take ownership of directory

Ive somehow lost ownership of a directory on an ext3 drive attached to my asus n56u.  I have terminal access to my router, but have very limited knowledge of linux.  there are a total of 4 folders on the drive.  I have write access to 2 out of 4 of the directories.  If i run a frisk -l, i get

Disk /dev/sda: 2000.3 GB, 2000398934016 bytes
255 heads, 63 sectors/track, 243201 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks  Id System
/dev/sda1               1      243201  1953512001  83 Linux

how can i switch to the drive and get ownership of the troubled directories?

You need to access the system as user root, then mount the filesystems, then as root you run

chown -R username:groupname /filesystem_mount

You need to put actual username , groupname and filesystem_mount

To list the ownership:
# ls -lah /
