NAME

       Data::ParseBinary::FileSystem::MBR - Parsing the partition table

SYNOPSIS

	   use Data::ParseBinary::FileSystem::MBR qw{$mbr_parser};
	   my $data = $mbr_parser->parse(CreateStreamReader(File => $fh));

       Can parse the binary structure of the MBR. (that is the structure that tells your computer what partitions exists on the drive) Getting the
       data from there is your problem.

       This is a part of the Data::ParseBinary package, and is just one ready-made parser.  please go to the main page for additional usage info.

NAME

     mbrlabel -- update disk label from MBR label(s)

SYNOPSIS

     mbrlabel [-fqrw] [-s sector] device

DESCRIPTION

     mbrlabel is used to update a NetBSD disk label from the Master Boot Record (MBR) label(s) found on disks that were previously used on
     DOS/Windows systems (or other MBR using systems).

     mbrlabel scans the MBR contained in the very first block of the disk (or the block specified through the -s flag), then walks through every
     extended partition found and generates additional partition entries for the disk from the MBRs found in those extended partitions.

     Each MBR partition which does not have an equivalent partition in the disk label (equivalent in having the same size and offset) is added to
     the first free partition slot in the disk label.  A free partition slot is defined as one with an fstype of 'unused' and a size of zero
     ('0').  If there are not enough free slots in the disk label, a warning will be issued.

     The raw partition (typically partition c, but d on i386 and some other platforms) is left alone during this process.

     By default, the proposed changed disk label will be displayed and no disk label update will occur.

     Available options:

     -f 	Force an update, even if there has been no change.

     -q 	Performs operations in a quiet fashion.

     -r 	In conjunction with -w, also update the on-disk label.

     -s sector	Specifies the logical sector number that has to be read from the disk in order to find the MBR.  Useful if the disk has remapping
		drivers on it and the MBR is located in a non-standard place.  Defaults to 0.

     -w 	Update the in-core label if it has been changed.  See also -r.
