Hello and Welcome. My name is ***** ***** I'll assist you today. I'm sorry you're having trouble with it.
Probably yes, because your problem is related to HDD and camera may ask you to format the HDD during reset process and it will erase all of recordings on HDD. I'm sorry for this news but have to break it.
I trust my input will help you out. Please feel free to respond if you have any additional questions.
