EraseDisk is a Java 1.4 graphical (GUI) application to erase and test disk drives or flash drives. Large temporary files are created and filled with zeros, ones, or pseudo-random data. Previously deleted files are overwritten. Existing files are not affected. This cleans up an old disk before it goes in a new location. Don't trust a new disk until you write data, then read to confirm. One complete test is usually enough. (Repeated testing may degrade flash drives.)
