Yeah I used trackdisk.device from Sonic and downloaded also fat95 from aminet to use fat filesystem.

here is my mountlist as suggested by Sonic in trackdisk readme

/* MS0: fat95 PC file system for floppy #0 */
/* $VER: fat95 file system 3.06 (08-Aug-2002) by Torsten Jager */

FileSystem = l:fat95
Device = trackdisk.device
Unit = 0 /* change drive number here */
Flags = 0
LowCyl = 0
HighCyl = 79
Surfaces = 2 /* bootblock values have priority over these */
BlocksPerTrack = 18
Buffers = 20
BufMemType = 1
BootPri = 0
Stacksize = 4096
Priority = 5
GlobVec = -1
DosType = 0x46415400

MS0; device is not mounted, on startup mos ask me to assign/mount the device.
