As far as my tests went, it does not matter where in the drive I write to with dd - it gets corrupted.
The example I gave was in order to simplify the description of what I was seeing.
Originally, The drive had a formatted partition and when I moved it to this USB/SATA enclosure I began experiencing those corruption errors. In one of my tests I wrote zeroes to a file on that drive and when I looked into that file there were these USBC blocks inside it too.
Of course after that the partition became so corrupt, I could not mount it any more...

My suspicion is that these USBC blocks are actually part of the driver commands to the USB controller to write the data and for some reason they are actually getting written to the drive.
