You have to be careful not to pinch your fingers between them but they're cool to play with.

If it's clicking that means it's unable to read the disc due to a hardware failure. I've had some luck placing the whole drive in the freezer for a couple hours and then copying the important stuff off immediately but if that doesn't work either pay the $ for professional recovery or throw away the drive because I can guarantee you won't fix it by opening it.

Well, they want 1000 dollars or more. What about putting it in the freezer while I use it? Would't the heat of the drive and the coldness of the freezer, or fridge, which I could adjust if someone gave me some guidance, keep it at a steady rather cold temp? The flat wire is long enough, and the power wire can be any length I want it to be. Remove NOPSAM to email me. Please let me know if you have posted also.
