In-depth technology research: finding new ways to recover data, accessing firmware, writing programs, reading bits off the platter, recovering data from dust.

The 14TB WD Red Plus reports a speed of 5400rpm, but I believe it actually rotates at 7200 RPM.
The reason I suggested that you switch between Win XP compatibility mode and normal mode is so that we can locate the checksum byte(s). This will be necessary if we attempt to hack the firmware.
Can you also confirm the total number of sectors reported by the USB mass storage device? This will be slightly less than 14TB. These drives store a key sector in a hidden area at the end of the drive, or at least earlier My Books do.
If some 3rd party tools would allow to do the same like WD formatter does, then probably I would need just a regular USB bridge.
Meanwhile via HDD Sentinel I checked some info of the 14TB WD Red:
HDD capacity: 13351897 MB
Unformatted capacity: 13351936 MB
WWID: 5000CCA290C41C84
Nominal speed: 5400 RPM
Number of sectors: 3418095616
Bytes per sector: 4096 [Advanced Format] (4K)

OK, so here's hddsentinel complete log from the working 14TB WD Red Plus.If you mean the disk HPA, that one is supported, but not enabled:
