Hi All, Ok, I think I already know the answer to this but I'll ask it just the same. My flat panel 15" iMac died an UGLY death to the tune of having disk utility tell me I had a bad hard drive, salvage what I could & get a hard drive that worked. The message all but offered it's condolences! I'm paraphrasing but that was the gist of the message. So... having said that, is there any way that I can deauthorize my dead drive or do I just have to keep it in my list of viable computers until I reach my limit? Eventually I will replace the drive - but this information (authorizing info) is attached to the ATA or no? Best, joAnn
