Many other users using that LR-16 without the problem what you explained above. There was a known issue with some previous firmware release when the user deleted some recording from the HDD then the next recording had dropouts. That LR-16 performance (and our other products as well) depend on the firmware version, so I strongly recommend to update the firmware if you need more reliable operation. I can provide more accurate answer if you updated the firmware and you still have a similar issue.
