I've set up my /etc/fstab file as usual, so that I can
access my Windows C: and D: drives, as shown in the attachment.
I can mount/unmount both these drives and read them. I can
also write to the /mnt/c filesystem. But for some reason I
can't write to the /mnt/d filesystem. Specifically:
$ whoami
yawar
$ pwd
/mnt/d/My Documents
$ touch file
touch: creating `file': Permission denied
$
Can some kind soul tell me what I'm doing wrong?
Thanks,

******************
When you mount a fat partition under linux you mount a file
system that doesn't have inbuilt support for the permissions for
each file that eg ext2 supports.
Because of that you can give extra options when mounting fat
partitions with extra options.
Those options are shown in the man mount pages under the vfat
options section.
The relevant bit is this :
uid=value and gid=value
Set the owner and group of all files. (Default:
the
uid and gid of the current process.)
umask=value
Set the umask (the bitmask of the permissions
that
are not present). The default is the umask of
the
current process. The value is given in octal.
So when you mount a fat file system ALL files will have the same
owner,group and permissions !
If you don't want to use the permissions carried over from your
current user/process you'd use umask=value, eg umask=777 would
give everyone full read/write access.
So a changed entry in your fstab might look like this
/dev/hda5 /mnt/d vfat noauto,users,umask=777 0 0
if you want everyone to be able to mount it and have full access
to it.
