Ray, in the KN7000 folder of the SD card, there is a file with the name KN7000mn.inf. That file contains, among other things, all the long names for the SD card content. When it becomes corrupted, you usually lose all indications of SD content. There is also a KN7000mn.bak file that is a backup of the .inf file. If you delete the KN7000mn.inf file and rename the .bak file .inf, you may be able to recover the song names.
