Err… CyanogenMod ROM damaged my 64GB exFAT SanDisk microSDXC Card again when I tried it on Samsung Galaxy S3. CyanogenMod ROM like CM9 or CM10 does not support SD card in exFAT file format. It can’t detect SD card at all. And when you restore back to Samsung firmware, micro SD card will be prompted as “Damaged SD card ~ SD card is damaged. Try reformatting it.” No worry, there is an easy way to fix this issue and recover your SD card back with all files and data intact…
