800k floppy malfunctioning.

Hi folks, drive in question is the 800k Sony MP-F51W.

It emits a very loud whine, I believe from the drive head, if you place your finger on it, you can feel a vibration, similar to an ultrasonic toothbrush.

Upon injecting a disk, the drive spins up, quite fast. The drive head remains stationary no matter where it is positioned, it doesn't seek.  After about 5 seconds of high speed rotation, it ejects the disk.

Any ideas?

Thanks!

Is the head physically jammed? Are you able to move it manually with your hand? Is the drive motor worm gear able to move freely or not?

Worm gear moves freely without any resistance.
