exfat vs fuseblk

[Paolo Galtieri]

I have several external disk drives from the same vendor.  According to 
the vendor recent drives are formatted exfat while prior ones where 
formatted ntfs.  According to what I find on the web file system type 
fuseblk should work for both exfat and nfts. I have a new 12TB drive and 
when I plug it in mate-system-monitor reports it as type exfat not fuseblk.

What determines whether a file system type is reported as exfat, ntfs, 
or fuseblk?

The drive works fine and is accessible from F34, I'm just curious why 
mate-system-monitor does not report it as type fuseblk.

Any help is appreciated.
