 ====== YE Data YD-380B ======
+The YD-380B is a 5.25" double sided high density floppy drive made by YE Data.
+It uses a metal belt to facilitate head movement and locks the disk with a lever. Head loading is done via mechanical linkage.
+It uses the [[#pn128206-01_rev_b|TPN128206-01 Rev. B]] control board and the Sankyo SB68A motor board.

+===== 84 track seeking =====
+Unmodified drives will not be able to seek 84 tracks. A major modification is required to enable this.

+{{:5_25_floppy_drives:ye_data_yd-380b:mod_84tracks_2.jpg?200|}}
+The modification can be performed by following these steps:
+  - Mark the current position of the stepper motor in relation to the drive body.
+  - Unscrew the stepper motor.
+  - Unscrew the springs that hold down the guide rod of the head assembly on the stepper motor side.
+  - Move the head assembly and guide rod out of the way.
+  - Use a rotary tool to grind down the head assembly end stop as pictured.
+  - Clean the drive of any metal dust.
+  - Put the head assembly and guide rod back in place.
+  - Screw down the springs that hold down the guide rod of the head assembly on the stepper motor side.
+  - Screw down the stepper motor so that it can still be moved with some friction.
+  - Reposition the stepper motor in relation to the drive body using the marks done earlier.
+  - Screw down the stepper motor all the way.
+  - If the positioning isn't done right the tracks have to be re-aligned.
