Although the error comes from hw/fdc.c code it's probably originates in
block/vvfat.c:vvfat_write(), because fdc.c is calling bdrv_write() and
reports an error if that function fails.
I suggest adding printfs or using gdb. The only two returns that have
no fprintf(stderr, ...) are:
/* Check if we're operating in read-only mode */
if (s->qcow == NULL) {
return -EACCES;
}
and
if (sector_num < s->first_sectors_number)
return -1;
Perhaps one of these is failing?
