On rebooting my Samsung Galaxy S2 (running Villain ROM 3), I got an error in the status bar "USB Storage damaged. It may need reformatting". File managers like Astro fail to open the /mnt/sdcard folder.
Things I've tried so far:
Anyone encountered this issue before? Any suggestions?
Solved it myself after hours of Googling.
I really only needed to run error checking on the internal storage (CheckDisk) in Windows. Since I couldn't get Windows to mount the drive normally, I tried booting into ClockworkMod recovery mode and then connect USB.
Ran the error checking (Right click on drive, Properties, Tools, Error-checking), rebooted phone and voilà! Life is beautiful once again.
I had the same problem and I found a solution.
First, problem description: I've connected the S2 to a PC and turned on the mass storage mode. After copying the files I've selected on the phone to disconnect from pc (without unplugging the device in windows - which may cause this problem). After that I found out that both memories (sd card and 16gb usb memory) are damaged.
Solution: I have connected the phone to a pc, choose to turn on the mass storage mode. Windows found the drives but they are empty (unmounted). I selected on the phone disconnect from pc and this time I have unplugged the cards from Windows. After this my phone found the memories and start working again. I think it is a system glitch which hangs the card somewhere between mass storage mode and direct access to them.
