Wrong PartitionCount output in windevblk_test.exe
Environment
- Windows 10 LTSC 21H2 64bit on VirtualBox
- Microsoft Visual Studio Community 2019 Version 16.11.16
- 3 Disks attached
Problem
Drive 2 (\.\PhysicalDrive2) is a newly initialized disk, which doesn't contain any partition at all, but the test exe reports that disk has 4 partitions.
