My SG9663DCPRO is beeping intermittently now. Last time, the 400 GB card was going bad. I notice gaps in the recording on this one now, and have tried to use the SD card formatter. Unfortunately it takes a really long time and I can't not use my vehicle that long. If any one has advice from their experience, or the manufacturer, I would like to know. Thank you.
 
SanDisk Ultra 400 GB microSD XC. I can give you the tiny numbers on the back if needed.
 
It has an "A1" logo on its red & gray front.
 
ok, can you format the card and test it with CrystalDiskMark and let me know the result?

was the card supplied with the camera?
 
I used the SD official formatter tool to do a quick format before CrystalDiskMark, since overwrite formatting will take far too long. I would have to take tomorrow off work for it to finish that way.
 
OK, it is this:

that's well below what they typically do, when you get a chance can you do an overwrite format with SDformatter and then run CrystalDiskMark again and see what it does
 
Freaky memory cards can back them self into a ditch like that, why haven't we seen this before ?
 
I will let it run today and just drive without recording.

I had a Samsung card do something similar - that is write speed well below published specs - that was causing erratic camera performance.

SG9663DR update

For several years now I've been running both a standard front facing dash cam along with a telephoto dash cam. Usually the telephoto works in concert with my normal dash cam as an "enhanced" auxiliary cam but on occasion one camera really captures what happens when the other one doesn't quite do...

Started it at 8:48 am, it is now 7:48 pm, or 11 hours. It has done 33% overwrite in that time. So it should be done nearly exactly this time tomorrow.

unless you have a really slow card reader that might be an indicator of how slow the card is, does take some time but that seems excessive

If he's using a USB reader that could be the issue, especially if it's USB 2 versus USB 3. I always do my formatting and testing using the computers SD card slot.
 
I am using the little plugin reader that came with the camera in a USB 3 port.
