i too have exactly the same issue, let me explain..
i was using my phone (xperia arc), browsing some files in gallery
then there was a random reboot, i thought it was an issue with the ROM,
all my apps were deleted(i was using sd-ext partition),
all the settings were altered (screen lock removed, all incoming call were blocked, and a lot of other things)
i thought it was some kind of VIRUS,
then in the end i discovered that my SD-CARD is showing exact behaviour as mentioned in the first post

- I removed the SD Card and attached it to my laptop's SD Card slot and tried formatting using Windows 7- the format process completed after ~30-40 minutes, yet the SD Card appeared UNCHANGED!
- I used multiple SD Card formatting tools, still no dice - they either complain about write protection, that they can't start, they start and stop halfway with an error, you name it.
i dont know what to do with it, tried almost everything, any help would be great!!
