Encountered an issue with my sansa fuze+ in ubuntu 10.04. Yesterday, my fuze+ mounted just fine in ubuntu. Today I plugged the device into a usb port and ubuntu recognized that the fuze+ was plugged in to the computer, but ubuntu would not mount the device. I tried formatting the fuze+ and resetting it to no avail. I tried connecting using both MTP and MSC modes and the problem persisted. I solved the problem by manually mounting the device in a terminal window.
The first thing to do is create a mount point in /media called “fuzep” using the following command:
sudo mkdir /media/fuzep
The second task is to determine the name of the device using this command:
sudo fdisk -l
This command will list every drive on the computer. Look for a fat32 device. My fuze+ was listed as " /dev/sdc1".
The third step is to mount the fuze+ to the previously created mount point:
sudo mount -t vfat /dev/sdc1 /media/fuzep -o uid=1000,gid=100,utf8,dmask=027,fmask=137
This process manually mounts the fuze+ to /media/fuzep. I don’t know if this process renders the fuze+ visible to applications such as rhythmbox or not, as I don’t use that function; but I am able to copy files to the fuze+ just fine.
