Ghost Music Tracks??

[BigIan279]

I play all of my music via a mini 32Gb memory stick and as happens over time I got tired of a couple of albums so I deleted them using my pc (which BTW is how I added them to the stick).

The weird thing is that although they are no longer on the memory stick (and I've checked twice as I thought I was going mad), they still come up on the display and are played in the car. WTH?? I thought maybe there was some residual memory in the unit so in the hope that it would all be cleared I replaced it with a different memory stick with completely different music on it which played fine with no sign of any other music when I browsed.

I put the original stick back in and the "deleted" tracks are still visible when browsing and can be played.

The car and head unit has been switched off and on again without the memory stick inserted but still the same.

There is no mention made of any head unit memory the manual, so I am at a loss as to what this could be.

Has anyone else had this issue and how did you resolve it?

What file system are you using on the thumb drive?

What happens if you check on your computer but enable view hidden files and folders?

I've just copied over mp3's into folders all using Windows 10.
I've got all hidden files visible.

I was all set to recommend Disney's Chilling, Thrilling Sounds of the Haunted House!

Just for grins, try a defrag on the thumb drive after you delete the old files.

Or use Piriform CCleaner (free) to wipe the unused part of the drive.

You might try emptying the trash for the thumb drive. I bet windows just moved them to the trash folder-and the car can still see them there.

Even if you formatted the thumb drive the old files are technically still there, they are never truly erased the name is changed and they still exist until overwritten by another file, you can try just filling it up with other music or pictures or random stuff and then erase it and start over but even then it's technically still there. I can pull files off of just about any kind of drive, sd card, etc with standard software. same method investigators can see every website you have ever visited even if you wiped your computer, the only way to truly "erase" a file or history is to physically destroy the drive with a sledgehammer, drill, grind it up, etc. I use to use a program for drives that would fill the drive with "0's" so it could be used again no matter how it was formatted that always made it like new again.

"Quick format" just erases the file allocation tables while leaving the data in the clusters, but "full" or "secure" formatting actually overwrites the clusters. This is an option with Disk Utility on MacOS. I assume it's an option somewhere in Windows too.

kind of windows has a "quick" format or a extended one that checks for bad sectors at the same time. Both are useless security wise.
