Adding a NAS to the USB Port

   What's the file system on the volume?

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual (at least).  Read.  Look for
"USB device requirements".  (Note that APFS and exFAT are not among the
supported file systems.)

   I can't (yet) see your pictures. In-line images must be approved
by a moderator before others can see them.  The time required varies.
Attachments have no such limitation.  Of course, attachments have their
own one-per-message limitation.

   That depends.  RTFM failure?  High-quality software?  If you want
NAS, there's much to be said for investing in a real NAS box, as opposed
to trying to deal with Netgear's dancing-bear ReadySHARE stuff.
