I recently picked up a 4GB Sandisk MicroSD card, plugged it into my Express, connected my Express to a USB port and successfully copied nearly 4GB of music. When I tried to use it, it started acting strangely, turning off and on, and rebuilding the database repeatedly. I figured that I might need to update the firmware to support the 4GB MicroSD so I downloaded the software. It got to about 50% complete and hung. I tried running it on another computer, but it wouldn’t even recognize that the Express was plugged into the USB port (although I hear a ‘ding’ from Windows when I plug it in, but the device never shows up in the Explorer or device manager).
I have tried the hard reset repeatedlly, I have put my older 2GB microSD card back in, taken both out, all combinations thereof, to no effect. Right now I have a cute little Sansa Express brick. It won’t power on and I get no display on it when I plug it into a computer.
It has performed flawlessly up to now. Can anyone offer any ideas?
