HELP! Trouble.

Hello dear All! After replacing the mother, SN stopped working with Spec's floppy disks. Grit Internal error 204... At the same time, AMD01 reads and writes everything. Disk2trd reads, but Trd2disk says I can’t write. Has this happened to anyone? Is there any way to treat it? Help me out, otherwise I almost have to give away points, but here it is... p.s. Sorry if it's offtopic. See you again All!
