VC fails to quick format above 16TB in Windows

[Michael Dannov]

I bought 3 16TB drives to use in a raid pool and any storage space (something I have done with VC for years without problem). But if I create any partition above 16TB, quickformat in VC to NTFS as a Standard Veracrypt volume errors out.

I tested different sizes. This happens only when the size of the partition is above 16TB and it does not error with ExFAT, but I cannot use ExFAT.

I attempted to quick format as none instead, mounted the partition as T: (the mounted VC volume), then attempted to manually quick format the drive from command line to get a better idea of the error. I've shown it (at bottom)...

Please note, this error only happens when I attempt to quick format the VC mounted volume, not the Windows volume. If I quick format the Windows volume (without VC mounting), there is no error.

[As a sidenote, I quick format after VC encryption formating each drive individual (faster).]

Using Win 1909 (Same problem with first release 1503 as well).

C:\WINDOWS\system32>format T: /q /A:8192 /L
The type of the file system is RAW.
The new file system is NTFS.
