The first block in the first pair will be Block 0, the second block in the first pair will be Block N (where N is number of last block for testing). Butterfly Read mode is similar to Read mode difference only in blocks' order.The program tests blocks one by one from minimum to maximum. The program sends the block of data to the drive and the drive writes the block (All previous data in the block on the drive will be overwritten with the pattern and cannot be recovered after that!) The program measures operation time for each block. In Erase mode the program prepares block of data field with special pattern and an LBA number.
