We need to figure out if it’s the card or the slot that’s the problem.
Do you have something else that uses microSD? A phone, a camera, a card reader? Try putting a song on that way and see if the Fuze reads it. Make sure the mp3 file has ID3 tags in ID3v2.3 ISO-8859-1. Some Linux taggers don’t use that format–although the tags shouldn’t matter in folder view.
My Phone have a micro SD slot and it was the first use i make for the micro SD card.
I put some song on the card, there were readable by the phone but invisible on the Fuze (without formatting between phone and fuze)
Then i formatted the card in FAT32 with the Linux Formatting Software (Gparted), and put a song which were in the internal memory of the fuze (i.e the ID3 Tag was readable), but nothing happens : when i move the song from the internal memory to the external card, the song disappears from the list of song available on my fuze.
At work, i’m on windows, so i formatted in FAT32 with the Windows Formatting Software (right-click>Format…) and do the same operation (Put a song from the internal memory on the card), but there were no more results.
Are you sure the card is plugged in all the way? The top edge of the card has to be pushed in sometimes slightly past the opening in the case using your fingernail. If you listen carefully, you’ll hear a faint click when the mechanism grabs the card. Release pressure slightly, and you’ll hear a 2nd click when it’s locked in position. To release the card, do the same thing; push in unitl it clicks, then ease up the pressure and the spring will eject the card. Don’t take your finger off of it though, as it will launch the little bugger across the room!
Not saying this is definitely your problem, but it could be. Happened just a few days ago here with someone else.
When you click on the card to Explore it, do you see the mp3 on it?
If you do, right-click on it and look for Properties/Summary/Advanced. It should have information like Artist, Album, Title, etc. Without those the Sansa will display the song as Unknown.
You need to have a second uSD card to troubleshoot. 2GB uSD’s are cheap and commonly available, and you should be able to borrow one from somebody.
You don’t have to format or do anything to the new card (all uSD are formatted to FAT or FAT32 to be usable). Just plug it in–the uSD should be flush with the Fuze, i.e. nothing sticking out–and go into Folder view. If the card has folders, it will be shown in that view. Files would need to have a recognized extension (mp3, flac, etc) to show up.
If a uSD works w/ your PC but not for the Fuze, sounds like the problem is w/ the Fuze. But you can only be sure with a second uSD.
Congratulations !!!
You’re right : my card is bad !
I tried with another one and it works …
I think it’s weird that i see the card as an Hard Disk when the fuze is plugged on my PC but is not seen by the fuze.
Whatever, i’d like to thank all of you for your help.
