C128D Floppy Drive issue

[Timtheloon]

My C128D floppy drive is not working and looking for some assistance with it.

When I start the computer the drive LED just constantly flashes.

I have used the 1541 Diag cart and I can make the drive head move and can see the floppy disk spinning but it doesn't want to read it doesn't seem to try to attempt a read

I've cleaned the heads the drive itself was clean inside.

Anyone got any other ideas I could try?

The computer seems fine otherwise

 

[generac]

U8 logic 7406
Normal looking startup (LEDs and motors) and computer resets drive but no access, 74 DRIVE NOT READY error.


U16 logic 7406
Normal looking startup but spindle doesn't run. Although computer resets
drive, access shows DEVICE NOT PRESENT error. Partial failure: computer
locks up when drive accessed.


U14 logic 7407
Normal looking startup but no read in 1571 mode, reads in 1541 mode but no write or format (21 READ ERROR). Can also cause disk ID mismatch after disk swap.
