I have two 64 Sandisk extreme 3 cards that now show as cannot read in the p4p or the pc, has anyone else had this problem, I have not had any problems with lesser size cards, all purchased from amazon

if they are less than a year old, ping amazon, if no help, ping sandisk. I have experience an SD card go bad once, long ago, and it was one of those "whatever" brands.....

I will see what sandisk say, I purchased 10 months ago, only used in drone so not had that much useage

I have started to format the sd card each time I insert one for each flight!

Just to clarify, what are the read/write speeds of the card. Based on your wording, they were working before? Do you recall noticing the change after a firmware update or a hard landing?

Extreme plus or just extreme? 64GB?

sandisk extreme U3 xc1  They replaced with extreme Pro version, I dont know when they failed, I have never had a hard landing, always catch in hand

I just got the sandisk extreme U3 xc1 v30. (64gb) I'm shooting 4K 60fps. For whatever reason, my footage skips every 2-4 seconds.. Any advice?

Your Drone requires Extreme Pro Cards NOT Extreme. Sounds like your cards read speed isn't keeping up with the cameras write speed? Extreme 60MB/S in contrast of what should be Extreme Pro 95MB/S.
