The test patterns used on Solaris and marked with "federal requirements" are:

int purge_patterns[]= {               /* patterns to be written */ 
        0xaaaaaaaa,             /* 10101010... */ 
        0x55555555,             /* 01010101...  == UUUU... */ 
        0xaaaaaaaa,             /* 10101010... */ 
        0xaaaaaaaa,             /* 10101010... */ 
}
