I have a 4G fuze with latest firmware (2.01.17) and an 8G uSD card, both are reaching their limit of capacity.
I had an album that could not fit on either the internal or card completely but I had enough free space that I could spread the album over both and it would fit.
I transfered the first 14 songs to the card then the rest of the album I transfered to the internal memory.
When I tried to play the album the Fuze ignored the track numbers and listed song 15 first, after the last song of the album it listed song 1 that was on the external card.
I consider this a bug, if the Fuze is going to read the track number tag then read the track tag, don’t give the songs on the internal memory a higher priority than the track number. One or the other please Mr SanDisk.
