Hello everybody, just joined this forum because I am desperate with a purchase I was enthusiast (and still am in some ways) until few days ago. I recently bought a PD, and upgraded to the 1.17v of the firmware. The problem is not directly connected to the firmware, which I just upgraded wishing it would solve my problem but it did not. I tried reading extensively the forum wishing to find the answer without bothering anybody, but even following all the advice I found here I did not manage to solve my problem that is sd card connected. Let's first say that I have a Mac, thus I was unable to follow the great majority of advice regarding formatting using guiformat insofar as there is no Mac version for it. I bought a 128gb (the top readable as far as I can read) sd card and when I first put it in the player it worked fine. I put songs inside and could see the card from the device (yes, minor problems with the file labeling and categorization, but really, as long as I'll be able to listen to my music I will not be that picky about these kinds of problems). I saw an extremely low charging process but still, after loading the files inside I could play and listen to them from the device. I then decided to charge files in my card without having the device connected to my Mac and I put the card in a reader. Unfortunately there was a problem during the copying of the files and everything crashed. This resulted in the card loosing even the files that I charged before, so I decided to format the sd card and start all new. I connected the card to the Mac and formatted it FAT32 as I read everywhere (I formatted it both from within the device or from within the card reader), but now, does not matter which file I put inside the card, the device will not recognise the card anymore. I would like you to notice that when I connect the device to my laptop it reads normally the two storages, one is "Plenue D" and the other "Sd Card", with the second having all the files charged inside. I do not think the card is broken or anything because otherwise it would not be read by the laptop either. Please give me some advice. Tell me if I am doing anything wrong. I cannot survive with only the 30gb storage of the internal memory.
