OptionalerrorIf there are non-critical errors while extracting metadata, those errors may be added to this field.
OptionalfstypeThe type of file system on the volume, like ext4, apfs, or ntfs.
Note: on Windows this may show as "ntfs" for remote filesystems, as that is how the filesystem is presented to the OS.
OptionalisIndicates if this volume is primarily for system use (e.g., swap, snap loopbacks, EFI boot, or only system directories).
Note: This is a best-effort classification and is not 100% accurate.
Mount location (like "/" or "C:").
OptionalstatusOn Windows, returns the health status of the volume.
Note that this is only available on Windows, as both Linux and macOS are
prohibitively expensive, requiring forking fsck -N or diskutil verifyVolume.
If there are non-critical errors while extracting metadata, those error messages may be added to this field (say, from blkid or gio).
VolumeHealthStatuses for values returned by Windows.
A mount point is a location in the file system where a volume is mounted.
