Hdd Power Cable - How And Where Can I Find To Replace This? Options

[Leprekaun]

Hi all. I've had Error 07 with my Xbox a number of times now. I thought that at first, it was the HDD that was the problem but after recently getting a new HDD, it worked fine for a while but when I started playing Ninja Gaiden yesterday (has previously happened with Halo as well with my older HDD), the game froze and nothing was happening. I shut off my Xbox and turned it on again and thats when I was told that I've got error 07 again. I've tried disconnecting the HDD power cable and connecting it again and it does work but like I said, it only works for a while (a few days/weeks) and then I get error 07 again so I'm quite sure that the problem is with the HDD power cable so would anyone know how to replace it and where can I purchase a power cable to replace it? I don't want to open up a faulty PSU and yank a cable out of there because of endangering myself of electric shock from the voltage stored in the capacitors. Thanks.
