SanDisk Micro SDHC Card doesn't display tracks names.

I feel more secure using the original firmware when transferring files, especially on the Clip Zip. Some have had issues with files they transferred using Rockbox on the Clip Zip. As an extra precaution, I also use the original firmware for transferring files to the Clip+. I don’t transfer files that often, perhaps less than 10 times a year.
