The array size should be CDB_SIZE and there's 3 missing bytes in the 10-byte WRITE SAME CDB. byte 0: WRITE SAME opcode byte 1: all zeros, ok byte 2...5: LBA = 1, ok byte 6: GROUP NUMBER = 2? Did you mean 0x00, 0x00, 0x02, 0x00? It probably works because scsi-disk ignores bytes 6 and 9, and bytes 7-8 are some nonzero value from the stack, but it would break when changing the array size to CDB_SIZE. Otherwise looks good. Thanks for writing the tests! Paolo
