down waht you change and only change one piece at a time (c) as you get I/O errors right up front, are the disks seen by the system at all? I.e. can hdparm/smartctl still access them or are they more or less dead?
