Hi I noticed this problem as well.
The default snmp from windows does not supply the information on mounted disks.
A workaround is installing SNMP informant.

Below you find the bash script that i use to check the disks via snmp informant.

you find the disks paths by running a snmpwalk -v 2c -c <community> <host> 1.3.6.1.4.1.9600.1.1
