As for the SD card failure - sorry to hear that. What adapter were you using?
SD cards can fail for a number of reasons and I try to back mine up at least every week. I’ve had them fail in cameras, music gear, and pretty much everything. I avoid the off brand cards you can buy for cheap on amazon now as a lot of those lie about the specs of the cards. Had a lot of these problems with the Empress Reverb needing a v30 card and then the cards on amazon said v30 but when testing the speed was v10.
