OK, here is the problem. Change the 2 lines above (starting with /dev,
watch the word wrap) by changing the fmask and dmask values. dmask is
the directory permissions, fmask is the file permissions. If you only
want write access to your data partition, only change the second line.
They are written in octal, subtracting from the mask value of 111. So
zero, would mean 111, i.e read, write, execute. A mask of 022 would
give rwxr-xr-x. Make your mask 002, to give rwxrwxr-x. So change the
fmask and dmask to 002. To make the change immediately effective (so
you do not need to reboot), you would need to enter this command as
root, mount -o remount /Windows/D (and mount -o remount /Windows/C if
you also change it). The you should see that you have write access.
You could see that by ls -l /Windows/D, and it should be a bunch of
rwxrwxr-x. HTH.
