I recently had to move the NVR, which involved removing power. On restart it started the dreaded HDD problem beep, presumably because it ran a fsck on power-up or something. I've disabled it as per Amcrest's instructions but this seems like a rather unsound way to deal with it. Obviously a lot of people have this issue or the linked web page wouldn't exist, but is there something more I can do to diagnose and possibly repair the problem? It's a 4108-A2, I can't find anything obvious in the disk-related menus that allow you to do much, the only obvious thing in the SMART menu is that "Reported Uncorrect" is set at 2 which is more than zero but not really a cause for alarm on an SSD with x million sectors that's only storing throwaway video recordings.
Recording and playback work as normal, but responding to an error indication by disabling the error warning seems like a bad idea. In particular if there's a more serious failure that does need attention at some point there's no way to tell.
HDD warning, now what?
Re: HDD warning, now what?
Couple of things. First and I have said million times, While normal SSD use in a DVR/NVR isn't a good idea. While SSD might be better faster and all when it comes to the use in a PC. The DVR/NVR don't work a HDD or in the case of a SSD the same as a Computer does..
Second are you 100% sure that the alarm you are getting is in fact for your HDD? Was did the alarm go off and you looked at the alarm menu and or Logs and at that moment in time there was an HDD error listed? I ask because If you had Login turned on and you have your system connected to the INTERNET not meaning just giving it Internet access but I mean where your DVR/NVR is the main internet IP because if you have that alarm active it could be a warning that someone is trying to gain access...

Re: HDD warning, now what?
I used an SSD because it produces close to zero heat (meaning it doesn't dump even more heat into an already hot-enough NVR enclosure) and no noise or vibration, and because I had one lying around. I'm only recording on motion detect which means it only gets a handful of writes every day. In particular it probably gets fewer writes in a year than a single boot of a PC causes in a few minutes.
The alarm is definitely the HDD because when I disable the HDD alarm as per the linked web page it stops, when I reenable it it starts again.
Another thing that's specific to the 410x series AFAIK is that "removing power" for these models means yanking the power cord out because some genius decided there shouldn't be any proper way to turn them off. This may have caused a glitch that affected the SSD. Or at least it's been running off the default config which forces a reboot every day at 2am without any alarms being triggered, it's only the power off + on again that caused the alarm to trigger.

Re: HDD warning, now what?
Problem is that isn't the case. You see when you setup a HDD in a DVR/NVR that system spins 24/7. What we don't see behind the case is that the recorders are always spinning mainly because when setup the device is setup to record a set time before the action happens. Normally 4 seconds as setup from factory.
How can that happen Well in some devices there might be a Sleep option and in that case it would cost more because the system has a Memory that it saves the data too while the HDD is sleeping. However the Amcrest and most other DVR/NVRs that I use spin the HDD and is always recording data to all channels that are running. Once action happens there is a pin that is set 4 seconds before event starts and then runs and pin drop to where the event ends.
About the alarm, If it only happens on a Reboot and want to keep the HDD alarm enabled. I would then move the Auto Reboot time setup for a time that no one is normally home. Say if you are working between 8am to 5pm and no other person is normally home between 7am and 3pm with school, Then I would setup the reboot time somewhere before 3pm. This way no one is home for most of the days that the system reboots and beeps.
I have most of my alarms turned off. I keep an eye out for Logs with errors. I do use Log in Alarm only on devices that I am testing on the Internet. Once I remove from the internet I disable that alarm as well.
About removing the power for the recorder is something that really isn't an issue. Normally the device is running 24/7 and if needing to replace a fan, or HDD or just take it down from where mounted to do a System Cleaning. Setting the device to shut down and then pressing the power button on a Power strip or removing from outlet. However to be honest pulling the plug from machine is ok and might even be better because of the power that could remain in the power supplies caps.
