I'm betting at least one of those has 4KB physical sectors and you
have a misaligned partition on it that is used by openSUSE and Ubuntu,
but not by Windows.

Misalignment is a configuration issue, not a malfunction.

So step 1 use hdparm to determine the physical sector sizes:

ie.
sudo /sbin/hdparm -I /dev/sda | head -25

should show the Sector sizes near the end of the output.

Once we know if any of your drives have 4KB sectors, we can proceed from there.

Here is the output:

option 2

WD Green drives are notorious for having a very aggressive power
saving mode that parks the heads right in the middle of doing work.

I have one Green but I use it for back-up which is not used.
