Seems everyone missed the fact that you were using ONE and THE SAME HARD DRIVE, which happens to be external. I don't see how the "Folders" would have changed.

When you are NOT using separate Computers to SIMULTAENOUSLY import Discs, which IS the case here, this is, "In reality," what happens when you Rebuild a database and, during the rebuild, "duplicate" BookIDs are found.

Under the above scenario, it would be impossible to have Dupicate BookIDs. So what is happening is, Hoster found a degraded Header and does not process/add the Song to the Songs.MDB. So, now, you have to reimport the Song.

So, one could conclude that ReBuilding the Songs DB would be something that one doesn't want to do lightly.

I haven't rebuilt my Songs Db in over a year.

If you DO NOT rebuild the DB, Hoster will PLAY any Song that has a Degraded Header, because Hoster uses the Songs.MDB to queue the Song. And, since the Song is STILL in the Songs.MDB, by not having REBUILT the DB, it PLAYS.

This is why I suggested to, and, I don't know how to make it more simple, copy the Songs.MDB.
