Yesterday I noticed that I destroyed my just a couple of months old 32GB large microSD card. I wasn't even able to create a new file system on it or change the partition table, so it became completely unusable.
To prevent this from happening again, I want to use a different, more flash-friendly filesystem on my new microSD card. I am using an unrooted Nexus One with Android 2.3.3 on it. I know that it is quite possible to use different file systems with custom ROMs on rooted phones, but I want to use the official, unrooted version of Android.
So my question is: Is it possible to use other file systems than FAT on a microSD card with unrooted Android? Which file system would you use then to save the flash memory from corrupting?
I am also interested in things you do to save your microSD card life.
