Problems for "Backup & Recovery" tool

(SBJ) Problems for "Backup & Recovery" tool

-- par.1

I confirmed the behavior of the following "Backup & Recovery" tool
with the evaluation tools ("bpbf.bat" etc.) shown below.
The "Backup & Recovery" tool shall be revised to fix the following
Discovered Problems (1) and (2).

(To be continued)

### Discovered Problems ###

(1) "Format Partition..." for FAT32 File system

Until the following problems have been fixed, it is necessary
to use the alternative FAT32 Formatter tools shown below.

- "PartitionType" is not 0x0c (FAT32 partition that uses extended int13 services),
and is forced 0x0b (FAT32 partition that does not use extended int13 services).
It should be possible to set 0x0c for using LBA addressing mode.

- PBR-BPB "0eh-0fh Reserved Sectors" is not fixed 0x20,
and is variable, e.g. 0x22 (for 512 bytes per physical/logical sector).
That does not support Partition Alignment of 8 logical sectors unit on the HDD/SSD
which uses AFT (Advanced Format Technology; 4096 bytes per physical sector).
It should be fixed 0x20 to support AFT HDD/SSD.

- PBR-BPB "1ch-1fh Hidden Sectors" is not the offset from the beginning of the disk,
and is forced 0x3f as for Logical Partitions.
It should be the offset from the beginning of the disk as with Primary Partitions.
See also the "Important Reference Links" shown below.

Code:

Table-1. "Format Partition..." for FAT32 File system
Item	Pi (P0 etc.)	L0		Ln (L1 etc.)
=======+===============+===============+===============
MHS	(unch.)		(n/a)		(n/a)
EHS	(n/a)		(unch.)		(unch.)
PTY	0x0b(!=0x0c)	0x0b(!=0x0c)	0x0b(!=0x0c)
PRS	!=0x20		!=0x20		!=0x20
PHS	(OK!)		0x3f		0x3f

(To be continued)

(Continued)

(2) "Restore Partition..." after "Burn Partition on CD or DVD..."

- "EPBR HiddenSectors" of Logical Partition #0 is forced 0x1,
and is not compatible with Logical Partition #n (n=1,2, ...).
It should be compatible with the other Logical Partitions.

- "PartitionType" is set forced 0x0b (FAT32 partition that does not use extended int13 services),
and is changed from 0x0c (FAT32 partition that uses extended int13 services).
It should be unchanged from 0x0c for using LBA addressing mode.

Code:

Table-2. "Restore Partition..." after "Burn Partition on CD or DVD..."
Item	Pi (P0 etc.)	L0		Ln (L1 etc.)
=======+===============+===============+===============
MHS	(OK!)		(n/a)		(n/a)
EHS	(n/a)		0x1		0x800*n
PTY	0x0b<-0x0c	0x0b<-0x0c	0x0b<-0x0c
PRS	(unch.)		(unch.)		(unch.)
PHS	(OK!)		(OK!)		(OK!)

Notes/Legend:

 Pi:	Primary Partition #i {i|i=0,1, ...}
 L0:	Logical Partition #0 (the 1st Logical Partition)
 Ln:	Logical Partition #n {n|n=1,2, ...}

 MHS:	MBR HiddenSectors (not PBR-BPB 1ch-1fh Hidden Sectors)
 EHS:	EPBR HiddenSectors (not PBR-BPB 1ch-1fh Hidden Sectors)
 PTY:	PartitionType
 PRS:	PBR-BPB 0eh-0fh Reserved Sectors

PBR-BPB "1ch-1fh Hidden Sectors" should be the offset from the beginning
of the disk, as for Logical Partitions, as with Primary Partitions.
The offset from the beginning of the disk is MBR/EPBR "StartingOffset" [Sc].
MBR/EPBR "StartingOffset" [Sc] is equal to MBR/EPBR "Boot Record at sector N"
at the title of the "Boot Record" window displayed by "PTEDIT32.EXE".

The following correspondence table is related to the expressions
of "PTEDIT32.EXE" and "bpbf.bat" ("bpb.exe").
And, EPBR "Boot Record at sector N" may be calculated as follows.

Code:

Notes:
 *1 MBR/EPBR "Boot Record at sector N" is displayed at the title
    of the "Boot Record" window.

 *2 EPBR "Boot Record at sector N" may be calculated as follows.

if (LogicalPartitionNo == 0) {
	BootRecordAtSectorN[LogicalPartitionNo]
	 = SectorsBefore[0][ExtendedPartitionEntryNo]
	 + SectorsBefore[LogicalPartitionNo + 1][1];
} else {

See also Table-4. "PTEDIT32.EXE" vs. "bpbf.bat" ("bpb.exe") .

PBR-BPB "1ch-1fh Hidden Sectors" should be the offset from the beginning
of the disk, as for Logical Partitions, as with Primary Partitions.
The offset from the beginning of the disk is MBR/EPBR "StartingOffset" [Sc].
MBR/EPBR "StartingOffset" [Sc] is equal to MBR/EPBR "Absolute sector"
at the top of the window displayed by "Acronis DiskEditor Demo".

The following correspondence table is related to the expressions
of "Acronis DiskEditor Demo" and "bpbf.bat" ("bpb.exe").
EPBR "Absolute sector" of PBR#Li may be calculated as follows.
Each absolute sector of EPBR#Li is calculated as follows.

It was confirmed that a serious and additional problems are existing
in the latest 2014-x64 (and not 2014-x86) version of "Backup & Recovery".

The following problems have been confirmed with plural kind of PCs
and with plural kind of BD/DVD/CD drives.
So the problems are depended on the edition of "Backup & Recovery".
