Something that I used long long years ago into my "Discovery" program for formatting floppies.
Line 100 run an example of disc formating, so take care about your floppy before a RUN 100.

5 ' FORMAT (DATA/VENDOR/IBM)
6 ' DATA type=&C1 (9 sectors/178K)
7 ' VENDOR type=&41 (9 sectors/169K)
8 ' IBM type=&01 (8 sectors/154K)
9 ' Usage: CALL &A100,tracknumber,type

10 MEMORY &A0FF : RESTORE 20 : S=0 : FOR T=&A100 TO &A17F : READ A$ : A=VAL("&"+A$) : S=S+A : POKE T,A : NEXT T : IF S<>11553 THEN PRINT"DATA ERROR" : END

20 DATA
FE,02,C0,DD,7E,00,4F,C5,F5,32,5D,A1,3C,32,65,A1,
3C,32,6D,A1,3C,32,75,A1,3C,32,7D,A1,F1,06,05,80,

A1,32,6F,A1,32,73,A1,32,77,A1,32,7B,A1,C1,57,1E

30 DATA

100 ' Test: DATA formatting from track 39 to 0
110 PRINT "Insert a floppy disc and press any key." : CALL &BB18
120 FOR track=39 to 0 step -1
130 PRINT "Formating track" ; track ; CHR$(11)
140 CALL &A100,track,&C1 : NEXT track : PRINT
