i have no idea what it's for, but 2ond and 3rd were just wrongly bought.anywayz how can i use them?
First one connects the hard drive to the motherboard its a SATA cable And do what I do keep them around for when I need them and then forget where they are so I can't find them and I have to go out to the store to get a new one
The first one is a SATA hard drive cable - data cable The second is a USB male to male connector cable, The third one is a Ethernet cable. If you have a SATA hard drive, and connectors in your computer you cna use the first one.
