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.

  • Corruption cannot cause the card to be un-formattable. You had a hardware problem, not a software problem. Buy a card from Kingston or another manufacturer who make quality stuff. Feb 25, 2011 at 16:19

MicroSD cards already have wear leveling at the hardware level - placing software wear leveling on top of that won't help much. Just get a higher quality microSD next time.
