The micro-SD flash memory chip that came with my new smartphone has some interesting issues with data integrity. I mostly use it to store sound files in the mp3 format, both pop songs of a few MB each and podcasts taking up tens of megabytes. And while listening to podcasts, in the middle of them, I have repeatedly come across three interesting and disturbing errors. The flash memory makes psychedelic remixes of my sound files!
- As I listen to one mp3 file, I suddenly hear several seconds from another file before the original recording resumes.
- As I listen to one mp3 file, I suddenly hear several seconds from a deleted file before the original recording resumes.
- As I listen to an mp3 file, the audio suddenly becomes pitched down to a barely comprehensible guttural grunt for tens of seconds.
These changes to the original files are permanent and always recur in the same way. With audio files, it's mainly just a nuisance. But there was GPS map data delivered on that chip too. I don't think it would be very useful after spontaneous random remix with snippets of mp3 audio.

Several weeks ago I tried once again, after many prior ill fated attempts over several years, to get a device that would play music, audio books, and be a radio. The audiobook part wasn't the most important part, but the ability to play various audio files AND act as a radio AND not be a big giant…
Since getting a smartphone, I never use my iPod anymore. (I handed it down to Junior who is now getting a psychedelic musical education. He's into the Marbles.) But the switch of course led to a huge drop in the ease of use. Here are the steps I have to go through to get my phone to play my mp3s in…
The first two sound like an addressing problem but the third sounds more like a problem with the audio codec (unless the data read access is totally farked up). The simple test would be to swap memory modules.
