Do you have any tips regarding hard disk settings on Hikvision recorders?
Yes, for the audible warning. We typically recommend turning off all audible warnings on Hikvision recorders and only enabling the "HDD Error" audible warning.
The reason for this is a simple one. If one day, your client calls you to report the recorder is beeping, and you know the only audible warning enabled is for a failed hard drive (HDD Error). then you know to bring a replacement hard drive when going to the location to replace the defective one.
