Okay, so this one's a weird one.

 

A friend came to me with their 8GB USB flash drive and said that it has about 60 songs on it, and they want to copy them onto their computer. They have tried plugging it into both Windows and Mac machines, and they're able to see the picture files that are also on there, but no audio files at all.

 

I have plugged it into my machine and can confirm that there's a few hundred pictures but not one audio file to be seen.

 

The weird thing is, the can plug the flash drive into their car's audio player and the music immediately starts to play from the flash drive. Unplug it, and it immediately stops. (So we know the car hasn't copied/saved any files to some sort of internal storage.)

 

I know the audio files are on there, we just can't see or copy them...

 

I tried using Recuva to scan for audio files, I have confirmed there's only one partition on the flash drive, and the only hidden files are the random system files generated when you plug it into a Mac.

 

Does anyone have an idea of where the audio files are hiding? There's some super obscure music and special recordings on this drive so he gave me permission to send it to a data recovery lab if necessary, but I want to avoid that expense for him if possible.

Did you show hidden files in Windows?

Attach the USB flash drive. Open Disk Management. How many partitions are shown on the flash drive?

This might be an incredibly stupid suggestion, but I'll give it a try.

 

Are you sure that among the photos aren't the songs as well. However, they might have thumbnails and you can't distinguish them from the thumbnails of the regular photos?

 

90% this is not the case, but check it out anyways and good luck!:)

The partition shows the full 8GB of space, there is no unallocated or unknown space, correct? 

 

How big are the each of the picture files? In Windows do you have File Extensions shown?

It's good to explore every possible option, but no, the photos are really all actually photos.

Copy one file from the USB flash drive to your desktop. Change the extension to mp3. Does it play?

 

Another option is to download Testdisk. Unzip the Folder and Run PhotoRec, not QPhotoRec. Your USB flash drive will probably listed as sdb or sdc. Select Whole space. Any files it can find will be placed in the unzipped folder of Testdisk.

 

Download the 32bit version even if you have 64bit Windows.

 

Any files recovered will have generic names but have the correct extensions. You will need to rename the files accordingly.

No, it doesn't play. If I open the file, it is actually an image.
