SQL Server 2017 - sys.dm_os_enumerate_fixed_drives
by BF (Principal Consultant; Architecture; Engineering)

Iteration #1:

SELECT * FROM sys.dm_os_enumerate_fixed_drives;

Msg 3634, Level 16, State 1, Line 3
The operating system returned the error '21(The device is not ready.)' while attempting 'GetDiskFreeSpace' on 'A:\'.

Workaround: You can disable the virtual Floppy drive from the Device Manager and re-run.

Iteration #2:

SELECT * FROM sys.dm_os_enumerate_fixed_drives;

As you can see there are duplicate records being returned from this new DMV and Microsoft will address that.

Note: This new DMV is a replacement for XP_FIXEDDRIVES.
