Hi, this is my first post.
I purchased a 3.5" 1TB SATA hard disk from a car boot sale the other day. It came with a silver external case (enclosure), which I can put the hard disk in.
I inserted the hard disk inside the case and connected the two cables (of the hard disk and the case) with each other. On the back of the case are two ports: a USB 2.0 port and a Power port, as well as a On/Off switch and a 'R/W' lamp. I don't know what to do now because I currently do not have a USB to USB cable at home (so that I can connect the disk with its case to a PC), and I also don't have the type of Power cable it needs (a 6-pin 12V+5V power supply - one which I have never seen before).
Looking at Amazon, there are plenty of USB to USB cables for under £2. For the power supply, I found this: http://www.amazon.co.uk/Estone-Enclosure-Output-Switching-Adapter/dp/B00HH45MDC/ref=sr_1_1?ie=UTF8&qid=1402330228&sr=8-1&keywords=Hard+Drive+Enclosure+6+pin - I'm not sure if this is the right thing.
I would like to use this hard disk as a portable one, like a USB pen drive, however I am confused: Do I NEED to have a power supply, i.e. is it necessary to have electric power for the hard disk to function? I've seen many external hard disks at my school which just function by connecting it to a PC using USB, but the external case/enclosure that I have has a power port on the back, which suggests I NEED to have electric power? Also, is it necessary to have a USB to USB cable to connect the hard disk to a PC to use it as a portable hard disk?
Please help me. Thanks.
