Hello
I upgraded both disks to 24TB but My Book Duo shows total space only 44TB as if two 22TB disks were mounted.
Is there firmware update for My Book Duo, so it works properly with 24TB disks?
24TB disks Red Pro and Gold versions were introduced recently in 2024.
Largest My Book Duo is still sold with 22TB disks.
Are you going discontinue My Book Duo? What is going on?
LOL thanks mate, I thought only Toshiba cheats 
Please look at photo from Techradar review of 44TB retail version (two 22TB disks).
This is before formatting, before configuring, just put brand new 22TB disks into enclosure, on the retail box says clearly 44TB, in the app says 40.02TB.
So almost 4TB disappeared, just by installing disks.
Clearly they use decimal notation and mean TB not TiB, clearly WD app says TB not TiB.
Here screenshot from their app:
