NAME
dcalc - Converts between unallocated disk unit numbers and regular disk unit numbers.SYNOPSIS
dcalc [-dsu unit_addr] [-vV] [-i imgtype] [-o imgoffset] [-f fstype] image [images]DESCRIPTION
dcalc 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 dls(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(1) ). 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 dls(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 dls -s). The image is the full, original image (i.e. from dd(1)).- -f fstype
- Identify the File System type of the image. Use the -? argument for a list of supported file system types. If not given, the default type for the platform is used.
- -i imgtype
- Identify the type of image file, such as raw or split. Raw is the default.
- -o imgoffset
- The sector offset where the file system starts in the image. Non-512 byte sectors can be specified using '@' (32@2048)
- -v
- Verbose output to STDERR.
- -V
- Display version.
This is useful when using lazarus or keyword searching an image generated by dls. This allows one to identify the original unit address and provides better documentation.
