I received the cable kit (long past the expected delivery date) and was eager to connect it to my computer. I was looking to connect a hard drive from another computer to my new one and believed that this product would be what I needed. To test it out, I had an older hard drive that I connected first. I used the power cord and the adapter to connect it to the power cable for the hard drive. For some reason, the power cord delivered too much power and it fried the hard drive. I resolved to connect the hard drive that I wished to use directly to the hard drive cable inside my computer and use the USB cable to connect from my SATA cable. This worked perfectly. Be careful of the power cable and the adapter. By the way, I tried using them to power a fan from an old computer, and they worked fine.

I feel kind of petty saying this about a product that only cost nine bucks and shipped for free, but sonce Wal-Mart is asking, I might as well be honest about it. First the good news: the shipping was free, and the order arrived more than a week before the web site said to expect it. Now the bad news: the power supply shipped with the product does not work. The LED does not illuminate when you plug it in, and nothing powers up when you connect it. I purchased one of these in a computer store several years ago (and subsequently misplaced it) and it does exactly what it is supposed to when it works, but without a power supply, it won't do a thing. Unfortunately, he connector is unique, so I was unable to use any of the other PC type transformers I have laying around the house as a substitute. His thing cost so little, I feel kind of bad about asking Wal-Mart for a replacement/refund, since all the shipping back and forth would probably exceedthecost of the product, even if I knew how/where to request that. Anyway, bad power supplies are something you can get with any kind of electronics,soil not holding it against anyone!
