I'm dealing with one now that seems to have some unexplainable anomalies. It's clearly using a single sector stripe size, I've confirmed that several ways including by using entropy analysis (and experience told me to expect this). However, I've built the RAID every possible way and none of them are correct. I've confirmed that the XOR is good from beginning to end across all three drives, so it's not a matter of an out of sync drive or anything like that either. An offset shouldn't make any difference with single-sector stripe size, so that's not really a concern.
So the only possibilities are that it's some sort of non-standard block rotation or a parity delay. Any ideas?
