Hello, y'all！

Welcome to the third installment of our hard drive series - and the one about one of the most frequently mentioned issues lately!

Who can't be anxious after installing a hard drive for a surveillance system, only to find that it can't be formatted, resulting in the recorder not recording properly? Don't worry, I've brought the solution today.

First of all, please make sure that the hard drive you are currently using is the original one shipped with the Zosi product, or did you purchase it on your own?

1. If you buy the hard drive from Zosi, please follow up the below steps to check it:

A. Please switch another working 12V power supply to connect the DVR / NVR system to try;

B.  Please disassemble the rear cover of the DVR/NVR to check if the power wire and data wire of the hard drive are connected well, you can re-connect them to try;

C. If the wires are connected well, but the hard drive still can't be formatted, please remove this hard drive from the DVR/NVR, then install it to your other device (DVR, NVR, or computer) to test if it can work normally.

If you have another working internal hard drive, you can also install it to the DVR/NVR to test.

2. If you buy the DVR/NVR from Zosi and buy the hard drive from another company, it can be recognized by our DVR/NVR system but can't be formatted, please follow up the below steps to check it:

A. Please tell us the brand, model and some specs of your hard drive;

* It will be better to take some photos of your hard drive to us, or send us the link of your hard drive;

B. Please check if the power wire and data wire of the hard drive are connected well;

C. If the wires are connected well, but the hard drive still can't be formatted, please remove this drive from the DVR/NVR, then install it to your other device (DVR, NVR, or computer) to test if it can work normally.

If you have another working internal hard drive, you can also install it to the DVR/NVR to test.

Of course, these operations above are simple preliminary troubleshooting and may not completely solve the problem you are experiencing. If after checking your drive still cannot be formatted, please contact us and provide us your order number / order ID, and help to confirm the model number of your DVR/NVR, we will send the correct upgrade file to you, you can upgrade the DVR/NVR to try.

Please let me know if you have any questions!
