PROGRAM:

NAME


blkcalc - Converts between unallocated disk unit numbers and regular disk unit numbers.

SYNOPSIS


blkcalc [-dsu unit_addr] [-vV] [-i imgtype] [-o imgoffset] [-b dev_sector_size] [-f
fstype] image [images]

DESCRIPTION


blkcalc creates a disk unit number mapping between two images, one normal and another that
only contains the unallocated units of the first (the default behavior of the blkls(1)
program). One of the -d, -s, or -u options must be given. If the -d option is given,
then the unit_addr value is the disk unit address in the regular image (i.e. from dd ).
If the unit is unallocated, its address in an unallocated image is given. If the -u
option is given, then the unit_addr value is the disk unit address in the unallocated unit
image (i.e. from blkls(1) ). Its disk unit address in the original image is determined.
If the -s option is given, then the unit_addr value is the disk unit address in the slack
image (i.e. from blkls -s). The image is the full, original image (i.e. from dd).
blkcalc was called dcalc in TSK versions prior to 3.0.0.

-f fstype
Identify the File System type of the image. Use '-f list' to list the supported
file system types. If not given, autodetection methods are used.

-i imgtype
Identify the type of image file, such as raw. Use '-i list' to list the supported
types. If not given, autodetection methods are used.

-o imgoffset
The sector offset where the file system starts in the image.

-b dev_sector_size
The size, in bytes, of the underlying device sectors. If not given, the value in
the image format is used (if it exists) or 512-bytes is assumed.

-v Verbose output to STDERR.

-V Display version.

image [images]
The disk or partition image to read, whose format is given with '-i'. Multiple
image file names can be given if the image is split into multiple segments. If
only one image file is given, and its name is the first in a sequence (e.g., as
indicated by ending in '.001'), subsequent image segments will be included
automatically.

This is useful when keyword searching an image generated by blkls. This allows one to
identify the original unit address and provides better documentation.

EXAMPLE


# blkcalc -u 64 images/wd0e
