The same lines go for ata6 and ata5. So 3 drives have bad cables? I
have to mention before starting the reshaping process, I did not see
these errors or at least they were not as pronounced as they are
today.
I'd have a close look at your power supply rather than the cables.
I've seen odd behaviour across multiple drives when they were all under load (as they are in a
reshape) which went away when I replaced the marginal power supply with something more substantial
and better engineered.

Brad
