Check the +5V voltage in the ST and check the 3.3V LDO regulator.

Re: Gotek burn hot arm chip
Have you the necessary stuff to diagnose the problem ? (a voltmeter).
If not i recommend you to get another gotek and avoid to plug it into this ST.

Re: Gotek burn hot arm chip
Take care that pin 1 of the ribbon cable goes to the pin 1 on Gotek... original STfm floppy drive had this connector upside down, so you either have to mount Gotek upside down or twist the ribbon cable. If you plug the cable as it was in original FDD, you are shorting all I/O pins to GND, what may damage the STM chip. Look at the color stripe on a ribbon cable, and not at a notch on the plug.
