Okay well this is nothing to do with your RAID, it's at a much lower
level.
I'd suspect a faulty drive if it wasn't for the fact that you say it
doesn't happen if you boot from power off, only from a reboot.
I think it still might be worth changing the cable and/or moving the
drive about to see if the error follows the drive or stays with the
port.
Do you have multiple of this model of drive? If so then it would be
interesting that it only happens with one of them - again points to
hardware problem. But if you only have the one then you can't tell
that.

Hopefully that model number and serial gives you enough information
to locate the correct drive.
