Note : Once set to read-only, the HDD cannot be used to save recorded files until it
is set back to read/write (R/W). If the HDD that is currently being written to is set to
read-only, the data is then recorded to the next HDD. If there is only one HDD
present, setting it to read-only means the recorder cannot record.
