Drives supporting AES automatically encrypt all data that is written and automatically decrypt the data when it is read. More recently, ATA security has been augmented by drives that support internal encryption/decryption using the Advanced Encryption Standard (AES). If you lose or forget them, they usually cannot be recovered, and you will never be able to access the data on the drive. Note that these passwords are very secure. Because it was then incorporated into the official ATA-3 standard (finally published in 1997), most other drive and system manufacturers have also adopted this, especially for laptop systems and 2.5-inch and smaller drives. The proposal adopted in the ATA specification was originally from IBM, which had developed this capability and had already begun incorporating it into ThinkPad systems and IBM 2.5-inch drives. Support for drive passwords (called ATA Security Mode) was added to the ATA-3 specification in 1995. This is why low-level format or initialization programs can be so specific to a particular manufacturer’s ATA drives and why many manufacturers make their own LLF programs available. Often, vendor-unique commands control features such as low-level formatting and defect management. Certain vendors often use these commands for features unique to that vendor. Many other enhanced commands are available, including room for a given drive manufacturer to implement what are called vendor-unique commands. Several freely available programs such as HWiNFO ( or CrystalDiskInfo ( can execute this command, then translate and report the information onscreen.

Through this command, any program (including the system BIOS) can find out exactly which type of drive is connected, including the drive manufacturer, model number, operating parameters, and even serial number of the drive. This command causes the drive to transmit a 512-byte block of data that provides all details about the drive. Perhaps the most important is the IDENTIFY DEVICE command. These commands are an optional part of the ATA interface, but several of them are used in most drives available today and are important to the performance and use of ATA drives in general. In addition to supporting all the WD1003 commands, the ATA specification added numerous other commands to enhance performance and capabilities. All IBM-compatible systems have built-in ROM BIOS support for the WD1003, so they essentially support ATA as well.

All ATA drives must support the original WD command set (eight commands) with no exceptions, which is why ATA drives are so easy to install in systems today. The ATA command interface was modeled after the WD1003 controller IBM used in the original AT system. One of the best features of the ATA interface is the enhanced command set. The following section lists some of the elements and functions the ATA specifications define. The ATA specifications define the signals on the cables and connectors, the functions and timings of these signals, the cable specifications, the supported commands, the features, and so on. The ATA standards have gone a long way toward eliminating incompatibilities and problems with interfacing SATA and PATA drives to systems. Upgrading and Repairing PCs, 21st Edition
