Ubuntu – Changing file permissions on USB external hard drive


I am using an external USB hard drive for a long time in Ubuntu 10.04, both at work and at home. Now I've installed 12.04 at home. Today I used the USB drive for the first time. I can read the disk but can't change the permissions of a file I wanted.

Output of "mount"

/dev/sdb1 on /media/FREECOM HDD type vfat   

I try

sudo chmod u+w bsst-hdf_to_bsst-h5

and I get

-rw-r--r-- 1 paco paco  2956 dic 19 10:27 bsst-hdf_to_bsst-h5

Any ideas would be appreciated. Thanks in advance.

Hi again and sorry for the delay in answering. Now I have tried to copy the device line from fstab from 10.04 to the laptop with 12.04 but still get an error message.

Error mounting: mount exited with exit code 1: helper failed with:
mount: only root can mount /dev/sdb1 on /media/FREECOM HDD

The line I add to fstab to try to mount the usb drive is

/dev/sdb1 /media/FREECOM\040HDD vfat rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,flush 0 0

When restoring original fstab and pluging the usb drive the output of mount is

/dev/sdb1 on /media/FREECOM HDD type vfat (rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks)

What should I add in fstab to get the drive fully working? I wanted to change permissions on files in the usb drive.

Thanks again
