wwt analyze

1.   Syntax

wwt ANALYZE [wbfs_partition]...

2.   Options

Options
Option		Param	Description
-a	--auto		Search for WBFS partitions using '/proc/partitions' or searching hard disks in '/dev/'.
-A	--all		Use all WBFS partitions found.
-p	--part	part	Define a primary WBFS file or partition. Multiple usage possible.
-l	--long		If option --long is set then calculated values are printed too if other values are available. If option --long is set twice calculated values are always printed.

3.   Description

The ANALYZE command analyze files and partitions and prints out the geometry. If no device is defined, all devices are analysed. The files and partitions are not modified and opened readonly.

First ANALYZE looks into the file and search for old WBFS information. Second it makes a calculation like the INIT command for different sector sizes. All data is printed as a table:

The columns (all numbers are printed in hex):

NAME

Short name of the analyze mode:

• HEADER: Result of header analyzing (first 12 bytes).
• INODE-*: Result of INODE-INFO searching.
  • INODE-TIM: The newest INODE found.
  • INODE-CNT: The inodes with the largest equal-inodes-count.
  • INODE-1ST: The first inodes found if not already printed.
• DISCS: Result of searching discs in the WBFS management area.
• CALC #: Example calculation of the INIT function. (see option --long)
• OLD #: Example calculation with the old buggy algorithm. (see option --long)

WBFS magic

Text "ok" if a WBFS magic was found.

WBFS vrs

WBFS version.

HD SECTORS total num

Total number of hard disc sectors of the WBFS-file or WBFS-partition.

HD SECTORS sec size

The harddisk sector size of the WBFS-file/partition.

WBFS SECTORS total num

Total number of WBFS sectors. The maximum if 0x10000 = 65536.

WBFS SECTORS sec size

The WBFS sector size of the WBFS-file/partition.

DISCS max num

Maximal possible discs.

DISCS inode size

The disc info size for a single disc.

ADDITIONAL INFORMATION

Additiional information.

• INODE: most current date and number of equal inodes infos found.
• DISCS: number of discs found in the management area of WBFS.

The output can also be used to setup parameters for the INIT command.
