I didn't properly unmount a new external disk which I mounted like:
jeremy@jr:~$ sudo mount -t exfat /dev/sdc1 /home/jeremy/exfat
FUSE exfat 1.2.3
and now I am stuck -
jeremy@jr:~$ df -h
df: /home/jeremy/exfat: Transport endpoint is not connected

udev 3.8G 0 3.8G 0% /dev

I can't go forward (mounting) or backward (unmounting) -
jeremy@jr:~$ sudo mount -t exfat /dev/sdc1 /home/jeremy/exfat
FUSE exfat 1.2.3
fuse: failed to access mountpoint /home/jeremy/exfat: Transport endpoint is not connected
the mtab file looks like
jeremy@jr:~$ more /etc/mtab
....
/dev/sdb1 /home/jeremy/exfat fuseblk rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096 0 0
my primitive grasp of matters led me to try:
jeremy@jr:~$ ls /mnt
sdb1
jeremy@jr:~$ umount /mnt
umount: /mnt: not mounted
jeremy@jr:~$ umount /mnt/sdb1
umount: /mnt/sdb1: not mounted
jeremy@jr:~$ umount /home/jeremy/exfat
umount: /home/jeremy/exfat: Transport endpoint is not connected
since the disk now appears at /sdc1 after i unplugged/replugged it in the vain hopes that that would clear the /etc/mtab entry I tried:
jeremy@jr:~$ sudo mount -t exfat /dev/sdc1 /home/jeremy/exfat
FUSE exfat 1.2.3
fuse: failed to access mountpoint /home/jeremy/exfat: Transport endpoint is not connected
yeesh - this is worse than mating dogs
seems to have done the trick, a hint in that direction from the os instead of 'not mounted' would have been great
