I think you might be describing differences between MTP mode versus MSC mode.
MTP mode (default) relies on functionality provided by WMP to access files on the device. While it is integrated with Windows Explorer, it is not really mounted as a file system and thus does not have all the same properties and functionality as a normal removable drive.
MSC mode make the Clip function as a normal USB flash drive. It is mounted as a true file system, so anything you can do with files on your hard drive can be done with files on the Clip.
MTP mode is required if have DRM protected files (Rhapsody, subscription services, etc.) or if you want to use WMP to manage the Clip. If you don’t like WMP and you do not need DRM support, you might prefer MSC mode.
Note that your computer will only see files added under the respective mode. If you want to switch modes you will probably want to move all your files off the Clip, change modes, then add all the files back.
You can change USB modes in the System settings menu on the Clip.
I think you may be correct. This has always confused me.
On my Settings menu, that option has “Auto-Detect” highlighted. So I have always assumed that the device would know better than I.
I do not have any copy protected material. So I suppose I should select the MSC mode. I am not clear on a couple of points though. Will my ID3 tags still be used? And do I have to Format the Clip?
I appreciate the advice
