Disk First Aid
Level: Novice to Expert

Disk First Aid is a utility that verifies the directory structure of any Mac OS formatted disk. Hard disk, floppy disk, and compact disc (CD) drives are examples of disks that can use this format.

If errors are found on a disk, Disk First Aid can be used as a first step to repair them. If a volume has suffered severe corruption, other utility programs or repair methods may need to be used. Disk First Aid looks for errors in these places:
  • Disk volume
  • Extent B-tree
  • Extent File
  • Catalog B-tree
  • Catalog File
  • Catalog Hierarchy
  • Volume Info
  • Search for locked volume name

You can save the results of a verification or repair scan as a SimpleText (text) document.

Disk First Aid cannot scan for deleted files or folders on a disk. Third party products can perform these tasks.


Drive Setup
Level: Novice to Expert

This hard drive utility is used for initializing, updating, partitioning, and testing Apple SCSI and IDE hard disks. You should only used Drive Setup with these computers:
  • Macintosh computers with a PowerPC microprocessor, including PowerPC-based Performa and PowerBook computers
  • Macintosh computers with a 68040 or 68LC040 processor

Notes:
  • You should not use Drive Setup to update a computer that has the Macintosh Processor Upgrade card installed. If the card is installed in a Macintosh 580 or 630 series computer, use the 601 Processor Upgrade control panel to turn off the card before you use Drive Setup. After you update your hard disk, you can turn the card back on.
  • You cannot use Drive Setup to update a PowerBook 150.
  • Consult the materials that came with your computer if you are unsure whether your Macintosh falls into one of these categories.
