Gibberish SD card name & folders after formatting

After formatting various SD cards, the S2400 reads a gibberish string of text as the name, and gibberish named folders show up on the SD card.

SD cards showing this behavior:

  • SanDisk 32GB SDHC Extreme UHS-I U3 90MB/s V30
  • Samsung EVO

This issue first showed up for me as a byproduct of bug report 5841, when testing alternative SD cards. Pics and descriptions can be found in that report.

Firmware at the time was firmware 2021-11-22 and 2021-10-09.

Have you tried an earlier firmware before October?
