You have two USB mass storage devices: /dev/sdb and /dev/sdc. So of course trying to mount /dev/sda doesn't work. If mounting /dev/sdb doesn't work, it could be that the device isn't formatted. You might have to run mkdosfs /dev/sdb You shouldn't try to mount /dev/sdc; instead you should try to mount either /dev/sdc1 or /dev/sdc4. But first you will have to create entries for sdc1 and sdc4 in /dev, because they don't exist already: mknod b 8 33 /dev/sdc1 mknod b 8 36 /dev/sdc4 BTW, this would be much easier if you used udev.
