Hard Disk Drive

The iMac computer has an internal hard disk drive. The drive uses the extended IDE (integrated drive electronics) interface, which is also referred to as the ATA interface. The implementation of the ATA interface on these computers is a subset of the ATA/IDE specification, ANSI proposal X3T10/0948D, Revision 3 (ATA-3).

The software that supports the internal hard disk is the same as that in previous Macintosh PowerBook models with internal IDE drives and includes DMA support. For the latest information about that software, see Technote #1098, ATA Device Software Guide Additions and Corrections, available on the world wide web at

The web page for Technote #1098 includes a link to a downloadable copy of ATA Device Software Guide .
