I have a Corsair 8 GB Flash Voyager that I bought last year. It is primarily used for storing music. I keep it permanently plugged in my car HU (Clarion DXZ 785 USB). Once in a 2-3 weeks, I take it out to load new music and replace old folders. Of course, I unplug it only when the system is shut down, to prevent any loss of data.

My entire music collection is stored on my laptop. This is the Master Backup.

Today I faced a strange problem. I transferred some new music folders to the flash drive but when I plugged it in the car, it threw an "Error 2" and no music could be played. I unplugged it and tried to view the contents in my laptop.

The basic view shows all folders intact. However, when I open any of the folders, the files appear to have strange letters/symbols, and not mp3s. Please see the attached screen shots for reference. Many folders have no mp3 files in them! Basically I sense that the flash disk is corrupt. But when I did a disk check, no errors or bad sectors were detected.

I will format it and see what happens. But is this something serious? Do I need to get the drive replaced?
