Check following items.

5-1. First of all, make sure the drive icon of the floppy is displayed in the My Computer window normally.

If the icon is not found, make sure that the floppy related BIOS settings;

even if the write-protection of the diskettes are enabled. In the worst case, the motherboard may also be damaged.

5-3. If accessing the drive does not turn the LED of the FDD on, the power cable or the interface cable may not be connected properly. Make sure the connection. Note that wrong connection may break motherboard.

5-4. If you have another standard 3.5" 1.44M FDD, it is good idea to replace to your own FDD instead of the YD-8V07 and to confirm that it works fine in order to judge whether the YD-8V07 is broken or not.
