Damaged files


Edited: Apr 20



I have a problem.

Today I was copying video files from the SD card and I noticed that some of them can not be read. From 30/03 to 8/04 they are good, and then suddenly until 18/04 all are damaged.

Message from computer: QuickTime Player can not open "2019_0418_171036_105F.MP4".


The file has a name, the right size but I can not open it.

I have SanDisk Ultra 128GB card.


Any ideas?

Please do not use Sandisk SD card for camera system.


1. It is not qualified for such loop video recording.

2. Sandisk warranty does not cover such using.


You can find below discussion and the statement from Sandisk.


This warranty does not cover use of the Product in connection with the following uses or devices (as determined by SanDisk): (i) normal wear and tear, (ii) video monitoring, security, and surveillance devices, (iii) internet protocol/network cameras, (iv) in-car recording devices/dashboard cameras/black box cameras,

Never knew that SanDisk exludes the usage in video devices from their warranty. That´s funny, because SanDisk itself offers theirs cards to be used in Action Cams or camcorders.

Left side you can choose host type "Action Cam" to see, which SanDisk cards fit this usage.


Nevertheless, I have always used SanDisk cards in my cameras (GoPro, Mobius, K2) without any issues. Maybe your sd card simply gets broken for some reason.

  • After the firmware v61 update, I noticed the blue light on the power transformer never goes off - no matter how long the bike is off. Is this normal? What could possibly be powering this other than my battery?
  • I'm at a slight disadvantage, as my bike is still in a container ship, travelling back to the US, but I'll see if I can make my point clearly enough. I've been told that if I connect to the K2, using WiFi, and the K2 App on my cell phone, that the time would be correctly set within the K2. I'm afraid that this is not correct, at least it's not correct under a few sets of circumstances. First of all, in certain parts of the world, you need to set your phone to override the current time, and set it manually. For instance, all of China uses a single timezone (Beijing time), but my iPhone got confused, and thought that there were multiple time zones, and so, I had to override the time setting. As a result, although I connected my iPhone to the K2WiFi, and then enabled the IOS app, and selected settings, I still ended up with a situation where the time on the K2 was at least 1 hour different from the time on my phone. Throughout my trip, I often tried to get the time of the K2 to be properly set, and I think that I achieved it only once. In all other cases, it was between 1 and 2 hours off. So, my question is, why don't you allow me to set the time, or select the time zone within the K2, rather than relying on using the Phone? As IOS versions on the phone change, it is likely that they'll handle time zones differently, perhaps forcing you to make odd choices in some cases, but if I was able to manually set the time zone in the K2, we eliminate any chance that the system will have the wrong time. The outcome, if you want to set the time, connect to the K2 over WiFi, set the time, and exit. It's just about perfect, and it addresses all of the possible irregularities that exist as we travel around the world. Thoughts?
  • Loving this product so far. Question is: I'm a dual-sport rider and often take my GS Adventure offroad. How does the K2 hold up in rocky, rough riding environments? Heading back to Baja next month, and I would love to have it fully functional but I'm considering leaving the DVR back at the hotel. Advice?
