Any time I've seen this problem pursued (as opposed to throwing up
hands and just using partitions) it was found to be the motherboard
(well, the UEFI bit) deciding that a storage device with no GPT or
MBR needs an empty GPT adding to it. This corrupts md arrays on whole
devices.

Example:

Is it possible that this is happening to you?

If not, once again I urge you to go on over to linux-raid list and
describe what's happening.

Cheers,
Andy
