Before you set up recording settings, please check if the hard drive status is normal.

Could you please go to Advanced-->HDD Info and check if the HDD status is 'Normal'?

​

If there is nothing on the storage or the status is not normal, it means something is wrong.
Please try the troubleshooting methods below.

1. If the hard drive is not from us, please make sure your hard drive is for surveillance use, not for PC use. The type should be SATA. SATA2(3GB/s) or SATA3（6GB/s）is recommended, and We recommend 5400 RPM and the brand can be Dest digital or Seagate.

2. If the status is unformatted, click format to format storage the hard drive. Please note that all recording files on the hard drive will be deleted after formatting.

3. Open the cover of DVR. Uninstall and install HDD several times. Here is the method: https://support.sannce.com/hc/en-us/articles/900000433303

4. Install the hard drive and put it close to your ear to check if you can hear some noise. One hour later, use your hand to touch the hard drive to check if it is warm. If you can not hear any sound and the surface of the hard drive is not warm, it can prove the hard drive is not even powered up. Please share our results.
