While that *may* work, I would guess that the scratch was outside the
written data area on the disk and all you did was tell the drive that
the unwritten portion of the disk was _not damaged_.  A scratch in the
data area of the disk would certainly have resulted in damaged data
tracks and corrupt data (that may or may not have been correctable). The
severity (width) of the scratch would also have been a factor.
