I tried "sudo rm /media/sandisk/song.mp3", but get the "read only disk"
error message. I can copy files from the player to my home directory,

How do I use fsck.vfat?

After more messing with the directions on Ubuntu Guide (for manually
mounting Windows FAT partitions), in addition to the /etc/fstab editing,
I got this as "mount":

>>/dev/hda3 on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
usbfs on /proc/bus/usb type usbfs (rw)
tmpfs on /lib/modules/2.6.12-9-386/volatile type tmpfs (rw,mode=0755)
/dev/hda1 on /boot type ext3 (rw)
/dev/hda2 on /home type ext3 (rw)
tmpfs on /dev type tmpfs (rw,size=10M,mode=0755)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/sda1 on /media/sandisk type vfat (rw,iocharset=utf8,umask=000)

Directions followed for mounting it manually:
sudo mkdir /media/sandisk
sudo mount /dev/sda1 /media/sandisk -t vfat -o iocharset=utf8,umask=000

And yes, I checked---the "hold" button is set to off. :-)

Not sure what else to do right now... maybe permissions need to be
changed somewhere (or adding a user name(s) to a group, though not sure
how to do that exactly)?
