the failure i had this past spring (pretty sure it’s upthread) was resolved with a new card. about a week preceding full failure W/ playback was almost constantly glitching (repeated clicks/cuts in the playback), then the module stopped responding or booting.
i get the same error @sellanraa reports on occasion, and while i have really done a lot of troubleshooting (it usually occurs when i’m in the middle of something i don’t want to put a stop to), its a repeated glitch as above for a few seconds at the start of a cue, so my big assumption is that a write error is produced under certain conditions.
i’ve got ~six months without another card failure but all our use cases are different and individual media is individual media. maybe not a super helpful contribution here but it’s what i got.
