Hi all, first time poster, but not first time Droid user. So far this forum has been a good resource in figuring out some of the bugs with my Razr M (which I like a lot more than my previous Droid X) but I'm having a problem that I haven't seen anybody else post about.
I use a 32 GB SD card as external storage for pictures, videos, and music. My phone is my mp3 player and usually my music source when I'm in my car, so it's important that it works good. Over the last couple of days, my SD card has crashed several times when playing mp3 files. I've not had a problem with it crashing if I already have a playlist of files set up and I just let them play and turn off the screen. Where I'm having a problem is if I'm accessing different songs every few seconds, eventually the SD card crashes and none of my files on my SD card can be displayed.
This has happened in 2 different music playing apps under the same conditions noted above (constantly switching to a new file). Those 2 apps are PowerAmp and Bubble UPnP. I haven't tried it in Google PlayMusic yet because I can't stand that app, but that will be next. It may be an app problem - but when this happens, none of my files (pictures included) can be displayed. I go to my files app and all of my files are there, but none of them can be opened or displayed (pictures included) from any app on the phone. The first time it happened, I powered off the phone and then turned it on and it fixed the problem. The second time it happened I tried to unmount the SD card and then remount it. When I remounted it without removing the card, it said I had a blank or nonformatted SD card (can't remember the exact wording). So it took the card out and re-inserted it and it mounted fine. The third time it happened, I turned the phone screen off and let it sit for half an hour. I came back to it and my files were suddenly working fine again.
Any advice is appreciated. I have used the PowerAmp app before on my Droid X and had this problem maybe once or twice in 2 years of use. I consider that an anomaly, whereas with this phone it seems to be easily duplicated over and over.
