 Yes, looks like all files above block 2097151 are corrupted.
 From xorriso:
 {{{

 File data lba:  0 ,   703998 ,   524288 , 1073741824 , '/OSb/bigFile1'
 File data lba:  0 ,  1228286 ,   524288 , 1073741824 , '/OSb/bigFile2'
 File data lba:  0 ,  1752574 ,   524288 , 1073741824 , '/OSb/bigFile3'
 File data lba:  0 ,  2276862 ,   524288 , 1073741824 , '/OSb/bigFile4'
 snip
 }}}
 Checking MD5s inside haiku results in wrong checksums beginning from
 bigFile4 and all following files.
