1. Make sure you have the latest firmware. Because firmware updates wipe out all data on the drive, you must do this operation as the first step; make sure to back up all existing data first. You’ll need to check with the drive manufacturer or the OEM, depending on whether you purchased the drive as a retail upgrade or as part of an OEM PC. Follow the instructions to complete the firmware update; this typically requires booting from removable media such as a USB flash drive.
2. Set the disk controller to AHCI mode. In the system BIOS, set the SATA controller for Advanced Host Controller Interface (AHCI) operation before installing Windows. This step is crucial. Using the legacy IDE or ATA mode prevents you from installing the proper disk controller driver later and will result in reduced performance.
