All right guys, let’s play nice!!!
How is everyone this morning? I am more interested in a device that is having difficulties reading the microSD than whether the device is on or off during the card swap.
So, who is right? The card can indeed be inserted with the device powered up. In a different platform, a laptop computer, the card is routinely swapped with the computer powered up in use. A laptop will query the card as soon as it is found on the bus. The Sansa does exactly the same thing. I only add one caveat: if the card is being read when disconnected, I can see how the Sansa could freeze while playing a file from the card, necessitating a soft reset.
If the Sansa is off, the card will be read as soon as the device is powered up. The player will refresh the music database whenever the card is inserted, even if it is the same card. This is because the Sansa hibernates when off, and does notice the change of card status.
The biggest problem with hot swapping a memory card is simple: file corruption caused by a card being removed before a write cycle is complete. If there is a card mounted in your Sansa, and you are plugged in to the USB port, this is the one occasion where there is going to potentially be a write cycle. Just be sure that the writing operation is done.
Overall, there are less opportunities for problems if the Sansa is powered off when swapping a card. If you have a device that is having difficulty recognizing a card, by all means, see if it recognizes the card after first powering up the Sansa. Just don’t try changing the card while the Sansa is reading the music database, wait until that is done. Mount the card after the display shows that your Sansa is ready, and it should begin refreshing the database again as the card is clicked into position. On the new Fuze+ , the display will state “loading card”.
The microSD card reader slot is a tiny, intricate little guy. It’s tricky the first time you install a card. The first time you install one, gently slide the card into the port, with the logo facing up (connector surface on the bottom). The raised edge is outward, of course. Gently press inward, and as the card is fully inserted, you will hear a soft click, then another click as the pressure is released. If mounted correctly, the raised outer edge should be about flush with the outside cover of the Sansa. To remove, gently press inward, and you’ll hear a click as the card is unlocked for removal.
If you have a Clip+ that will not recognize a card, especially a brand new one that is empty, try checking for the card with the Sansa plugged into the USB port. In MSC mode, you should see the card listed in Windows Explorer as a separate memory device. Most often, it will be listed right after the Sansa, but I have seen a computer with plenty of drives listed, an the expansion card is out of sequence. In MTP mode, it’s easier: you will see Internal Memory and External Memory, and you can then check the card.
If you have a card reader, either a handy USB multi reader, or an adaptor, you can try addressing the card directly using the PC. SanDisk cards are formatted, right out of the box, with the 2GB or less devices formatted as FAT, and the SD HC cards formatted as FAT32. If you run into a new card that’s supposed to be HC, and it’s not FAT32, beware- it may be a 1 or 2GB card counterfeit.
