Apple HD SC Setup was a small software utility that was bundled with various versions of the Mac OS
made by Apple Computer
. Introduced with Apple's first SCSI
hard drive, the Hard Disk 20SC
in September 1986, Apple HD SC Setup can update drivers and partition and initialize hard disk
s. It was often used when reinstalling the operating system of an Apple Macintosh computer, or to repair corrupt partition information on a SCSI
hard disk. Prior to its introduction, formatting of disks was handled exclusively by the Mac's Finder application, or third party formatting utility software customized for a specific disk drive.
The version of Apple HD SC Setup that shipped with the Mac OS was only able to manipulate hard disks that featured Apple ROM
s. Versions of the program that were bundled with A/UX
, however, could be used with any SCSI disk. A third-party patch was released enabling standard editions of Apple HD SC Setup to work on any SCSI disk.
In the mid 1990s, when Apple began shipping computers using ATA hard drives, Apple HD SC Setup was joined by Internal HD Format, which could only format IDE drives. Eventually, both Internal HD Format and Apple HD SC Setup were superseded with Drive Setup
in 1995, which combined SCSI and IDE formatting abilities, and ultimately by Disk Utility
