SCSI Calls Translated for IDE Devices


Q: My application makes various SCSI calls to obtain information about devices attached to the SCSI bus. Since I also need to support the new IDE drives that are in some Macintosh models, I need to know if SCSI calls are automatically translated for IDE devices or if there is a new API for these drives. Where can I get more information about Apple's use of IDE drives?

A: IDE is an industry standard. For information on the standard and a full description of the ATA Manager, see ANSI specification number X3T9/0948D, revision 2, which can be ordered from Global Engineering at:

Phone: 800-854-7179
Fax: 303-792-2192

Although it is not documented, the ATA Manager does support the 'Identify Drive Command', which returns the IDE drive model and serial numbers (if the drive manufacturer supports this).
