Im having trouble and here is the scenario... im using the DNS 321 as a file server for my DOS app... basically after mapping the driver by the "easy-search" i start the program, alter a few records (everything fine so far) and after 4-5 records changed the program pops up the msg: DISK IS FULL... and theres like 500GB left open... i have the latest firmware... is it clear? can anyone help?
