+ * 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.
