Шаблон:Short description Шаблон:Infobox Software Disk First Aid is a free software utility made by Apple Inc. that was bundled with all computers running the classic Mac OS.[1] This tool verifies and repairs a limited number of directory structure problems on any HFS or HFS Plus hard disk or volume.[2]

Disk First Aid is a very simple tool, with it only being able to detect and repair directory damage[3] and many books are critical of its sometimes inaccurate reporting of errors, and often suggest to run the tool more than once to ensure a consistent result.[3][4][5] Disk First Aid is located in Applications:Utilities:Disk First Aid.[4] The classic Mac OS provides an option to run Disk First Aid on startup, although it has been reported that it provides little gain and sometimes can amplify a problem.[4]

Its capabilities were incorporated into Disk Utility in macOS.

Situations to use the tool

  • Frequent system crashes,
  • Disappearing files,
  • Files changing size,
  • Problems copying files from one place to another,
  • Problems saving files,
  • Cryptic error messages,[5]

as well as for general maintenance every 6 months.[6]
