What are the reasons for choosing one USB mode over another? My clips came set to Auto Detect; there are MTP and MSC available. I found as previous post noted that they both dont show all the files at same time time. My music all seems to show under MTP mode which I think the PC sees as a clip. In MSC it looks like any other drive and shows as F: on my PC.

I was wondering what the letters mean and what are characteristics of each and why choose one over another.

One thing I notice in Autodetect which I guess is MTP the clp is seen as a clip and sometimes the music organization doesnt seem as I type it in. Would changing to the mode where it is seen as a drive instead of a clip have anything to do with this, or does the clip just do what it does regardless of how it is typed or what mode it is in when connected to PC.

Specifically, when I rip in WMP it goes in my rip folder as Album\Artist\Song and I put the Artist\Song folder in Clip, not the Album, and I name Artist and Album the same.

If I have an Artist A/song and an Artist B/song I find they do not appear as Artist A and Artist B but only as Artist and then both songs are under simply Artist. Seems like it knows more about the song than I do and goes by its own idea of where it should be. This is frustrating to say the least. Maybe it isnt something that can be changed.

One thing i was wanting to do was have songs by same arist in different bitrates so i could compare, but they all go under Artist no matter how I name them and I cannot tell them apart on the clip list. I can rename Artist 3 ways, rename song 3 ways, but only one Artist and 3 songs show with only the basic names and not the renamed.

Sorry if this sounds confusing but it is as clear as I am able to make it at this point. Maybe some suggestions and answers will result. Hope so.

USB Modes :  Auto, MTP, MSC

Auto will attempt an MTP connection to your computer first, if its not possible it will revert to MSC.

This is taken from the Sansa Knowledgebase:



Question   When connecting the Sansa to the computer, should I have the USB setting on MTP (Media Transfer Protocol) or MSC (Mass Storage Class)?  

Answer   You should have your Sansa player set to MTP (Media Transfer Protocol) when you are using it with any of the supported subscription music services. The main purpose of MTP is to transfer media files and associated metadata to/from devices, with optional additional support for reading and setting of device parameters such as special DRM-related device parameters for restricted content

Otherwise, you should set it to MSC (Mass Storage Class), which is the normal USB mode for storage devices. 

I don’t do DRM,  but I still keep my USB mode in Auto   (MTP connections to my PC)   and do everything I want.   But I do very basic stuff,  I drag and drop, and don’t use a music library like WMP,WinAmp, iTunes, or Media monkey for syncing.

Thanks. Meanwhile here is a practical example.

I created some song files using a DVD I recorded off TV to DVD player to AdsTech Instant Music USB with no further preamp into a WAV editor and made a wav uncompressed file. Saved as LAME 128 cbr and vbr, 192 cbr and vbr, 320 cbr and vbr, and original wav. All in a folder named FILES. I made a cdrw of these but did not rip. Instead I copied them into my 8 GB clip MUSIC file. Clip USB set to Autodetect.The songs were of same song named 01Songname ,02Songname,…  to recognize them later. They were only songfiles, 7 in all, in a folder named FILES and are the only music on clip to avoid confusion. Plan to play and compare.

This showed up in clip as Artist > Unknown > 01Songname, 02 Songname, 03 Songname, … Thought is might show as FILES though since I named folder that.

Original problem here was I had made an entire Wave Editor recording at too high level and got scratchy swishing noise in some or maybe all of the songs.Having traced it back to original transfer and not what I did to the files later, i see I have to do it all again.

A sideline problem though was undestanding the WMP ripping and naming, the USB modes and what they mean and what influence they might have on inputting songs and naming albums or artist folders.

Many times I would get several different songs all with same names or or multiple artis folders or unknown artist, or some other confusion.

I am not sure if there is a question here but maybe my experience may help someone else to figure things out or lead to some sugggestion, advice, or solution that may help me as well.

Literally have to just puzzle and work it out yourself with some help from others. 

Apart from the audiobooks and podcasts folders, the Clip generally ignores the folder and file names for its display’s organization of your files; instead, it uses the ID3 tags.  No way around that, although SanDisk has looked at the possibility of adding a folder view.

Note:  this has nothing to do with USB mode.

Where are these ID3 tages located - on the CD? Because I am not connected to internet to get them, and some songs have been taken from VHS recordings from TV, yet there is information added that I dont know how got there. Cant figure how the clip can know.

The tags are embedded within the MP3 files, either in a block right at the end of the file after the audio data ( or, more commonly these days, at the start of the file before the audio data (

Now if you’ve created the MP3 files yourself, especially if you’ve used LAME, the files will have audio data but no tags yet (it’s possible to add them with LAME when you encode them, but it’s clumsy).

In Windows Explorer (not Internet Explorer) you can right-click the headings on Details view, and display Title, Artist, Album Title, Track Number, etc.

You can also edit the tags in the properties dialog, by displaying the Summary tab, clicking “Advanced >>” and then clicking on the Music fields.

But the preferred tag-editing tool for users on these forums is mp3tag.

If you rip your own music, many rippers also have the option to fill in the iD3 tag info. for you, grabbing the info. from an Internet music database.

There have been many posts here on ID3 tags and how to create them; it’s easy to do.  Recommended that you do a serach here (box at upper left) on ID3 tags or MP3tag (the popular tag editor mentioned above).
