How can I prevent android apps from reformatting my SD card? I have a 32GB micro SD card, and some of the apps I use state that they have permsisions to modify sd card memory. I have a lot of personal files on my card, and the other day, some app, I don't know which one, had practically wiped out over 15gs of files from my card! 

How can I block apps from wiping out my sd card? I don't see what possible good can come out of an app that can wipe out all my personal files. I backed up my pics when a guy at work told me an app had re-formatted his SD card. Sure enough, the same thing happened to me. I was able to back up my files BEFORE it happened, but how can I prevent this from happening again?
I've never heard of an app that formats the sdcard. The permission to modify the sdcard is so the application can "read/write" data to the sdcard. 

If you have an app that formats your sdcard, I would report the issue to the developer, plus to the Android Market.
