Sansa Fuze+ "no uSD card" error

The history of this player and micro SD cards is ridiculous. When I first bought my Sansa Fuze+, I had no trouble at all with micro SD cards - I even used a 64GB class 6 card that I already had and it worked like a charm. And suddenly, no cards have worked right since that first one got fried in my tablet.

I chose this player for several reasons, in no special order: the compact size and smaller screen in particular (I like watching movies on airplanes and not having people watch over my shoulder); ability to take micro SD cards and various file types; sale price; and NOT an Apple product. I am seriously doubting my decision now because I can’t use it for the purpose that I bought it, which is to put all my mp3s on the internal memory of the player and use the SD cards for videos. I can only use the mp3s, and they fill the 8 GB.

I thought I had figured it out in pieces, but now my theory is shot to pieces. I thought, after buying new cards and having them fail to read, that you can’t use class 10 at all, but class 4. So, I bought class 4 and 32GB to make sure. I have a brand new Kingston 32GB class 4 and it can’t be read. I reformatted the card in my pc to FAT32, and it reads briefly, but I can’t put any files on it and have it read in the player. I try booting first, then inserting the card. Then, I try inserting the card then booting, and finally, I try plugging it into my computer and reading files from there (which works maybe 1/3 of the time).

I formatted the card in my PC using SDFormatter and GUIformat (to get FAT32). Then, I formatted it in the Sansa when it reads. I figured out that the Sansa doesn’t read it so well when I format it in the device, so I also tried leaving it formatted to FAT32 from the PC and it seems to read at first that way, but suddenly stops as soon as I move files over.

What is up with this player not reading cards??? Anybody have a magic trick for this? Something I’m missing?

Perhaps you could try the following: boot, insert card, remove card, re-insert. That might help, or it might not. Also, see what happens when you connect it to your computer as an MSC device, and see if you can read the contents.

It’s possible that the issue is being caused by some weird hardware failure. If that’s the case, you may be able to get a free replacement if your warranty is still valid (2 years for Europe… I think; 1 for America). If your warranty has expired, you don’t have much to lose by trying Rockbox. If it’s a software issue, and not a hardware one, Rockbox should do the trick. See HERE for installation instructions

I should mention that I have never had issues with SD cards and the Sandisk firmware, so I’m guessing it’s a hardware issue.

Recently got my new Sansa Fuze+ 16GB and purchased to local store a Sandisk Ultra 32gb class 10 M HDSC. Recognised by PC and formatted in fat32 no problem. Fuze+ who doesn’t recognize it. Lastest firmware and RockBox installed. I tried my small 2gb and it’s recognized. So why this 32gb doesn’t work on my Fuze+? Is it the class 10? I’ haven’t seen any references about type of HDSC or Sd class for Fuze+!

Most likely. See if you can exchange it for a Class 4 card.
