+==== Mount to NTFS Drive with permissions for specific user and group ====
+NTFS does not have Linux-compatible permissions, so when you mount with a normal NTFS connection, you have wide-open permissions. To make the NTFS drive look like it has a specific owner and group, use something like this:
+   mount -o uid=userid,gid=groupid,dmask=022,fmask=133 /path/to/disk /mnt
