Get-Volume displays exFAT file system type incorrectly as 'Unknown'
When a removable drive is formatted with exFAT, the Get-Volume cmdlet incorrectly displays the FileSystemType property as 'Unknown.' The FileSystem property correctly shows 'exFAT', it is the FileSystemType property (two different properties) which incorrectly says 'Unknown.'
Format a USB flash drive with exFAT, then run:
Get-Volume | Select *
