It's a Toshiba X300. You're more knowledgeable than me but I can't understand why it won't work.
Please connect it via (E)SATA to a Windows PC and execute the "fsutil fsinfo ntfsinfo x:" command. Then we can say something.
My own Q10 Pro is still floating around somewhere.
Can't find the details needed. It is a recent high-end model like WD Black and seems to be made by WD too (internal type number).
So the likelihood that it is a Native 4K HDD is fairly high.
sorry about delay been buisy
hopefully this info may be of some use to you
