I have a SamsungGalaxy S3 (32GB Verizon version, not rooted) with a 64GB external SD card.
I use the external card only for music, which I load from my computer. Several times now I have lost files from the external card. Is there any way I can force the S3 to mount the external card as "read-only"?
Ideally, a widget that would allow me to toggle the mount from RO to RW and back would be perfect, but any way to mount it as RO will satisfy my need to protect the data on the card.
