A write error verification method of a writing apparatus verifying a write error after a write operation being started in the writing apparatus to which layout data containing a figure pattern to be formed is input and which forms the figure pattern on a target object based on the layout data input, the write error verification method includes: if a write error occurs in a process between input of the layout data into the writing apparatus and inspection of the target object on which the figure pattern is formed, selecting a part of the layout data necessary for operation of a function that has caused the write error; extracting parts of the layout data corresponding to a selected part of the layout data for all of a plurality of portions of the target object if a pattern indicated by the selected part of the layout data is arranged at the plurality of portions of the target object; creating verification data by deleting at least one parts extracted for at least one portions other than a portion that has caused the write error from extracted parts of the layout data and by using remaining data; and reproducing the operation of the function that has caused the write error using the verification data to output a result of the reproducing.
