It seems bizarre to me that my SanDisk ClipZip will work right when I install a third-party firmware, but not when I use SanDisk’s own firmware. For example, playlists work perfectly if I’m using Rockbox, but pretty much not at all if I use SanDisk’s firmware, no matter what version I try. External cards still work fine in my device if I’m using Rockbox, but not at all if I’m using SanDisk’s firmware. I can add a file or two to my device without having to re-load the entire storage if I’m using Rockbox, but if I’m using SanDisk, the device has to look again at every single track.
The simple solution would be to just use Rockbox, but I’d like to be able to sync subscription files with Rhapsody, and that’s the one thing I can’t do with Rockbox. But it does raise the question, why are the people who are designing Rockbox as a hobby able to get this device to work right when SanDisk can’t?
