This often happens in FAT and NTFS media that was not properly
unmounted when removed from the previous device. For a Windows
computer, that means clicking Unmount (or whatever it is) before
removing the media from the computer. For many mobile phones, you must
power down the phone before removing the card.

I the flash media is not properly unmounted before being removed, the
filesystem will panic when mounted. Linux plays it safe and mounts
read-only in this case. It's bitten me more than once! And that is a
good thing, as Windows computers will mount the drive r/w and I have
twice seen data corruption as a result.
