It might be the indexes are stored (but not the actual files) and that's what's showing. Have you actually tried playing the deleted file(s)?

Inserting a different flash drive and having that indexed should clear the old information, you can then insert the modified original drive and have it reindexed in it's current state.

 

The funny thing is that those files will play. I try your suggestion and I'll let you know how it pans out.

 

Do you have a Windows based system? When you did the format was it a 'quick' format? If so the data is it's not really erased from the device - the FAT is reset and the space is made available for reuse. Sounds like that may be what's happening since the data is still there the head unit is using the stored index to go directly to it even though the PC shows nothing.

It may also be the RDX has undocumented internal storage and actually saved the original USB drive contents and does not recognize that it's changed. This is just speculation on my part.

 

Well I have tried a full format, I did this using exfat I will try it again with the full format but this time as fat32. According to the ELS folks there is no built in storage in the RDX like there is in the MDX. But hey who knows. The system does seem to be very picky with the file formats. I will post when I try another stab at reformatting.

 

Doing a full format fixed it.
thanks for the inputs!
