Eachine E520S not saving to sd card

Hello, new here. I am getting into quads, and already ran into a bit of a snag with one of my first crafts, an eachine e520s 5G 4K. I got it to work for the most part, but using the LW FPV app (which crashes far too often on my samsung galaxy S5) to take pictures or video results in everything being saved on the phone, despite having tried 3 different sd cards so far, a 128GB samsung and two 64GB sandisk ones. The cards are properly inserted into the quad, and are always empty when I take them out to check on my pc. Could anyone shed some light on this? Some settings I've missed perhaps? Thanks in advance!
 
Check that the card is formatted in the right format for the quad you may have the option to format it once in the quad
 
I have the same problem. I have done some testing and found with an old 2gb card that it will only accept FAT and FAT32 formats. It will record pictures, but only creates unplayable video files. No actual video to watch (1kb files). I assume the problem with the video is that it is really an old card and probably very slow. When I format a newer 32gb card in the same way, it doesn't record anything. Doesn't even create the Picture/tmp/video folders. Also tried using guiformat.exe to format the 32gb and a 128gb to FAT32 and nothing. All out of ideas for now.
 
Update: I was able to get both my 32gb U1 and my 128gb U3 cards to record pictures by formatting them in FAT32 with Linux. They create the folders but still will not record video and create unreadable .mp4 files. The pictures are not "4K" depending on what your definition of 4K is. They are 2560x1440 which is the loosest sense of the term. I would appreciate if anybody can shed some light on this because I know very little about formats/resolutions/etc. and am taking shots in the dark as to why the video will not record. And to clarify, everything works fine through the app, but it is only recording the stream to the phone/tablet, which is 480p and I would like to record directly to the SD card at full resolution.

Are you trying to playback with VLC or something else, do the mp4 files have a reasonable size or look to be crazy small files?
 
Hmm don't have one of these but best guess is it is making the file when it starts up but never writes or finalizes updating the file description so maybe some way to trigger end recording without pulling power? Just guessing since sometimes runcam split can forgot last bit of video or get corrupted files from unintended battery ejection
 
I kinda thought the same thing so I took a short video (10 seconds), landed and just left it for about 10 minutes to see if it needed to process the file or something. No luck. I have given up on it and am going to return it. It is either broken or it is a p.o.s. Either way, it shouldn't be this hard to get it to work correctly. Thanks for your input.
 
I also had a problem recording to SD card. So I tried about 3 types and the result is here:
- working 8GB (Class4) Transcend
- working 64GB (Class10) microSDXC UHS-I Samsung
- the card format is FAT32 by default
- a directory is created on the card after inserting: "X: / video and X: / tmp"
- * .mp4 file is saved in "yeardatetime.mp4" format when recording starts
- video is MPEG4 (H.264), 2560x1440 (3.7k), 20fps, 8.197kbps
Slow Transcend write speed (but video is smooth), Samsung works 100%. Good luck to everyone :-)
 
Tried Aliexpress Z579 128GB U3 Class 10 micro SD FAT32. Using rec button on remote but nothing happen.
Videos are recorded just on my smartphone (dont know where ...)
Going to buy Samsung 64GB class 10. What's the product code?
Thx
 
I was having all these same problems, I tried about 6 different cards and none worked properly, but I've found a simple solution:

Banggod actually recommends exactly what card to use on the product page.

- Must be FAT32 format.
- The maximum capacity is 32GB.
- The UHS Speed Class must be "U3"
- Use the Windows operating system to format the SD card. Select FAT32 & 32kB unit size. DO NOT Select the “Format Option -- Quick Format” .

Once I followed these instructions, I had no problems.
The card I am using is: SanDisk 32GB Extreme microSDHC U3 (SDSDQXL-032G-Q46A)

UPDATE:
I still had some problems, sometimes it worked sometime not. I noticed that bright outdoor scenes would always fail, but indoor stationary photos/videos would be ok, so I suspected it was a data rate issue. I tried cutting a small hole in some black tape and put it over the camera. This worked great, no more failed videos outdoors. This also seems to support my suspicion that it's just a data rate issue. Low the data rate by covering half the camera or try and find a faster SD card.

Here's my story - I hope some of you find this interesting and is applicable to some of the comments in here...

I recently received an Eachine E520S from Banggood. At the risk of being kicked out of here - here's the blog entry which is ongoing... it's not an ad, I do this for fun.

Ok, so as a complete drone novice, I picked up this Eachine device and tried it across the road from my house in (very) rural UK, just a few feet from the ground and it was after that that someone in Canada asked me if I had a license! Turns out I may be ok back in rural UK if I'm sensible -something to note for the future.

Anyway, the first thing I noticed after recovering from the excitement of the drone actually working, was the usable but not-exciting quality of the video sent to my Pocophone mobile phone. It was at that point that I first fitted an SD to the drone (read the instructions - always a good idea) - it turns out that this quality gripe is common to many drones - limited bandwidth due to the WiFi connection back to your mobile phone.

Now I had my SD in place - worries over. Except they were not as I could not get anything out of the SD - my own fault for not formatting the SD and giving it basic directories.

The definite fix is referred to in the above-linked blog, but in case that link gets killed (I'm new in here) - format the SD as normal (FAT32) on a PC. I also used a good (but inexpensive from Amazon) SD - a 16GB Sandisk Ultra - class 10 - the same type I regularly use with Raspberry Pi (also covered in the blog). I created folders video, tmp and photo. That may or may not be essential but trust me it works. By the time I finished messing with the SD, I'd missed the best opportunity to capture my pal's hall in Northumberland which was to have been an idylic British location to demo a drone - typical British weather, just as it looks like summer is here, winter returns. In the blog are embedded short video segments of my attempts, for better or worse.

In my early dealings with the drone, I bashed it off my roof a couple of times but it SEEMED to be ok, the only issue being that it would OCCASIONALLY drop for no good reason (not battery, not range, no obvious visible damage other than a tiny blade dent). I took care of the drone as best as a beginner could - as I wanted to save it for my trip to sunny southern Spain where I am now.

A couple of days ago I took it out for a spin near our rural home here in Spain - no problem - again without any SD - I'm in the process of updating the blog right now. This morning I put in a cleanly formatted SD and did a short test - excellent quality video - rubbish content - the next logical step was to take it into the brush area (no-one is out and about up here - I checked) in the middle of our area up in the hills. I sent the E520S (which auto-returns when out of range or when the battery is getting low) over into the overgrown brush valley area, with enough height to ensure there would be no mishaps - and started the local video recording. After an apparently excellent 10 minute performance, I was just starting to have the drone auto-return to me, when, out of no-where, the "dropping" issue returned and it simply fell out of the (completely calm) sky.

Ok, my rubbish logic here - I sent it over the area as it was so inhospitable, there was no chance of anyone being down there.. the fact that this meant there was also no way of spotting and retrieving the drone in the event of a mishap, somehow escaped me at the time - and now, it's too late. Two helpful (and fitter than I) neighbours later, we simply could not find the drone - and to be awkward, it would not even attempt (as it has done successfully in the past) to get back up in the air.

My NEXT drone is getting an alarm bell fitted. Of course as the Eachine comes with spare blades I COULD have fitted them but as a beginner, the very SLIGHT dent I'd put in one of the blades did not seem an issue, in future I'll not be taking chances - but of course, the yearning to send the drone somehere inhospitable was just too much for me to bear. I usually learn the hard way.

This got a bit long - I hope it answers any SD-related questions. With photos, videos, Raspberry Pis and now my sorely missed drone, I've yet to go wrong with genuine class 10 or better Samsung or Sandisk SDs.
 
I thought my SG 907 Max was broken - I had tried 3 Micro SD cards. However, the fourth card worked!

It won't write to many of them or write with errors.
I found that it works great with my SAMSUNG EVO PLUS 32GB card.

Now it records videos at 1920x1088 @29fps and photos at 4K without issues, and apparently as long as I want to the microSD card.

Ando & Jackson have the basic info.

Your drone's SD card must be:
1) Within its maximum GB capacity rating,
2) Fast enough to record from the drones camera,
3) Correctly formatted. (Usually FAT32.)

Your drone manual, or the manufacturers website, will give these specifications.

4) And stop the video before switching off the drone !

Also, my Eachine E58 needed major heart surgery before the SD card would fit properly in its slot.
