I had my ATV die on me and was planning to replace the hard drive to fix it. Once I got into the machine, I hooked up the HD to my computer and it looked just fine so my conclusion was it is NOT the hard drive. I bought a new ATV and am wanting to sell the old one, but am concerned about the purchaser getting my iTunes account info off the hard drive. Does anyone know how to remove that info without wiping out the HD? I know a HD without the ATV information reders the ATV pretty much useless. Would love any input. Thanks!
