A Serial Advanced Technology Attachment (SATA) cable connects an internal hard disk drive to a motherboard and power supply. The Universal Serial Bus (USB) provides for peripheral and external connections such as mice, keyboards or storage devices. Attaching a hard drive to a USB converter allows you to make your own SATA-to-USB connector. Converting a SATA hard drive to USB permits the external connection of a hard drive to any computer supporting USB 2.0.
Install any software included with the converter before attaching the device to your computer. Put on an antistatic wrist strap to protect the SATA hard disk from electrostatic discharge.
