I have been using my ultraplus 9200 for about 5 years now, with no issues. I have always accessed the on-board Hard drive via my network to copy files to/from. However recently I find that I an access the 9200 from the network, but cannot access the HDD folder. IMG, NET, USB1-3 all work OK but if I click on HDD I just get a message "Location is not available. The specified server cannot perform the requested operation.
I have double checked all the network settings, but everything looks OK.

Any help appreciated.
