I know this issue has come up before, but I've yet to really find any true solution to resolve it. Ever since I upgraded my RAZR to 4.1.2, I have had some compatibility issues with the SD card. The phone will be reading the card without issue for a period of time, then all of a sudden the phone will stop recognizing the card at all. I will occasionally get a notification stating "sd card is blank or has unsupported filesystem". Rebooting the phone does not resolve the problem, nor does simply removing then immediately reinserting the card. If I remove the SD card from the phone and plug it into the PC, all my content will appear safe and sound. Usually after my PC recognizes the SD card, I can plug it back into my phone and it will start to function again for a period of time. However it will eventually stop working again, and I will have to repeat this process by plugging it into my PC.
I believe the problem originates not with the SD card, but with the firmware update itself. I do not recall having this problem prior to the update. I've learned one quick way to produce this problem on the phone is by plugging the phone (with SD card intact) into a PC via a USB cable. If the phone transitions to "USB mode", it will usually have a hard time recognizing the card after I have disconnected the phone from the PC.
Upon researching this problem on the web, the most common suggestion in correcting this problem is simply offloading all the content off the card to the PC and then reformatting it (either via the PC or the phone itself). I have not yet tried this method as results that I have read for it have been mixed.
I was wondering if anyone has yet to successfully pinpoint the cause of this problem, and have found a suitable solution for it.
