There is a brute force way to do this: Execute the CLI command DiskChange
on the drive, after you have set the BITMAP_VALID flag in the root block
to invalid. This causes AmigaDOS to newly read the disk's parameters, find
the bitmap invalid and start the validation process (yes, of the WHOLE
disk; I don't know about a way to only register the changes). You know
you can invoke CLI commands from C language and even from AmigaBasic
by use of the dos library function named Execute.
