ZOSI ZR08AN rebooting randomly

It was cause of wrong formatting procedure.

1. Put out all cameras first
2. shutdown system and eject power plug
3. replace HDD
4. plug power and boot up
5. Format HDD
6. reboot after succeeded for formatting HDD

That’s all

I was connecting camera while formatting.

I tried changing camera, check connection, changed power supply location, but I can’t figure out problems.

But reason is very simple.

Don’t connect camera while formatting.
