+ mode writes to bytes 16 - 31, 48 - 63 aren't allowed). successes match

+ the first write in each programming region succeeds and puts the
+ region into object mode so that the subsequent three writes to the
+ same programming region fail (in object mode a programming region may
+ only be written to once). when writing 512 byte blocks 1 in 2 writes
+ fail with the first write to each programming region succeeding and the
+ second failing. with 513 byte writes the analysis is slightly more
+ complex than with 512 byte writes but the failure rate of 1 in 2 still
