Issues with the same SD card again. "Check SD card". Now I'm thinking the damn disc must be faulty.

Does this alert come up even if you disable your audio alerts in settings?

It makes no difference if you have alerts set to on or off. It's reporting that there's something wrong with the recording on the disc. When the message comes on, recording stops. The message just repeats itself until you turn off the unit. Only solution is to remove the card & reformat.

I've read this entire thread, don't think anyone has asked this (stupid question I guess):
If I wire the BlackVue to my car so that it is powered 24/7, the only way to turn the camera off is to pull the plug (at the side of the camera) correct?

I have the dashcam plugged in through the cig. lighter now, so when the car shuts off so does the camera: "BlackVue powering down". If I have to pull the plug, is this essentially the same as powering down by turning the car off? I guess what I'm getting at is.. is it ok to shut down by pulling the plug while the camera is still on and recording?

It is not so good as a backup cam - the main use I was planing for it.
Why? No left/right mirroring (making my head go round), about 30 seconds delay for starting up, and last but not least - so-so visual performance at night.

Besides, having rear dashcam is fun, but not very useful. I guess good backup cam will be a better replacement.
After all we are living in the center of the Universe.

I have a theory, but could not confirm it. If you still haven't formatted that card, could you try this ?

Copy a video file to computer, rename it, and copy it back to the same location on the card. Clock how long it takes to write that 50mb file back to the sd card.

If it takes more than 40-50 seconds, the card is fragmented and it becomes too slow to write files.

I tested the oem Samsung class 6 card. It is ok for sequential write, but terriblely slow in 4k random write. Close to 0.06MB/s, which is far from enough to write required 7000bps bit rate video files.

I c I c. I'm planning to get a rear mounted cam to double as a backup as well.

Those that have check SD card problem, which overwrite setting did you set in your blackvue?
Overwrite old files base on time or Have a set % for Normal/Event/Parking recordings?

I have always used the default option, which is overwrite files based on time.
ie. oldest files get overwritten
So far, I never had any check SD card problems with original Samsung 16GB class 6 or my current Sandisk 32GB class 4. Both has never been reformatted, even when updating firmwire. BTW, I am using 1.040e, no problems so far. Well, I have never had any problem with my unit. Now just waiting for July/August to really test the unit under 65C inside the car.

I am guessing that if you use the other option of have a set % of storage for N/E/P recordings, the video files gets fragmented over time because the Blackvue has to find the "appropriate" location in the SD card to overwrite the old files. Then eventually lead to check SD card problems and have to reformat.

I have two cams. One has done the check SD card once and the second has now asked 4 times. I would say the first cam gets more recordings since I drive more whereas the 2nd cam (wife's) gets less and yet has to be reformatted more.

Both cards are set to default, which is re-record based on time. Both have the original 16gb class 6 cards.

It's a nuisance and I have real no problem reformatting the card... I just have a problem if the card stops working while in drive and then there is an accident.

Again, I'm suspecting it could be a problem with the card itself, not the unit.

Try formatting with the card formatter from their site, and then upgrading to 1.40e. It's been ok for me so far...

I already mentioned this theory once before. I think that many if not most corrupted SD card problems are caused by interruptions in power and voltage spikes when ignition is turned on. My BlackVue is hooked up to a power source that is not interrupted when I start the engine. I also ensure to allow BlackVue to boot up completely before I turn off the power to it (if I need to for whatever reason).

Would you dare to pull your desktop's power plug many times during the comp's boot process just to see if it will recover alright next time it's plugged back in? Every time BlackVue is powered up it creates new files on the SD card. File creation is a flimsy process. If power is interrupted during this step then it might result in a corrupted file system. Why take chances? Let you comp boot completely before shutting it down, meaning connect your BlackVue to a power source that doesn't flicker when your start your engine.

So far I have never had a problem with the "check SD card" error, and I'm on my fourth firmware.

This might be a possible cause. I had my Blackvue hardwired with PMP, and it has been flawless so far. No check SD card issues at all.

Its funny, I was going to dig up your earlier post as it wasn't really discussed. I think you might be on to something. I have mine wired to a constant and my cars lights do not flicker when starting up.

I've never had the SD problem. I've been through each of the firmwares and have never had an sd card problem. I format my card 2 times a week.

1.40 has been solid, that 1 hour issue is resolved as far as I'm concerned. I even catch plates at night sometimes.
Autocorrect sucks
