/*
* Format for volume header information
*
* The volume header is a block located at the beginning of all disk
* media (sector 0). It contains information pertaining to physical
* device parameters and logical partition information.
*
* The volume header is manipulated by disk formatters/verifiers,
* partition builders (e.g. fx, dvhtool, and mkfs), and disk drivers.
*
* Previous versions of IRIX wrote a copy of the volume header is
* located at sector 0 of each track of cylinder 0. These copies were
* never used, and reduced the capacity of the volume header to hold large
* files, so this practice was discontinued.
* The volume header is constrained to be less than or equal to 512
* bytes long. A particular copy is assumed valid if no drive errors
* are detected, the magic number is correct, and the 32 bit 2's complement
* of the volume header is correct. The checksum is calculated by initially
* zeroing vh_csum, summing the entire structure and then storing the
* 2's complement of the sum. Thus a checksum to verify the volume header
* should be 0.
*
* The error summary table, bad sector replacement table, and boot blocks are
* located by searching the volume directory within the volume header.
*
* Tables are sized simply by the integral number of table records that
* will fit in the space indicated by the directory entry.
*
* The amount of space allocated to the volume header, replacement blocks,
* and other tables is user defined when the device is formatted.
