+==== 84 track seeking ====
+Not all drives will be able to seek 84 tracks without a small modification.

+{{:5_25_floppy_drives:teac_fd_55gfr:mod_84tracks_2.jpg?200|}}
+The modification can be performed by following these steps:
+  - Place a flat-head screwdriver on either side of the front spring that holds down the head assembly guide rods, as pictured.
+  - Tap the back of the screwdriver lightly but firmly to move the spring towards the spindle motor.
+  - Do this for both sides of the spring.
