- * 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.
