Not really.

I have had bit-errors in RAMs that memtest86+ did not find.
I had to run an unserspace memterster under Linux....

Can you determine the exact nature of the corruption, i.e. can
you compare a corrupted file with an uncorrupted version?

First, SATA uses checksums ion all transfers, uncaught corruption
is extremely unlikely.
The suspects are:
- RAM (memtest86+ seems npt to do a good job anymore today, unfortunately)
- CPU (bus/cache)
- System bus
- Chipset, especially SATA controller
Since you have corruption only on one port, I would say the most
likely candidate (almost certain) is the SATA controller. All other
candidates should cause corruption on the other disks as well. It is
possible thet the SATA controller causes some corruption on its 3rd
port internally, before the data gets fitted with checksums.
Advice: RMA the board.
