My app showing HDD exception after a short power cut yesterday?

[suggysnr]

My app showing Hdd exception after a short power cut yesterday, and I have that annoying bleeping have nothing on playback I have tried to identify using the search for exception. Shows nothing. My hard drive is showing abnormal with Zero total capacity and zero free space
I have had recordings in the past.
Can I reboot or something similar.
Thanks

Some DVR's/NVR's support "Rebuild database" it will do something like "Defragmentation" does on windows machines.

It might help it out.

But if you dont have that option or if its greyed out since status is abnormal. These are next steps:

Bad sector test full scan:
-If everything comes out normal, reboot DVR/NVR, if HDD still shows as abnormal, plug to SATA2 port if your DVR/NVR have one.
-If nothing helps, uplug HDD and connect to PC and find guides how to export data which is on HDD. Usually expensive procedure if done by proffessionals.
-If footage isn't something you cant live without. Then do a HDD format.
-If even after all that its abnormal, then it can be 2 things. Either HDD died, or SATA Controller did. In order to know, you should plug in new HDD and see if it works.
-If Sata controller died, time for a new DVR/NVR


ps: Zero space is normal, as HDD oldest footage is overwritten. And once you fill HDD it will always stay filled up.

Good luck.

Thanks trempa92. Did a sector check then rebooted my machine —sorted. And old recordings still there and the bleeping warning sound has gone.
Don’t think it is connected but Any ideas as to why I can’t fast forward videos to see a particular incident on my app on my phone. I can do it in my monitor/ tv . Does my app need updating perhaps.
Thanks again

Your NVR firmware has to be compatible with fast forward plus application updated.

Ok. I don’t really understand that but thanks anyway. The firmware is 05 I think, if I’m looking in the right place. But can’t understand why it works on my monitor but not my phone.

If i explain why it does not work, it will become even less understandable. But ok lets give it a nice try:

Hikvision devices comunicate with hik connect cloud via OpenAPI which is available for integrators to get documentation on it.

Depending on device firmware, certain functions and nodes are possible via OpenAPI.

If firmware is too old and you have lets say a new node that is something like /ISUP/videoPlayback/speed/2/DeviceID=235425-HJER-324,...(just an example) that server is issuing to the hik device directly, that device will respond with either 400 Bad request or 404 not found.

Thats why its not even shown as posibility on hik connect for that firmware, so that end users wouldnt be hit with error messages.

I hope it gives a picture how it all works behind.

PS: 05 isnt firmware version. Firmware version will look something like v4.20.001 b201134 (example)

Cheers,

Wow. You know your stuff. And you type fast.
I have done a firmware upgrade check and it is the latest . I have also updated my app still doesn’t allow. I said 05 because the firmware was showing as V4.20.02, build 210705. Thanks very much for your explanations. I think I’ll just suck it and live with it. Take care.
