Serial advanced technology attachment (SATA) hard drives can be set to integrated drive electronics (IDE) mode, or advanced host controller interface (AHCI) mode. IDE mode enables a SATA hard drive to run in the same way as an IDE hard drive, whereas AHCI mode improves read-write performance and enables hot-swapping (the ability to replace SATA devices without turning off the PC). AHCI mode, on the other hand, isn't compatible with older operating systems as IDE mode is.

You can change how a SATA hard drive is configured in the computer's basic input/output system (BIOS) setup.
