.SomeSATAdriveshave
both conventional 4-pin peripheral power connectors as well as SATA 15-pin power
connectors, in which case you can use one or the other, but not both simultaneously.
If your drive has only a SATA power connector and your power supply doesn't have
SATA power connectors available, you might need to purchase a peripheral-to-SATA
power cable adapter if one was not provided with your drive. This type of adapter
changes a standard 4-pin peripheral power connector into a 15-pin SATA power con-
nector.Ifnecessary,youcanalsouseaY-splittercabletocreatetwopowerconnectors

System Configuration (Drive Detection)
Older systems often required that drives be manually identified and configured in the
BIOS Setup. The BIOS in modern PCs incorporates automatic drive parameter detection
