Please forgive me for being a noob here on this forum. I did a search and couldn’t find any info on my issue, so I’m posting here now… :smiley:
I’m having trouble writing video files (MKV, MP4, etc.) to the external micro SD XC card that I’m using with my SanDisk media drive. The first few files that I write onto the SD card transfer and play fine on the media drive and my PC (I’m using VLC). After about 10GB or so of data has been transferred to the card, the files copy over, but they won’t play. VLC tells me that it does not support the video format “undf”.
I’m using a SanDisk 64GB micro SD XC card spec’ed to 30MB/s (formatted as exFAT). I have two of these cards and they both behave the same. I’ve also tried 128GB HC (formatted NTFS) cards to the same result. Nothing seems to work as expected. What am I doing wrong or missing here? I’ve been battling this issue for weeks and its driving me nuts!!!
