You can do what Gurban recommended, i.e. specify your username in the
options field of fstab, e.g.

/dev/hde4        /mnt/win         vfat        noauto,uid=hamid  1 0

or you can change the umask, e.g.

/dev/hde4        /mnt/win         vfat        noauto,umask=0022  1 0

Right, because empty (or unmounted) directories are probably a part of
your native Linux filesystem which supports these permissions. When you
mount another filesystem, the mount point assumes it's permissions.

Since FAT doesn't support the same type of permissions as Linux/UNIX
file systems, a umask, uid and gid must be set explicitly. Slackware
sets these so ordinary users can't access it by default.

It doesn't matter wether you used ext3 or reiserfs before since this
issue is related to the defaults set by Slackware and not the file
system you're using.

Good luck.
