Het is me gelukt!
Door te googlen (dank je wel tukcedo) naar e2label kwam ik op het volgende....
These drives should be renamed either in Windows, using a partitioning tool or using "mtools" for Ubuntu, which works for FAT32. To do the last find the device name of your drive/partition, e.g. for a usb memory drive "/dev/sda1". You can use the "mount" command to do this, which should display all that is mounted. Then just do the following assuming you have /dev/sda1:
sudo apt-get install mtools
cp /etc/mtools.conf ~/.mtoolsrc
gedit ~/.mtoolsrc
Add the following lines to the bottom of this file:
drive i: file="/dev/sda1"
mtools_skip_check=1
Then do:
mcd i:
Now you can check the label using:
sudo mlabel -s i:
and change it with:
sudo mlabel i:name_of_your_choice
Cheers
