The current code generates 8 oob sections:
 | 
						|
S1	1-5
 | 
						|
ECC	6-8
 | 
						|
S2	9-15
 | 
						|
S3	16-21
 | 
						|
ECC	22-24
 | 
						|
S4	25-31
 | 
						|
S5	32-37
 | 
						|
ECC	38-40
 | 
						|
S6	41-47
 | 
						|
S7	48-53
 | 
						|
ECC	54-56
 | 
						|
S8	57-63
 | 
						|
 | 
						|
Change it by merging continuous sections:
 | 
						|
S1	1-5
 | 
						|
ECC	6-8
 | 
						|
S2	9-21
 | 
						|
ECC	22-24
 |

S3	25-37
 |

ECC	38-40
