Recovery of supposedly erased data from magnetic media is easier than commonly believed; Magnetic Force Microscopy (MFM) lets any moderately funded opponent recover the last two or three layers of data written to disk. Wipe attempts to make this more difficult by repeatedly overwriting special patterns to the files to be destroyed, using the fsync() call and/or the O_SYNC bit to ensure that there is a file barrier between passes and that each pass is completely written.
