Problem: Mac HFS+ format can NOT handle drives 24 TB and larger without issue!
Solution: Use APFS for drives 24 TB and up.

I just found out about this.

TL/DR: Mac OS HFS+ format uses 32 bit addressing, and is not capable of error-free formatting of drives.

Apple's new APFS is 64 bit, so solves the issue.
