Avid MXF files in the Avid MediaFiles/MXF/1 folder have a separate track for each V, A, etc. so a VA1A2 file will have three mediafiles associated with it in that folder. When doing a reveal file from the master clip, in your case, it will find the first, then ask if you want to find the, the next and the next.
In your hard drive crash, did you lose files? Have you tried trashing the MSM files in the folder and letting them rebuild? Are you in HD or SD? Did you create MXF for the picture and OMF for the audio?
