snmp issue with 6.6.0

There is something strange going on here. I have given Netgear the benfit of doubt and loaded the MIB file that came with the 6.6.0 firmware update.

After executing snmpwalk -c **** -v2c -m "READYNASOS-MIB.txt" ip_address_of_netgear I still was only able to see the following paths

RFC1213-MIB::mib-2.25.2.3.1.3.33 = STRING: "/"
RFC1213-MIB::mib-2.25.2.3.1.3.36 = STRING: "/dev/shm"
RFC1213-MIB::mib-2.25.2.3.1.3.37 = STRING: "/run"
RFC1213-MIB::mib-2.25.2.3.1.3.38 = STRING: "/run/lock"
RFC1213-MIB::mib-2.25.2.3.1.3.39 = STRING: "/sys/fs/cgroup"
RFC1213-MIB::mib-2.25.2.3.1.3.56 = STRING: "/media/USB_HDD_5"
RFC1213-MIB::mib-2.25.2.3.1.3.57 = STRING: "/run/nfs4/media/USB_HDD_5"

This aligns with a standard SNMP Walk without the MIB File 

HOST-RESOURCES-MIB::hrStorageDescr.1 = STRING: Physical memory
HOST-RESOURCES-MIB::hrStorageDescr.3 = STRING: Virtual memory
HOST-RESOURCES-MIB::hrStorageDescr.6 = STRING: Memory buffers
HOST-RESOURCES-MIB::hrStorageDescr.7 = STRING: Cached memory
HOST-RESOURCES-MIB::hrStorageDescr.8 = STRING: Shared memory
HOST-RESOURCES-MIB::hrStorageDescr.10 = STRING: Swap space
HOST-RESOURCES-MIB::hrStorageDescr.33 = STRING: /
HOST-RESOURCES-MIB::hrStorageDescr.36 = STRING: /dev/shm
HOST-RESOURCES-MIB::hrStorageDescr.37 = STRING: /run
HOST-RESOURCES-MIB::hrStorageDescr.38 = STRING: /run/lock
HOST-RESOURCES-MIB::hrStorageDescr.39 = STRING: /sys/fs/cgroup
HOST-RESOURCES-MIB::hrStorageDescr.56 = STRING: /media/USB_HDD_5
HOST-RESOURCES-MIB::hrStorageDescr.57 = STRING: /run/nfs4/media/USB_HDD_5

I have attached 3 USB Storage Devices which I can see only 1 and I'm also missing the main Partion on the RAID

I'm not sure if this is deliberate to prevent NMS from accessing the appropriate data, but there has certainly been a change or introduced bug
