nostr:npub1w5p2xgn2hkddv5ced2527rrclk7gkjup7qntgqxcdcu40jvnwsssrz7gzp I do come across devices that will not accept a Linux formatted FAT32 USB or flash card. When I format in Windows, works like a charm.

I've looked into it but never came up with much of anything. Search engines think I want the 'how to format a USB device to FAT32 in Linux' tutorials.  No.
