- * Definitions needed to perform bad sector revectoring ala DEC STD 144.
- *
- * The bad sector information is located in the first 5 even numbered
- * sectors of the last track of the disk pack. There are five identical
- * copies of the information, described by the dkbad structure.
- *
- * Replacement sectors are allocated starting with the first sector before
- * the bad sector information and working backwards towards the beginning of
- * the disk. A maximum of 126 bad sectors are supported. The position of
- * the bad sector in the bad sector table determines which replacement sector
- * it corresponds to.
- *
- * The bad sector information and replacement sectors are conventionally
- * only accessible through the 'c' file system partition of the disk. If
- * that partition is used for a file system, the user is responsible for
- * making sure that it does not overlap the bad sector information or any
- * replacement sectors.
